See previous post:
Isn’t M for performance and L for ultra performance by default?
Ah, sorry. You’re right. Thought I read somewhere that NVIDA was ditchin K alltogether for M, but I got that that wrong. Will edit the post accordingly. Thank you.

I started having stutters in 1.8.9.0 but unsure of the cause as I stayed in the same airport multiple times Airlake, MN thinking it would rule-out scenery loading. I disabled latency killer in the bios and disabled HAGS in Windows. This had little effect and the visual artifacts were still present with DLSS. Today I loaded into the sim and my framerate was significantly down so I re-enabled HAGS. My framerate in the sim in Varjo Desktop view was significantly higher than the previous versions of this beta. It was 185-200 fps when previous versions were 135fps at best. For a brief period VR with vsync 45 enabled was able to maintain 45fps rather than a stuttery 30fps without using OpenXR Toolkit turbo mode. So the sim seemed to run faster than previous versions of the beta. Unfortunately the 45fps vsync dropped to a stuttery 30fps again so I had to enable OpenXR Toolkit turbo mode again and it maintained a solid 45fps.
As for the visual artifacts, I tried flying the ultralight instead of my usual Bonanza. The artifacts were still present but way less distracting. There is a invisible duplicate of all tubes and wires that is offset by about 6" from the visible ones of the fuselage that manifests itself when you move your head around in VR. So every plane exhibits some version of this effect when using any combination of DLSS. The effect still disappears when I disable motion smoothing or keep it activated and switch to using TAA. But DLSS looks way better than TAA now so I’d rather not use it and I can’t get a solid 45 fps with TAA unless I turn the rendering resolution way down
I just turned in-game VR reprojection mode off again and the visual artifacts/warping/rubber-banding in DLSS 4.5 disappears. The image in the headset stutters alot as I move my head but it’s independent of the developer mode fps counter which shows no corresponding stutters. I also notice that the longer the sim runs, the slower the fps becomes although my CPU clock speed remains a constant 5.2 Ghz. Restarting the sim seems to reset the fps back to it’s original higher speed. But this has no effect on the image stutters I see in my headset.
Still no solution in 1.8.10.0.
For me this is a game killer, so no more flights till the next beta release.
I’ve seen no improvement in VR in SU6, just this regression. So as far a I’m concerned they should just undo all the VR mods in this beta and so restore it to the working version I had up to SU5.
I don’ know why this bug is still not feedback-logged. Several people have reported it so it’s not an isolated incident and it is sufficiently severe to cause a major (or in my case terminal) impact on flights.
Still same issues for me in 1.8.10.0. Something in msfs 2024 beta is not playing nicely with motion smoothing. I keep getting display stutters when activating motion smoothing. But if I use Varjo v-sync only, the image stutters go away. I can’t use the sim either. Tried numerous combinations of Windows 11 graphics/Nvidia App/Varjo/and even BIOS settings and nothing resolves it for me. 9800x3d, 64 GB, 2TB m.2, RTX 5090, Varjo XR4
No improvement with the latest beta release 1.8.11.
I don’t normally use repro so I never noticed it. I tried it out today and yes, it has issues especially with foveated rendering on. I do remember that it worked ok with no foveated rendering in SU5. Since getting SU6 I have noticed a decrease in performance. Changing DLSS to the different qualities or TAA or FSR did not significantly change the frame rate. Also foveated rendering didn’t change the frame rate much either. I have noticed about a 10-15 FPS drop in performance in VR since the introduction of SU6. I’ve got a 4090, 7900x3d, 32GB ddr5, and currently still using a Varjo Aero headset. I looked at the usage and noticed that GPU sits at about 60%. No individual CPU core gets hammered. I don’t use Process Lasso either but I am on Win 11. RAM and VRAM also have lots of headroom. Something seems off about SU6.
These are the aspects of VR that Asobo meddled with when releasing SU6:
Does anyone have a good guess which of these would have caused such a change (in my case) in the artefacts apparent when the Depth Reprojection is on. This bug has really stopped me flying.
[ To recap, these artefacts are regions of extreme lag in certain areas around the fuselage of the plane when in the cockpit. In external view, this lag is only visible if I move close to the aircraft and again look along the fuselage. ]
In my case I have communicated with Varjo and they say msfs2024 is more susceptible to this artifact with motion smoothing/reprojection because it doesn’t send motion vectors.
If beta 6 runs slower than 5.1 could it be some additional code meant to fix some other bug that’s forces the sim to run slower?
Thanks for the reply. tbh, in external view the scenery is fine, so I wouldn’t think it’s that SU6 is running slower, but maybe I’m wrong.
What gets me is that I’ve never had any trouble with artefacts like this before, even before I’d managed to tune my (somewhat inadequate) system. I was getting poor resolution and pop-ins which for the most part I managed to tune out, but I’ve never seen anything like these lag effects only affecting defined areas before. And the fact that it’s only in particular, similar areas around all planes is weird. And its only when Depth-Reprojection is on, something I’ve never had trouble with before.
So has one of the changes Asobo made to get better results on PS actually badly affected FS2024 VR performance? To me, this seems the most likely. Or the Quad View change, or what?
Whatever it is, I haven’t even tried a proper flight for weeks now, only a couple of short (about 1 minute) test flights to see if the new releases have corrected the regression. I’m afraid this may well be the end of my flight sim obsession.

That could be it. I know that with any type of repro, the slower the base frame rate is, the more artificing occurs. So maybe you never saw it because you had a good enough frame rate. Also the fact that it doesn’t seem to occur in external views might have more to do with the image you see. In the cockpit, there are lots of sharp edges close to you field of view. Outside, everything is further away so not as much relative movement between foreground and background.
This does not seem to be the case.
Moving my (cockpit) view to outside the aircraft (so the sharp edges are no longer in he frame) I still have the artefacts. Reducing my settings to improve the frame rate has no effect either. My fps in SU6 is comparable to that previously.
I have never seen this effect before SU6. For example, flying the TBM930 has previously always given low frame rates, but never these artefacts. Now, the only way of getting rid of it is to switch off Depth Reprojection, or AMD FSR. In both cases, this introduces performance/quality hits. Switching Foveated Rendering off actually changes the artefacts, but for the worse.
I am convinced Asobo have modified something to cause this. The difference between SU6 and all previous updates is like night and day - previously I never saw it at all, now the only way to get rid of it is to sacrifice my hard-gotten gains in performance/quality.
For me, this is a game-breaker.
I’d like a solution too. I have spent many thousands progressively for a top end computer/headset/and now homebuilt motion platform. For now it seems I’m stuck with using settings discussed in the thread above and not using motion smoothing.
Well this is interesting. I exited the beta because Varjo wanted me to for testing purposes of Varjo Base. For me 5.1 was stuttery and headache inducing but gave Varjo the telemetry they needed. It also ran at about 130 fps in the main menu. I disabled HAGS and game mode because chatGPT suggested this works against my high end system. This did rid me of an annoying image stutter that happened at random in Varjo Base desktop with the sim running in the background.
Today I re-entered the beta and the results are honestly night and day for me. The main menu runs 185-200 fps and flying is smooth as glass 45 fps even while both 5.1 and 1.8.11.0 are streaming scenery or drawing from cache. Even with HAGS and game mode off on 1.8.11.0,the framerate is higher, which didn’t work with earlier beta test versions for some reason.
I forgot about this but sometimes a beta grabs telemetry from PC’s to see what might cause certain issues. That process might slow down the sim slightly. When it’s no longer needed, removing it can make the sim run faster
No resolution of this artifacts problem in SU6 full release, then.
This topic never even received a “feedback-logged” status.
Asobo very obviously are not interested in our PC VR problems, only in getting the Playstation version working.
Having been usable (on PC VR) before SU6, FS2024 VR is now unplayable for me . I have no alternative but to switch to one of the other sims I have in my possession. A very sad day.
The only thing working for me to get rid of artifacts is to turn VR mode off in the VR settings screen. Varjo said I should use motion smoothing enabled if app supports it. When I get a consistent 45 fps, it activates. If that doesn’t work for you then I feel your pain. I think Asobo needs to give the sim the ability to send VR motion vectors.
