Title: SLI Flicker is back but cannot fix.
Post by: Matty260191 on July 02, 2019, 01:18:22 am
With the previous version SLI flicker was fixed by disabling RTT but only had issues with the numbers on gates flickering. After the full install of the new version now the Logos on vehicles flicker too and are not fixes by disabling the RTT box. This is a horrific issue that needs resolving.

You weren't supposed to fix the jetway numbers by disabling rtt, that would *remove* the jetway numbers instead. We made an experimental fix explained here:

http://www.fsdreamteam.com/forum/index.php/topic,18864.0.html

But if that doesn't fix it, we don't know how even being to start troubleshooting it. Nobody of us or our testers has SLI.

I have tried what was suggested still to no avail. this did not happen with the previous version the only issues was the gate numbers which i solved but this logo issue is a new one. this may mean reverting to the previous version which s not ideal as finally PMDG was a smooth push back.

have attached files to see if that help you figure this out also. if not how do we go back to the previous version? something is wrong with logos after the update for sure.

This cannot be an SLI issue I just tried it without SLI and this is the result.

There's nothing wrong with the new version, the old version was exactly the same, it's just you didn't noticed that, because this method was used only for jetway numbers and, if you set the "Disable RTT" option, they would disappear entirely so, clearly, something that it's not there cannot possibly flicker.

Both of your videos report an error, so I cannot see what kind of flickering you got.

video links updated. the issue is present with the logo's with rtt on or off in the previous version i only had flashing issues with the gate numbers that why i removed them using disable RTT I never had a single issue with the  logo's flashing. so yes thats a new issue with this version. where can i find the previous version installer please? its not available on the web page any longer.

Maybe I haven't explained myself clearly enough. Yes, the logo are made differently in this version, in the way they are made exactly like the jetway numbers so, the way they work is EXACTLY like in the old version, just that even the logos now use that method, not just the Jetway numbers.

So, if you had flickering with the jetway numbers before, you will have flickering with the logos and this IS caused by SLI.

If that doesn't fix that, I cannot see any other option than having the logos to be entirely disabled, like the jetway numbers, when the "RTT disable" is set.

Your video still doesn't work. Before, it gave an error, now it says "unavailable"

Yes, that's clearly SLI flickering.

There's nothing you can do. We must update the software to be sure that no logo ( or, possibly, a vehicle with a generic non-RTT logo ) is used when rtt is disabled.

The issue at JFK has been already discussed in other threads, and normally would affect FSX users only but, since you disabled RTT, it probably affects you as well. There's already a fix for it on the Live Update.

Ok so Im stuck with this problem then? disable RTT is not doing anything. also I have ran the Live updater several times still JFK has the issue. Like I said i would rather go back to the previous version. is this not possible? what can i actually do at this point? I stream a lot and this just looks real bad.

You are stuck with this problem until we'll fix it. Sorry, but SLI really cause lots of trouble if the software is not made to support it.

You can go back to the old version only if you have an old installer and install it entirely offline.

Just disabled SLI and enabled RTT an magic the textures for the Logo's are back and the KJFK issue is Gone so does that help or did you already know this?

As I've said in my previous post, when you disabled the RTT option, you were getting the same problem as FSX users. Disabling/Enabling RTT also requires a simulator restart.

I am telling you I have just tried the same scenario with SLI disabled and RTT enabled and its works just fine no flicker and it actually loads the textures for Logo's and KJFK has no error when loaded.

To me I take from that that yes SLI causes the Flicker but since I tried with SLI off and RTT disabled and i still got black textures even though the didn't flicker this tells me its SLI causing the flicker but something el;se causing black textures to load for the Logo's is the just the RTT disabled doing that?

So for now my only work around is SLI off and RTT ON.

Of course it works fine. Since the problem IS caused by SLI, if you disable SLI, everything will work and, the "Disable RTT" option should stay on, which is the normal situation.

Maybe it's not clear enough: the reason why there's a "Disable RTT" option is that, on SOME systems (not related to SLI), SOME users reported an API.DLL crash in the Event Viewer AFTER closing the sim.  This was totally harmless but, since some users were worried about it, we added this option so they won't see the error in the Event View anymore, at the cost of losing the Jetway Number.

That didn't had anything to do with SLI, at least initially. If you look other posts of mine, I think to have explicitly said a possible solution for SLI is changing the rttsli parameter in the Couatladdons.ini file, which can be tried, but not Disable RTT, which should always stay on.

My comment about a possible update, was just in case the problem wasn't fixed, not even with SLI disabled!

That's what I always said right from the start: JUST disable SLI, which is what causes the flickering, and use the program in what is the default configuration, which is "Disable RTT" NOT set.

To be honest i have wondered a while about just removing my second card since 2 x 1080's at X8 or i can run one of them no SLI @m x 16 I have other ad-dons with issues with SLi and have learned that SLI doesn't really do much for the Sim. im not 100 % sure but the FPS is the same without SLI and my sim seems smoother due to no alternate card rendering think ill try this for a while see how it goes just a single 1080 should be strong enough.

Post by: virtuali on July 02, 2019, 03:26:28 pm
Yes, SLI is very trick and cause more problems than it's usually worth, because there's some overhead handling it, and there's the additional power request from the PSU. If the software is not really made to support it, is not worth it.

I suggest selling your pair of 1080s, which still have some market, since they are good cards and, if you look for performances, get a single 2080 instead.
