Stutter and Stop at 10FPS introduced with World Update 3 still there with 1.14.6.0

Please ignore me. Sorted. Many thanks :+1:

When in flight, hit the ā€œEscapeā€ key, and click on your MS account icon on top-right of the screen. You can pick your server from the list.

Yes, managed to do this. Many thanks for your support :+1:

Latest post from the DEV team. Nothing to report, yet:

and with less than .3% of the users on this forum voting in this thread, when would you expect ā€œthe Teamā€ to report back?

Please, could you give me how to vote for it ?

top of the thread - the blue button left. after voting says voted instead of vote and the counter goes 1 up

there were even much less who complained when yesterday the x-box server totally failed. so this is quite a poor argument for them. but lets hope they finally search for the bug and find a way to correct it. sadly msfs has no debug mode so we cannot send them logs about what is going on when the sim stalls …

Thanks, that’s done

Just posted some examples in another thread, but for the sake of completeness:
Did a flight in UK (to EGSF) and the stutters started. Usually getting 50fps at that location, now I got 15fps due to CoherentGTDraw.
Disabled weather, set daytime, disabled all online functionality (no AI traffic either), nothing changed the CoherentGTDraw value.
Also tried disabling VFR map or ATC window.
Didn’t have this exact issue yet, I only had some occurrences of stutters that came for 20-30s and then got smooth again, this time the performance remained this bad.

Went back to main menu, loaded at the same position with the same setup - 50fps, CoherentGTDraw is negligible.

Setup:
Ryzen 5 3600XT
16GB RAM 3200
RTX 2080 8GB (driver 457.30, default settings in the driver)
MSFS and pagefile are on SSD.

Performance Degradation with 1.14.5.0. Upgrade - Bugs & Issues / Performance, Graphics & CTDs - Microsoft Flight Simulator Forums

That was done too

Same here with the persistant pauses. I don’t get a stutter, I get a full on multi-second pause followed closely by a quicker pause. Everything is unresponsive, but I don’t call it a freeze as the sound and ATC continue as normal. It’s almost as if Active Pause is turning itself on every 30 seconds or so. At these points GPU usage drops to 0%

I’ve gone through all the troubleshooting tips and it makes no difference. It doesn’t happen in every flight, but it is absolutely worse and more repeatable in certain areas. However, even in those areas where it is not happening constantly, I will get at least a 1-2 second pause just before touchdown when landing.

As an aside, since the last update London is now unflyable for me. Along with the persistant stutter the performance drops to 5-8fps in clear skies and 3fps with rain in Live mode.

Please ignore the standard of flying in the video. I was actually my first time trying out one of the jetliners so I happed to be recording it.

I used to have no issue on my 1070 running 4K and high settings. Typically around 30 FPS. Since the update I’ve noticed issues as well, on low settings at 1080p I get roughly 4-6 FPS, 4K on ultra I get the same 4-6 FPS. Seems like nothing I can do to fix this except blink very fast and pretend I can’t see the stutters.

So I seem to have resolved some of the issues by relocating and emptying my community folder. Didn’t have anything weird in there though, just a plane or two, some liveries, and a few free airports. I also noticed I had a bunch of itemized content updates in the game as well. Not sure which fixed it, but now I’m back up and running smoothly, for now at least!

This has been rattling around in my brain since the complaints of stutters and general performance drops began after the update. I have just done a bunch of digging and maybe someone with more experience with the DXGI can wade in here.

It seems that the SwapBuffers call can cause a significant latency in the runtime when combined with certain GPU drivers. I have seen anything from 100ms up to 2 sec pauses in getting a response from the dll. These issues go all the way back to early WDDM drivers (2.0 - up).

Is it possible we are seeing something similar here?

Edit:
The more I think about this the more reasonable it starts to sound. The fact that most users with this affliction have noted a significant drop in both CPU and GPU activity during the stutters would indicate that the program is waiting for something to happen. When the swapBuffers bug occurs the runtime seems to just nod off for a moment. Request goes in… dead air… response comes back and all continues as normal.

I have this issue with a 5900x, 3090, and 32GB 3600 RAM. Game is installed on a 2TB NVME, randomly will drop to 10fps and I can see my CPU utilization plummet.

I see you have the JF Arrow. Make you you turn off the Ipad thing using the little white button on its right side. You’ll see a 10fps increase in frames most likely. Stutters will still be there in certain areas, but just as a head up about the JustFlight ipad thing, it does help to turn it off when its not being actively used.

I know, thanks, and this will be fixed in the update anyway, but it has nothing to do with the performance issues of the sim, they appear on stock aircraft as well.
