So I just ran into an issue where all GSX vehicles are creating this stuttering effect. The sim and the plane itself is running smooth with no stutters or low fps, but it's the actual GSX vehicles and tow truck that are stuttering. Also, when inside the cockpit view, the stutters are also visible. when I remove GSX and use the default pushback system or Better Pushback mod, everything is silky smooth.
All GSX settings are at default. It was working properly a few days ago before some of the recent updates so I don't know if one of the updates broke something.
Anybody have any ideas or having same issue?
Specs:
7950X3D
RTX 4090
32 GB DDR5
1 TB NVME
Thanks

We already discussed this on the GSX Creators channel on Discord and, the animation stuttering doesn't seem to be caused by the GSX update, it might just have happened coincidentally with some other update, possibly a Windows or a video drivers update.
To test this theory, we HAVE posted TWO new OFFLINE installers to test:
Version 2.7.6 from last September:
https://app.box.com/s/hcjc7sx6uz8r5a3u1sq1jciqo0xllj2f
A BETA version derived from the latest 2.8.2, with some optimizations to reduce the number of Simconnect calls:
https://app.box.com/s/ino7cuh2yql2zhm61o74y5lweq7c8xma
The 2.7.6 version will downgrade the complete GSX code, including the sound that was the most important change and, as of today, everybody that tested it hasn't noticed any difference, indicating the stuttering hasn't been caused by the latest GSX Update.
The new BETA includes a bit of optimizations to reduce the number of simconnect calls in some animations (baggage loaders, mostly) and also in this case users who tested it didn't report any difference, indicating the problem is not too many simconnect calls made by GSX, so it really points out to something completely external to it, like a Windows update or a driver update.

Thanks for the reply. Ok, I do remember updating my GPU drivers on the same day I updated GSX. I was on vacation for two weeks so it had been a while since I had last used the sim.
I will revert back my GPU driver and report back later today.
Thanks again!
-
Well, I was waiting for the newest update to come out and this if anything changed, but i still got the animation stuttering. I have downgraded GPU drivers, but still problem occurs. It was working perfectly fine until I updated to 2.8.2. Ohh well, I'm fine not using GSX for now. Sim seems to run a lot smoother without it anyways!
-
Are you on SU14 Beta? In general, both GSX and the Sim are very stuttery with SU14B and the recent updates. Hope this gets resolved!
-
It was working perfectly fine until I updated to 2.8.2.
Please stop saying the 2.8.2 update caused this, nothing in it could possibly have any effect on animation, since the only important change was the sound. And of course, each and every user who tried the 2.7.6 version I posted in the message you quote, confirmed it didn't make ANY difference so no, it wasn't the update.
Ohh well, I'm fine not using GSX for now. Sim seems to run a lot smoother without it anyways!
If you are saying the fps is lower when GSX is doing something like boarding/deboarding which involves lots of object, that's obvious. If you are saying the sim is smoother because GSX is not installed, I'm sorry, but that's just impossible, since if you are not calling GSX, is not really doing anything, other than wait for you to open its menu.
-
So let me get this straight. Before updating to 2.8.2 GSX, was working fine with no stutters of these pushback towtrucks/catering/fuel truck. But as soon as I updated to then latest 2.8.2, without having changed anything else other than updating my GPU drivers, I get these stutters, and you say it’s not GSX causing?? Smh, you can’t make this up. Thanks!
-

Nope. Su13
-
Yeap, I get stutters all over the place with GSX now unfortunately, I had to stop using it, it's unplayable this way. It wasn't before, so yes it's upon a certain update that this started because definitely some updates ago, vehicles did not stutter. Now as you pushback with towbar and non towbar trucks, your aircraft stutters because of GSX vehicles stutter. As you say, with other pushback addon's all is smooth.

As I've said, each and every user who tried the 2.7.6 version I posted in the message you quote, confirmed it didn't make ANY difference so no, it wasn't the update. YOU can try the 2.7.6 as well, so you can convince yourself it wasn't the update.
-

ycristia is certain it started exactly with 2.8.2, you are saying for you it started some updates ago. This should be ample evidence it can't possibly be GSX but, something else that changed in the sim or the PC configuration that, for you happened before than him.
The thing is, GSX updates are so frequent, that's very easy to say a "GSX update caused this", just because that with so many updates, there's a very high chance they would happen coincidentally to something else that changed in the meantime.
Otherwise, each and every user reporting stuttering, would all said it happened after the SAME GSX update, which is not what is happening.
-
I have tried everything and even reinstalled windows and msfs. I doubt this is something on our systems as every report i’ve seen, it is mentioned that it started after the 2.8.2 update.

Well then, good thing I saw your post. I was considering reinstalling windows and MSFS but this pretty much confirms it. Let's see if they can figure it out then.
-
I hope this can get fixed in any way. It's a bit immersion breaking.

It's difficult to fix something that can't be replicated, this is what I see here:
Do you see something different ?

This is what it looks like when i use GSX pushback.

-
exactly the same as mine, unusable.
-
Yep. This is exactly what I'm getting.
-
Regarding the movement of service vehicles, mine is even worse. Pushback, yeah, kind of the same as above. Sometimes it makes even a bigger jump.

I'm not sure why you post the same post again.
Because maybe somebody might not have seen it, since it was on the previous page ?

So you ignored my video where i showed the issue we all have? This can’t be ”issue on our end” because so many people have reported this after 2.8.2, here and on discord.

I don't know what you are trying to say here with "ignoring".
Nobody is doubting your video so yes, I understand you have issues. But if they were GSX issues, those should have happened to *everybody* that has GSX, not just a few people. The video I posted is just to show GSX as such doesn't have that issue, so it's helpful for you and others affected to check what else might be.
And since you mentioned the Discord channel, I'm sure you know some affected users there were sure it was "caused by latest update", so we made available on offline installer for a previous older version from last September, and every user who tried it, said it made no difference.
If that's not enough proof the problem is neither caused by the latest updates nor by GSX (even if you decide to "ignore" MY video), I don't know what else is.
Is that's still not enough proof, here's latest video from CptCanada, very well-known YouTuber flying almost every day, no issues I can see, with AI traffic, streaming software in the background:

I only searched for videos uploaded this week, so they surely have the latest update.

Maybe it's a graphic setting interfering. But I can't imagine what that could be.
(I'm on DX11 by the way)
-
Stutters in all GSX vehicles. I'm on DX12, FG on and frames capped via NCP to 100 fps.
-

So we can exclude DX11 vs. DX12 as a reason.
-

Which would of course lead to the next question:
- Have you tried without it, and with different fps settings like 100% monitor, 50% monitor, etc ?
-
Nop, because other vehicles like ai traffic and street vehicles traffic are perfectly smooth and so is my sim with this settings, the issue is GSX stutter vehicles, so nothing to touch on my end!

Ok, I've tried everything and still can't get GSX to run smooth again.
I just did a clean install of Windows 11. First thing I did was install my chipset drivers and latest GPU drivers. Installed MSFS and ran it vanilla with latest version of GSX. Still, the stutters are happening. So with a fresh install of windows and a vanilla MSFS I can only assume GSX is the one with the problem.
I didn't have this issue before. I don't even remember what version I was in GSX as it had been a long time since I had updated it to 8.2. So I can't even say what version was stable for me but I know it was one around August to early September. Again, not clear which version.
The only thing I can think of is maybe GSX is not playing well with 4k resolution as this is what I'm currently using. Don't even know if that could be a cause but GSX definitely ain't liking something now.
Are you on 4K?
These are my specs:
7950X3D
Asus x670E Crosshair Hero
32GB Gskill Neo DDR5
Zotac 4090
1TB NVME
NZXT 360 AIO Cooler
TM Warthog HOTAS
TM TPR Pedals
Cat3Design Tiller
Virpil WarBRD-D Base
LG C2 42 inch 4K TV
All these hardware was working perfectly fine before with GSX. Before I updated to 2.8.2.
So I've ran out of ideas on what might be the issue if there was one on my end. That just leaves GSX itself now.

Been having the same issue with gsx vehicles stuttering ever since I built my new pc in late October. I was first running on DX11 but later switched to DX12 with Frame generation on, which made no difference. I've been trying to solve the issue since it started but can't figure it out. It wasn't happening on my old pc. Whether 2.8.2 is the isssue I'm not sure because my last flight on my old pc was a few days after 2.8.2 had released. I can't remember for sure whether I had updated to 2.8.2, but I usually check gsx for updates via fsdt installer almost every day so there is a high possibility that I was running 2.8.2 without any issues. The stuttering happens with every aircraft I have tested so far: PMDG 737, Fenix A320 and FBW A320Neo. It happens at both default and addon scenery. I do recall the stuttering smoothening out or almost dissapearing completely when at heavy scenery where fps is closer to 30fps than the usual 40-60fps I get. If I'm correct this seems to point to SimConnect not being able to keep up or something like that. The next question is how can it be fixed then? I've seen plenty of people with similar or the same pc specs as mine running MSFS with GSX at the same fps with no problems. I also tried closing and uninstalling 3rd party software that uses SimConnect and also unplugging any peripherals that I felt might have been contributing. No difference. I have updated both the chipset drivers and the Nvidia drivers to no avail. The Nvidia drivers have had 2 or 3 updates since building my pc, none of them have made any difference. I don't really know how to check whether a windows uppdate is the problem or not.
My specs:
Ryzen 7 7800x3d
Nvidia RTX 4090 (MSI suprim x)
32GB G.Skill trident z5 neo rgb (EXPO not enabled, have tried enabled)
1TB Samsung nvme for Windows and a few other programs (gsx also on this drive)
2TB samsung nvme for flightsim and games
Logitech Extreme 3D Pro
Honeycomb Alpha and Bravo
Saitek rudder pedals
Asus MG278 2560x1440p @144hz

I'm on lower res than 4K and also have the problem. So exclude that.
-
If I'm correct this seems to point to SimConnect not being able to keep up or something like that.
It's possible. If your fps is too high, since animations are linked to the frame rate, the traffic over Simconnect might increase to the point it can't keep up with everything.
The next question is how can it be fixed then?
If this theory is correct in your case, just lock the fps at 30 and see if it improves.
-
And that's a very poor solution to the thousands of simmers like me that uses FG and DX12, I think you can do better.
-
This would also raise the question, why it was good some time ago and then appeared suddenly.
-
And that's a very poor solution to the thousands of simmers like me that uses FG and DX12, I think you can do better.
It was just to TEST if the problem in HIS case was caused by too high fps.
And no, FG doesn't have anything to do with this, the frames created by the video card are completely unknown to the simulator, which is easily verified by noticing the frame rate counter in the sim is not the one obtained due to FG, for which you need a frame counter that operates at the driver level to be visible.

Hey Umberto,
I assume you had the ground vehicle acceleration (when far away) on in your video? (me too by the way, just want to be sure)
And could you try that with auto mode (automatic handling)?
(Just trying to find out what the reason is)
@everybody else: do you have anything running besides couatl engine (e.g. FSUIPC, some passenger simulation, FSLTL, etc. etc.)
Best wishes
-
I assume you had the ground vehicle acceleration (when far away) on in your video? (me too by the way, just want to be sure)
Yes, of course but, even if I didn't, the vehicles acceleration option doesn't work by increasing the frequency of Simconnect calls made to move the vehicles but, instead, it just changes the distance they move at each frame so, it won't many any difference.
-
Yeah, I'm not thinking about simconnect as the only possible cause for this. I try to see what could be different in general.

Have you by any chance been able to figure out the culprit?
-
Not yet. I need some feedback to find out what's common on system who have the stutters.
@everybody else: do you have anything running besides couatl engine (e.g. FSUIPC, some passenger simulation, FSLTL, etc. etc.)
One reason could be some graphic settings. Another reason could be simconnect issues. Don't know yet.

This is occurring in P3D as well. Pushback also stutters along with the aircraft as its moving.

Yeah I sadly unlinked GSX from the sim and am just using Pushback Helper until something else comes along or GSX finds a fix. Let's see.

Hi to all,
first of all i keep notes of every single operation on my pc, included changes of drivers, windows update and so on.
Then after a lot of tests in 2 pc i am pretty sure the the cause of this issue is the windows upadte KB5031904 and .NET Framework 3.5, 4.8 e 4.8.1 on windows 10.
If i use GSX version 2.8.8 but in a pc that have KB5031224 and .NET Framework 3.5, 4.8 e 4.8.1 the problem does not appear.
My two cents.

So if this is the case, then doesn't GSX have to find a fix? I mean, programs need to be compatible with OS, not the other way around. Hopefully GSX devs can figure out something.
-
For what its worth I also have bad stuttering of the GSX vehicles and the same
KB5031904 with my Windows 10 installation.
Not sure when it started, but this stuttering issue was not present in the more remote past.

Having the same stuttering issue - occurred for the first time in early November, after several flights I got frustrated and didn't touch it in the hope upcoming updates would fix it. Well neither the MSFS, nor GSX, further Windows or NVIDIA Driver updates did. So no idea what to do anymore to make it usable again :'(
According to my System I'm running on KB5032907 with my WIN10 install.
Also completely cleared the community folder but the GSX files, used different locations, different planes - gave Couatl resource priority on task manager, un-installed and re-installed it and GSX - no changes at all. The animations of the passengers boarding, or de-boarding as well as the movements of all vehicles is just stuttery
Spec.:
7800x3D
32GB DDR6 @6000MHz
RTX3080

I have exactly the same stuttering issue which I think started in October, can´t say exactly when, also tried running only GSX with empty community folder except for GSX but still stuttering of all vehicles.
Spec:
Windows 10
I7 10700K
64GB DDR4
RTX 3090 ROG STRIX
The MSFS itself is running very smoothly without stuttering on my system with for example PMDG 737 and addon payware airports, the only stuttering is the GSX vehicles themself during the drive to and from the aircraft

Seems like it can be really pinned down to Windows 10 users only - or is anybody experiencing those issues with win11 as well?
-
I want to add that it's not only every vehicle that stutters, but also the 3d animated people walking. The only exception seems to be the people loading catering from the catering trucks, from what I,ve observed they don't seem to stutter at all while walking between the truck and the aircraft. Is anyone else having the same issue or is it only the vehicles?
-

Same - all people walking are affected from stuttering but the catering guys and also the guys loading the baggage from the trailer on the loader and vice versa. They having smooth animations.

Me 2, windows 11, same stutters in all vehicles.

Tinkered around a bit today and observed the animations - it seems that only vehicles and persons with variable movement paths are affected.
Not affected by stuttering:
>> The service workers bringing in and out the beverage trolleys
>> The ramp agents loading and unloading the luggage from/onto the belt vehicle
>> The Marshaller when arriving - also the Gangnam Style dance he does from time to time after a good parking is completely free of any stuttering
Those guys are being spawned in a certain location and always execute the same walking path - I think there is no variable in there.
Affected by stuttering:
>> passengers when boarding / de-boarding
>> crew when boarding / de-boarding
>> The ramp agent connecting/disconnecting the gear pin and walking with the plane during push back
>> the tug itself, while it is getting to the plane and also during the push back and driving back to the gate
>> all service vehicles arriving the plane and when leaving it again
My impression after above observations is, that every animation which is somehow related to following a path which is not always the same is affected from the stuttering.
Animations which are "default" - no idea how to describe it better in englisch sorry - its not my first language - and are just "replayed" every time are smooth.
My knowledge in IT is limited but this does not seem to my like a GPU driver issue, CPU overload or something hardware related - in that case all animations would stutter the same.
Can anyone confirm above observations?

Yes, it's the same for me and everyone having this issue. It is not a hardware issue. It's something that GSX has to fix.
-
Yeah, exactly the same for me too. As we are still fishing in muddy waters here, one question out if interest:
How many GSX profiles do you have in your profile folder? Cause I have a lot.

I have 62 profiles............

Same issues for me, i thought this was just a GSX feature.. Very stuttery pushbacks
(is it smoother on default / asobo aircraft?)
-
I mean, programs need to be compatible with OS, not the other way around. Hopefully GSX devs can figure out something.
That's precisely the wrong approach to a problem: if a Windows update has a bug that caused problems to a program that worked fine before, it's Microsoft that should fix it, and in fact that what usually happens when a Windows update cause problems to any 3rd party program/games, and this happens.
We surely can't fix Windows updates, you might have had a point if Windows had major changes that would require ALL developers to fix or change something in their code, but if this happens (an intentional breaking change in Windows, not just a Windows update bug), they alert developers very well in advance, with clear instructions how to deal with this.
But that's not even the point: the "developers" Microsoft should alert about this, are Asobo, not even us, because as far as Simobjects movements are concerned, we only interact with the simulator through Simconnect, it's the simulator that will then eventually interact with Windows so, if because of a Windows KB update, Simconnect has become less responsive or it introduced some extra lag, IF this is not a KB update bug and it CAN be fixed, it can only be fixed by Asobo, if possible.
But that's not even the point too: I DO have KB5031904 installed in Windows 10, and all the multiple videos I posted to show I have no stuttering vehicles, were all made after October 26th, when the KB5031904 came out.
So no, it's not the Windows update that caused a problem per-se, at best it's system-dependent.
I'll try to explain it more clearly, so you should understand that there's not much we can do on our side we haven't done already to prevent this:
Simconnect is like a "metronome" for GSX: EVERY movement or animation that happens in GSX, is based on Simconnect CALLING GSX, not the opposite way around, if Simconnect "forgets" to call GSX for 1 second for any reason (os issue, too many addons, hardware issues, anything), you WILL see all GSX objects stopping for 1 seconds, that's it.
And no, before somebody would suggest "can't you run your own clock instead of relying on Simconnect calling back", this won't change much because, if we reversed the task of who's the "metronome", since in that case GSX would have to always call Simconnect back (to set the variables to animate/move things), even if GSX internal timing was 100% steady, if Simconnect is laggin on getting our data back, it will be exactly the same: if Simconnect is lagging for any reason, there's just nothing we can do to prevent that.
Because, again, it's the sim and Simconnect that are directly related to the relationship with Windows itself and the simulator's own engine. Other than sending commands to Simconnect, and trying not sending them too many at once, there's nothing else we can do, other than HOPING Simconnect is not lagging, and if the lag is caused by a Windows update, there's just nothing we can do, the only ones that can fix that are either Asobo (assuming they CAN), or the Windows team who made the update.
-
I'm with you Umberto.
But it still leaves us with the question, why your (presumably nearly similar) system isn't lagging and ours do. I'd like to find the reason, which would bring us a bit further to solve the issue.

I have been having this issue for a while and today, just for troubleshooting purpouse, I removed all GSX profiles and the problem disappeared. tested at Inibuilds EGLL and Aerosoft EDDM. Put again the profiles in the GSX folder and the problem reappeared. What is the reason of this I don't know, but if this may help I am glad to share my feedback.

That's why a asked in a previous post, how many profiles all of you have installed.
I have to do a bit more testing. But on the first look it seems you got something here. But I had many profiles in my gsx folder (~270). Also possible: it's not about the amount of profiles but the python files (*.py) that come with some profiles these days.

Put again the profiles in the GSX folder and the problem reappeared. What is the reason of this I don't know, but if this may help I am glad to share my feedback.

That's why a asked in a previous post, how many profiles all of you have installed.
I have to do a bit more testing. But on the first look it seems you got something here. But I had many profiles in my gsx folder (~270). Also possible: it's not about the amount of profiles but the python files (*.py) that come with some profiles these days.
Interesting point about the python files. I didn't have time yesterday for further testing, but this evening I am going to try this: I have got the GSX profile for Inibuilds EGLL installed via the Inibuild Manager which installs also a .py file (and with these two installed I have huge stutters), and I want to remove them both and replace with a single GSX profile which I have been using for a long time before installing the Inibuilds one, and see what happens...I will report back

But it still leaves us with the question, why your (presumably nearly similar) system isn't lagging and ours do. I'd like to find the reason, which would bring us a bit further to solve the issue.
You are making it sound as if mine was the only one "not lagging", which clearly can't be the case, otherwise, if mine was a rarity, we would have way more reports by now, not just the exact 12 users who posted in this thread.
So, the real question should be, what's causing this with so few systems? Even assuming only 1 user out of 10 would report it here, it's still a tiny minority of the user base so, either we should assume that most people don't care, or is really not that common.
I have no idea why I don't have stutters and how could I? Usually, you investigate a problem you have but, how do you investigate a problem you don't have?
There's nothing special in my system, it's Windows 10, my installation is not clean by any means, it's full of stuff and hasn't been reinstalled in 2 years at least. The programs that start with MSFS are, in my case:
FSUIPC7
FenixBootstrapper
FSRealistic
Navigraph Simlink
I'm not using an AI traffic product, and I don't have many sceneries installed other than our own.
Maybe you can start with that: try disabling ALL your add-ons, and leave just GSX: do you see a difference?

Well, I understand that you can't reproduce it. But on the other hand you sound like the problem is just a tiny one. Regarding the amount of people that don't care, don't recognize, don't use forums, don't use GSX, 12 people are a lot here. And you should also mention that there are continuously complaints about stuttering in the GSX discord too. So this is not only a minor problem with a few people. I'm trying to be constructive here and find the reason. You comments don't make it easy to stay motivated. It would also help your product, if we would find something. I would appreciate a bit less negativity.
BTW: the only difference (addition) in 3rd party software I'm running - in comparison to you - is FSLTL. Don't run Fenix and FSRealistic and only occasionally run Navigraph Simlink or FBW SimBridge. And as the above poster said: no difference when turning them off.

After some further testing I sadly can't confirm that this fixes it. :(
-

No:
Also completely cleared the community folder but the GSX files, used different locations, different planes - gave Couatl resource priority on task manager, un-installed and re-installed it and GSX - no changes at all.
Also in regards to the post from RogePete, I can only +1 on that one. The current approaches to solve the problem is really unmotivative as a customer. With every claim you kind of feel attacked and the urge to defend yourself and the product. Instead we just want to help and solve an issue together - there is no pointing fingers behind this.
I just want a proper running product! And who could better investigate a product and figure out what is affecting it and holding it back from running smooth than the maker?
In regards to the question how to investigate a problem you don't have: get information from affected customers, ask questions, ask for data, maybe ask for remote access to a affected machine or what so ever - there is so much which could be done instead of just leaning back and defending yourself and your product. Having not understood the problem does also mean you cannot exclude your product from being the issue for sure.
And calling 1 out of 10 users a minority - come on man that's a damn joke and the worst comparison you could have taken. Imagine one of 10 cars delivered out there in the world explode after turning it on for the first time or the state just takes 10% of your daily income because 1 share out of 10 is not much right?... 10% is a huge percentage when it gets down usability and reliability.

How you could have possibly misunderstood that SO BADLY? I'll explain it again:
- Only 12 people have posted here.
- "1 out of 10" means I was generous and assumed that only 1 out of 10 who HAVE THIS PROBLEM are reporting it here, so I'm conceding that we might have about 100 users with this problem.
And 100 users, about several tens of thousands users, it's really a tiny minority, well under 1% of the total user base.

. But I had many profiles in my gsx folder (~270). Also possible: it's not about the amount of profiles but the python files (*.py) that come with some profiles these days.
Airport profiles, no matter if they are .INI or .PY files, are read only when you enter an airport, and never again during operation so no, no matter of many you have, the worse they could do, is they might delay a bit the appearance of the GSX menu.

Do these profiles add lots of VGDS? That's the only thing that, just because a profile loads, could affect performances, because by default, all VGDS are created as static objects, then the one for your parking will get activated when you activate the parking in GSX.
While the static version is highly optimized, with a fairly low visible range, so it should affect fps too much, IT IS an extra Simobject, and we know the total number of Simobjects in the sim can affect Simconnect adversely, and GSX depends completely by Simconnect being responsive so, even if the number might not be high enough to trigger disappearances or generic Simconnect/Navdata errors, it might be enough to cause stuttering, especially on such large airports.
Which is why, a while ago, we added an option in the DETAILS page of the profile, where you can Disable the creation of the static VGDS so, only the one in the active parking will be added, instead of possibly many dozens.
You can try placing the profiles back, but set the option to Disable the static VGDS, restart Couatl there, and see if you see any benefit.
Another thing in the profile that might affect performance, are long passenger walking paths because, the longer the path, the more passengers will be created at once, since they are removed only when the path ends. But of course, this would only be an issues if you ARE on these WALK-IN parking position. Unlike VGDS, which are created when entering the airport (unless you disable them), walk-in paths won't affect performance if you are not in one of those gates and call passengers.

Tried with community folder empty. Only running pmdg 737, FSUIPC and navigraph simlink. Stutters persist. What bothers me the most, apart from all gsx vehicles stuttering, are the pushback trucks stuttering which makes my aircraft stutter when pushing back. I could live with all other vehicles stuttering but not with the one that makes my AC a stutter fest.
-

That's not community empty. Empty means empty. Try GSX and nothing else. PMDG is ok since I always try it first.
And, please clarify if you use Windows 10 or 11, and if you tried my previous suggestion of removing the Windows 8 compatibility flag for the Couatl64_MSFS.EXE.

Yeap, the one that was empty was Community Addon Linker, just tried with empty community now also (moved, aig-aitraffic-effects, aig-aitraffic-modelbehavior, fsltl-traffic-injector, fsuipc-lvar-module, mobiflight-event-module, navigraph-navdata and navigraph-navdata-base to another folder) except PMDG 737 and disabled windows 8 compatibility. Vehicles stutters persist unfortunately. I'm on Windows 11 Pro v.23H2

I haven't you proved right at all, I was replying first and foremost to that, but I keep posting new suggestions to try, to understand what the real cause it.
-
I'm on Windows 11 Pro v.23H2
Alright, so I started the laptop, which runs Windows 11, and tried it at KIAH. Are you seeing something very different that this?
My settings in MSFS:
- Default Ultra profile
- DX12 with Frame generation on (it's a 4090 mobile)
- TAA antialiasing.
- VSync Enabled, 100% monitor rate. The monitor is external and can't do more than 60 hz.
NVidia Control Panel:
- Vsync forced Enabled
- Max fps limited to 58 (tried also 60, no difference)
One thing I changed (long ago) in Windows 11, is the Memory Integrity in the Core isolation page, which is something even Microsoft itself suggest for gaming:
https://support.microsoft.com/en-us/windows/options-to-optimize-gaming-performance-in-windows-11-a255f612-2949-4373-a566-ff6f3f474613
I haven't disabled the Virtual Machine Platform, since it seems to already be running fine as it is now, but you might try that one too.
-
Can u try pushing back with pmdg 737 in Virtual Cockpit captain view and while pushing back turn your head to the left and leave the camera in that still position till it ends pushback?
The way you're moving drone camera in this video makes it harder to see the stutters, but they are there. Your settings are pretty much like mine, with the exception that I only use vsync ON in NVCP, my msfs settings are moderate, fps capped at 100 but tried at 60 in NVCP. I run an RTX4070 and ryzen 7900X3D BTW.
-
The way you're moving drone camera in this video makes it harder to see the stutters, but they are there.
Now I'm worried that what you called "stutter fest", might just be what I consider to be completely minor and inconsequential micro-stuttering.
For example, when a vehicle changes direction or slows down or stops, there is a tiny lag due to the fact new Simconnect commands are sent to command a new heading or a new speed, etc. Those cannot be removed entirely.
I'm sure they would be smoother if we let the sim move them by sending only waypoints but, this method is more imprecise, doesn't support articulated vehicles like baggage trains that have even the front dolly which pivots, and doesn't allow enough precision in positioning which we need to sync animations like the baggage loaders, which need to have the vehicle placed very precisely, so it's not really feasible moving the objects in any other way, which also protect GSX for unforeseen bugs in the sim, like this one:
https://devsupport.flightsimulator.com/t/su14-managed-setdataonsimobject-ai-waypoint-list-can-only-be-used-once/7555
However, some people here swear it "happed after a GSX update", but we have been moving the objects this way for years.
In any case, here's the pushback from the point of view you asked. Sorry for the first 30 seconds, where I had time acceleration 2x enabled (which makes stuttering worse)
-
Thank you for the video and the support. Well, for me those are pretty heavy stutters that weren't present in previous version of your product. You update gsx pro so many times (this is not a critic, the contrary) that I don't recall which version was that was not stuttering like your video and my findings show. I hope you can fix this "micro stutters" for you, "stutter fest" for me, that where not present, let' say in the middle of the year versions.

Exactly, it used to be completely smooth back in September when I last used it. I’m on a gsync monitor and can tell the difference quite well. I mean, if you try to pushback with the default MSFS, you can see how smooth it is while inside the cockpit. It used to be smooth with GSX too back in September. I don’t know what went wrong but I’ve done a complete fresh Windows 11 installation and ran the sim completely vanilla with only GSX in the community folder and Fenix A320 or PMDG 737, still stutters.
I’ve given up on this thing for now. Been using better pushback for weeks now. Can’t stand that stutter mess on pushback right now from GSX.
-
Exactly, it used to be completely smooth back in September when I last used it.
And that's precisely why, in the 2st post of this thread, I posted version 2.7.6 from September:
https://www.fsdreamteam.com/forum/index.php/topic,30676.msg196833.html#msg196833
Nobody that tried it has said it made any difference, clearly proving it's NOT a GSX update, it might be a simulator update, a windows update or a drivers update.
-
I mean, if you try to pushback with the default MSFS, you can see how smooth it is while inside the cockpit.
That's obvious: the default Pushback method is an internal system that doesn't use Simconnect, so it's not affected by anything extra other than the simulator's own code. While everything that connects through Simconnect, is affected by anything in Windows that might affect interprocess communication.
I hope you can fix this "micro stutters" for you, "stutter fest" for me, that where not present, let' say in the middle of the year versions.
It's becoming increasingly difficult trying to follow all these conflicting reports. Somebody swears it was "completely smooth in September", but then I posted a version of the Offline installer from September, and everybody that tried it said it didn't change anything. That should be enough proof that it's not a "change" in GSX but must be a change in something else.
But that's not even the main point, if what I see is clearly minor and inconsequential micro-stuttering, but you see it as "heavy" stutter even in my video so, what kind of investigation into alternative methods to drive animations I could do, when we don't even perceive the results in the same way?
On ONE thing I can agree though: what it looks to me like a minor micro-stutter on my last video, made with Windows 11, I can see it IS a tiny bit worse on Windows 11 than it is on Windows 10 and, in general, Windows 11 for some reasons seems less responsive.
For example, the baggage loader guy that's normally gets attached to the loader vehicle in Windows 10 almost immediately, appears a couple of seconds later in Windows 11. The GSX menu is also slower to appear. This attach is of course made with a Simconnect command and the GSX menu also must wait for the Navdata to arrive before it can list the parking spots or know where you are before it can open so, it seems that for some reason, Simconnect communication is worse on Windows 11. Simconnect communication uses a standard inter-process communication provided by the OS, called "named pipes" so, anything in the OS can possibly affect it.

If this is the case, than that means GSX is not compatible with current Windows or MSFS or Nvidia updates. So basically GSX is the one with the problem. So if I would be a new customer, I would not want to buy GSX because im running the latest windows/MSFS versions.
-
I don’t know about everyone else, but im POSITIVE it was smooth as butter back in September. I’ve done some windows updates and graphics updates since then so don’t really know what caused the issue but all I know is that it wasn’t like that before. If it was Windows or any other update that causes the issue than you would basically have to tell the masses not to update to latest versions of anything cuz it might break GSX. That sounds absurd.
-

I really don't know what you are trying to say now. It's obvious that any issue that could cause a loss in performance in Simconnect would cause a problem to a Simconnect application, or any other problem in the sim/windows/drivers for that matter.
If Simconnect gets less smooth, what EXACTLY are we supposed to do from GSX? Magically make it better? Yes, exactly, expecting this IS absurd.
-
In conclusion, we still have heavy (for me) stutters in all vehicles which weren't present back in mid year.
-
I know this is just a personal preference, but could it even be possible for GSX to just make a program specifically just for pushback? It could be called GSX instead of GSX Pro. I myself don’t care about catering or any of that other stuff. I just want an awesome pushback program. Would that make GSX in that state alone much smoother? I would not mind paying for it again if it was just this.

You just don't want to accept the possibility that what I'm saying it's true and it's NOT something we can control? Is your theory that, because GSX does other things other than pushback, Simconnect would automatically work faster/smoother if we remove the other services? It's not as if we are doing Catering, Passenger, Cargo all at the same time so, extracting the Pushback won't change anything.
Or, are you suggesting we should dumb it down to use the default Pushback system? There are alternatives if you prefer this option, some of them even free.
-
In conclusion, we still have heavy (for me) stutters in all vehicles which weren't present back in mid year.
Well, I guess if Simconnect would improve in a future sim update, not necessarily thanks to actual improvement in the sim but due to a Windows update or a video driver update, it will likely go back as it was (I'm speaking in theory here, because I don't see much difference, it looks smooth enough for me).
Otherwise, how do you explain that nobody who has tried the version from September I posted earlier reported ANY difference (for better or worse)? Not that I wasn't sure of: I KNOW there aren't any differences in the way we drive vehicles and animations, the one and only thing I had a small doubt was the change in the sound engine, and sound is a thing that could potentially cause issues, so not only I posted a version from September after seeing all those comments that "It was fine in September", but also because it was BEFORE switching to the updated sound engine that supports multiple audio channels.
Now, for those not on the GSX Discord channel, I asked a user to make some tests, using different settings of fps locked or not, either in the sim or via nVidia CP. This was to confirm my theory that, being a Simconnect issue, the more strain you put on Simconnect by increasing your fps, the worse it gets.
The user tried it and, guess what, he confirmed my hypothesis (again, not that I wasn't sure of that, but users want to try for themselves before really trusting me, so I give all the instruments they need...), because he saw marked differences between unlocking the fps, locking at 60 and locking it 30, here's his post, you can follow it on Discord if you joined the GSX creators channel:
So I made some testings:
As I'm running with GSYNC, the 3d application's VSYNC is deactivated also meaning that the options in the sim in regards of refresh rate have no effect.
So firstly I pinned the frames to 50 FPS via the NVIDIA Control Panel. The according video can be found here:
https://www.youtube.com/watch?v=jaiPjZO3rG0 (https://www.youtube.com/watch?v=jaiPjZO3rG0)
Result: slight visible difference compared to unlocked framrate, the animations tend to stutter a bit less
Then I pinned the frames to 30 FPS via the NVIDIA Control Panel. The according video can be found here:
https://www.youtube.com/watch?v=BQgaxOMhMgc (https://www.youtube.com/watch?v=BQgaxOMhMgc)
Result: Clear visible difference, the animations are free of any stutters
I deactivated the forced VSYNC in the NVIDIA Control Panel to give the MSFS VSYNC functionality again. In the next video I switched from 100% monitor refresrate (100FPS which are not reached in the SIM) to 50% and 33% which resulted in roughly 50 FPS and 33 FPS. The video can be found here:
https://www.youtube.com/watch?v=yo4Imirx3Eo (https://www.youtube.com/watch?v=yo4Imirx3Eo)
Result: Again the 33 FPS give the best result in smoothness of the GSX animations. The 47FPS via MSFS are comparable with the 50 FPS forced by the NCP - worst is 100% framerate.
The explanation you gave seems to point in the right direction.
What bothers me though:
- Why are not all animations affected at 60 FPS? The animation of the luggage and the loaders walking between the aircraft and the luggage carts are smooth completely independent from the frame rate.
- Why is this happening out of the blue? I've been running on 60 FPS max. since GSX was released for MSFS and haven't had those stutters?
Something must have changed in Sim Connect then I guess. Any chance to find out what has changed and if there might be a workaround? As I heared Asobo themselves are sadly not really having an open ear for issues they create for 3rd Party devs with changes - is that right?
Now the user realized than yes, there IS some truth to what I'm trying to explain, that something must have changed either in the sim itself, or something else has *affected it*, I posted my reply, trying to give extra background, so it would be clear why it won't be easy to improve this from our side, due to the way Simconnect works:
Your tests confirm what I was always sure of: increasing the fps would increase Simconnect traffic, not just GSX, but every other Simconnect application you might be running which is subscribed to the Visual Frame. "Subscribed", means Simconnect is calling back your code at some given frequency so, even if (hypothetically) your code doesn't do anything when called, the sim would *still** have to work more to call all subscribed apps, at each frame. Unfortunately, it's not as if we could decide the calling frequency freely: we only have 4sec, 1sec, 1/6th sec OR Visual Frame, whatever that is. Clearly, 6 fps wouldn't be acceptable for animation, so we are forced to use Visual Frame.
It would be so much better if we could just say "call me back 30 times per second, tops", which would play nicely with the fact most of our animations were tuned to 30 fps, but there isn't such thing and, to make things worse, even if you have the frame rate locked, the real frequency your code gets called back it's jittering *itself* (we obviously measured this), so the real time interval between each call is NOT 33.33 m/sec, even if the frame rate it locked 30, but sometimes it's 31, the next frame it might be 37, etc. That's why we have extra code to COMPENSATE for that, so the animation would at least play always with the same speed, but sometimes Simconnect just "skips a beat" (I think to reduce traffic), so it just don't call you for a frame, without telling you (so our compensating code can't detect it), which turns into a "stutter"
Have a look at this thread about some developers trying to figure this out, and they have far bigger problems than we do, because this jittering is interfering with their INS calculations:
https://devsupport.flightsimulator.com/t/timer-synced-to-flight-model-updates/5239 (https://devsupport.flightsimulator.com/t/timer-synced-to-flight-model-updates/5239)
In FSX they used a workaround because they hacked into the sim and found an undocumented function to tie to the actual sim frame without relying on Simconnect, but this doesn't work anymore.
-
Been away for a while and could not make any further testing, but now I can definitely confirm that the problem occurs ONLY when there is an airport profile in the GSX/MFSF/ folder. With the empty folder everything is silky smooth. I have no idea why this happen, but I can only say that until a few months ago, my profiles folder was full of custom profiles and I had no issues.

Ezio
-
I can definitely confirm it still stutters very much with profile folder totally emptied.
-
@SN737:
Same here: I confirm this has nothing to do with GSX profiles installed or not.

@SN737:

Yeah like I stated before, I even did a complete new windows reinstall and ran the sim completely vanilla other than just having GSX, Fenix A320, and PMDG 737 in the community folder and still the stutters are there.
Haven’t been using GSX for months now so really don’t care anymore. This clearly is an issue with GSX. I even found old reports of people having the same issue on P3D so I’m done with it.

Fact is not affected by GSX profile, in addition to the fact we offered several older versions to try and didn't change anything clearly proves the issue is NOT GSX, but it must be something in SU14 that makes the sim less smooth in calling Simconnect apps.
-
I noticed this issue after updating GSX to 2.8.2 which was before SU14, so it can’t be SU14 which causes these stutters.

And the reason why we posted a much older version to try here:
https://www.fsdreamteam.com/forum/index.php/topic,30676.msg196833.html#msg196833
Was precisely to prove users that are sure it was caused by some GSX update, that it's not. At least, nobody that ever tried 2.7.6 has reported any change, for better or worse.
-
I tried really everything to solve or mitigate the issue.
UNfortunatly nothing to do.
I am so sorry but i had to deinstall and no more use GSX. at least for now.....pity..........i loved it!
-
I tried really everything to solve or mitigate the issue. Unfortunately nothing to do.
It's not clear what you mean by "everything". If you mean the more common suggestions like locking the max fps, it's impossible you won't see ANY benefit. You should at least see some difference but, I am starting to think we are not referring to the same thing and we can't even agree to what "stutters" means.
It would have been helpful to at least know what you are seeing (I guess it must be something HUGE to cause you something as drastic as "Uninstalling GSX"), if you posted a video of it.
It's very well known that SU14 is less smooth than previous versions, and Microsoft acknowledged that as well and even promised some fixes for SU15. Clearly, if the sim is not smooth to begin with, you can't expect GSX won't be affected by that because, as explained so many times, it's not as if we "skip frames" or "miss updates": the whole GSX timing is driven by MSFS itself.
-
Same problem here but only with gsx .
Normal in game trucks and cars in every airport scenery are smooth, no stutters.

Normal in game trucks and cars in every airport scenery are smooth, no stutters.
These vehicles are NOT driven by Simconnect, they use a different system which is internal in the sim and apps can't really use, since they can only communicate through Simconnect (that is, unless you are ok with them doing exactly the same things as default vehicles), GSX vehicles are driven by Simconnect Visual Frame so, if THAT is skipping a beat (that is MSFS doesn't call GSX regularly enough), you will see them stuttering, with just nothing for us to do, other than hoping an update would fix this problem.
Which again, even in the current version, I think it's hardly noticeable so, I start to think (lacking any examples, like videos) we are not really seeing the same thing or, perhaps, because your sim is way more taxed by too many addons calling into Simconnect at the same time, what for me is a micro stutter hardly noticeable, become bigger in some cases.

By any chance has anybody found a culprit or fix to this issue?
-
BINGO!!!
I was able to find a solution on my end.
Ok, I did the following three which I really don't know which one fixed it and I do not dare to change anything to see which one was the culprit for fear of changing it and then not being able to get it working again but here are the things I changed.
1. Disabled Hyperthreading in BIOS. For me this is called SMT(Simultaneous Multi-Threading) since I am on an AMD chip. For intel it is called hyperthreading.
2. Enabled/Forced Resizable BAR with Nvidia Inspector for MSFS.
3. Removed all key binds I had in MSFS settings for my controls and used Spadnext instead.
Can somebody having these GSX stutters test and confirm if changing the above helps you too? Hope it does.
Hopefully this is helpful for the devs as well.

I hope this can get fixed in any way. It's a bit immersion breaking.
Hi, I might have figured out what was causing the issue. It seems that GSX does not play nice with Hyperthreading. At least for me it doesn’t. Can you try disabling hyperthreading or SMT if you are on AMD chip and see if that stops the stuttering for you as well?
-
Hey, thanks for troubleshooting, I'm with 7900X3D and disabled SMT, nothing changed.

Dang. Did you try my other two changes I made? Try resizable bar

I tried with resizable bar but not removing my controllers form msfs and same stutter fest

Hi there,
sorry for the late reply but i had to register first and the activation took some time.
I can confirm the settings you mentioned. Deactivating hyperthreading led to a considerable improvement on my system. The stuttering is completely gone. Ty!

I'm still seeing this issue in p3d only affects PMDG products. I've reinstalled cc libraries and simconnect. The issue has not went away could this be from a windows update?

With "P3D only", you mean you have MSFS as well and you don't have the issue there, or you only have P3D? P3D has less latency on Simconnect than MSFS and, fact you said it only affects PMDG, seems to indicate you are having a completely different issue that is being discussed here.
The thing that is being discussed here, is the GSX vehicles that arrives on the airplane are supposedly not very smooth, and it usually improves by locking the fps. If with "only affects PMDG", maybe you are referring to the AIRPLANE jittering during PUSHBACK? If yes, that's completely different matters, which is related in some way to PMDG custom ground handling and handling of the parking brakes, is somewhat "fighting" with GSX Pushback, which we tried to fix in several ways, like sending fake pushback commands (because PMDG *DOES* recognize default pushback instead), or fake brakes presses, but these are just hacks, the real solution would be PMDG temporarily disable their internal simulation of whatever is fighting against GSX while GSX is pushing, like they surely do when the default pushback is used.

did SU15 with GSX v3.0 fixed this problem? if not does locking the fps fix work for VR users too?
thanks
-
no, all gsx models that moves stutters, even people.

Yes same here every stutter people cars animation ,
On the last mfs developer stream, they talked about this ,
Saying the is a limit of 1000 object per scenery, if there are more it stutters ,
So it's up to the developer to adapt, they will not change the maximum number of object limit .
Forward the video to 17 min and 26 sec.
