Touch Down Shutters 1-2 sec apause

[virtuali]

so what is the point, that using 3.5.6 stopps the stutter in many cases or increasing TLOD when using 3.5.8?

As I've said, we had reports from several users that even using 3.5.6 didn't fix that, so I think it's must be a coincidence that only worked for some users, because the only meaningful change we had in 3.5.7 was the automatic restart after takeoff, and that is gone in the current version, and we added extra optimization we never had before so, the current hotfixed 3.5.8 has the lightest possible load (as far as communication with Simconnect is involved) on the sim during the landing step we ever had in a long time.

Increasing the LOD seems a more likely explanation but, clearly, it cannot possibly have anything to do with a GSX change or update, since it has no control whatsoever on the LOD switching process, the one and only app that can do that, is AutoFPS, because it access MSFS memory directly.

As I also said in my last post, a GSX restart just before landing might in fact cause this, that's why I provided with information to affected user to verify if this is what happened, by checking the auto-restarter log.

I updated again to 3.5.8 and are now on a testflight from EDDK to EDDP. Same as last days. But this time with TLOD 50 in the MSFS settings and without auto FPS. Will report back.

[Yoda_1976]

Just landed. autoFPS is not used or active. TLOD 50. Stutter is back. Short, under a second, but it is there with latest 3.5.8. It has to do with the TLOD. I am not an expert in terms of software. So i can`t imagine why it is so.

I can confirm that I don't use AutoFPS, and my TLOD is always at 150. The only way to correct the stutter for me was to rollback to 3.5.6.

I had this issue also and is gone on 3.5.6. However I only noticed it on PMDG planes....3.5.8 didnt give the pause when using the Fenix A320. Can everyone clarify they were using a PMDG product? I used the 737-700/800 when getting the freeze.

*CONFIRMED*

Fenix has NO pause at touchdown on 3.5.8
PMDG HAS large pause at touchdown on  3.5.8
I-fly MAX HAS large pause at touchdown on 3.5.8

Hopefully I havent added mud to water

What is really worrying, instead, was the report GSX crashed on landing (or likely before). This shouldn't happen, but if it did, an automatic restart will likely cause stuttering, because during a restart there's lots of file access required, so we should probably verify if this was the case.

Checking the auto-restarter log at %APPDATA%\Virtuali\couatl64_boot.log file might tell if there was a restart on (or moments before) landing, since it comes with timestamps.

Unfortunately, i had done two more flights after the one where Couatl64 crashed, so the couatl64_boot.log file is only showing the most recent flight, where i didn't encounter a crash (just the freeze on landing though it wasn't very long on that flight).  There is nothing in there between the messages at 1:02am when i started the sim to 2:57am when i was already at the gate at my arrival (might even be when i exited the sim).  If it happens to crash again at landing though, i will be sure to note the time and grab that info out of there.

I have had the freeze with the Fenix A320.  To date, i've had it with the Fenix A320, FSS E170/175, iFly 737-MAX8, and the PMDG 737-700/800/900.  The length of the freeze has been varying though, anywhere from barely a second to now up to like 10 seconds...  I have not tried to roll back to GSX v3.5.6, but i have found, like others here discovered, that changing all services to "0" except for the jetway did clear up the issue completely on the only plane i ended up trying it on (PMDG 737-900).  I have no idea about why the length of the freeze varies though; however if Yoda_1976 determined the TLOD can affect the length of the freeze, maybe it has to do with what is visible of the airport at touchdown?  That's just a guess though.

Unfortunately, might be a couple of days before i can get back to MSFS, so i won't have anything more to add to this for a bit.

Lots of valuable input here now 👍

So far, we have ruled out the issue is caused by AutoFPS or a specific aircraft.

Since the length of the pause/freeze can vary from under a second to well over 10 seconds, it does seem a parameter which can differ is involved. I don't think TLOD nor OLOD are though based on how I've seen the length of the freeze vary even when those values are always the same on touchdown.

Fenix has NO pause at touchdown on 3.5.8
PMDG HAS large pause at touchdown on  3.5.8
I-fly MAX HAS large pause at touchdown on 3.5.8

This is very interesting info: we had users reporting freezes up to 30 seconds with the Fenix, so I always tried to use that (assuming it was a worse case), I'll surely try more with PMDG and iFly.

I have had them in the past on the Fenix, but this was on past iterations of both GSX and the Fenix. Specificly now the freeze does not occur unitil I use I-fly/PMDG aircraft, although the length was different. Ive also set all of them to have services set to 0 in the aircraft.cfg as per above minus the jetway to make it even. But sadly yes Unlinking GSX or Using 3.5.6 get rid of the issue.

We are trying a completely different approach here:

- Update GSX to the latest version, 3.5.8

- Remove this folder:

\Addon Manager\MSFS\fsdreamteam-gsx-world-of-jetways\LivingWorld_Config

- Use the free MSFS Layout Generator here to refresh the layout.json for the fsdreamteam-gsx-world-of-jetways package.

https://flightsim.to/file/93859/msfs-layout-generator

- ONLY if you use MSFS 2020: you need to perform an extra step, and it's entering the GSX Config page in the installer, and Disable ALL Airport Services, if you don't do this step, the test is not meaningful.

To confirm the test has been done correctly, you should see the *default* Asobo Pushback when starting on any gate (before you call GSX, after that it will removed).

i am also having this issue. except normally about 15 seconds. I downloaded the old version given in this thread, i believe 3.5.6? and it works completely fine again!!! so frustrating

LARGE freezes on the .8 new version - in both the FENIX and PMDG

[virtuali]

I downloaded the old version given in this thread, i believe 3.5.6? and it works completely fine again!!!

Have you tried the solution I posted above ?

Hi, I tested your solution, all was fine, now I see a new version.
What is the procedure with the new build 3.5.9 with MSFS2020. Airport service must be still disable?

Thanks

No, that was just to confirm the problem, now it's all fixed.

[WebMaximus]

No, that was just to confirm the problem, now it's all fixed.

So there's now a 3.5.9 where the issue is fixed?

Would be interesting to hear what the true culprit was after all troubleshooting that has been going on here.
