Have you tried removing the nvidia HD audio & nv Virtual Audio devices in device manager. Also turns of hardware acceralted shcedualing in windows “grpahics”. Hags works for dirt rally 2, but not in msfs. It causes stuttering, at least for me.
Is it possible that you are sitting too near your play area boundary and accidentally triggering the chaperone? I saw that happening for someone in DCS and it took them a while to work out what was happening.
Similiar to all you folks… great 2d performance… which I do not use, and stuttery low FPS in VR, on high settings mind you.
Curious, bad performance always in a dozen of test flights, less once and I had a square with green numbers in front haha, and good fps and smooth like FS20 or better maybe. It promises in the future I think.

I guess VR is completelly broken or just total coincidence wether it works or not. What a disgrace!
Especially considering Asobo and also mainly Jörg Neumann constantly braging how proud there are of the new sim and how much they care about VR.

Yup this is my experience, I’ll be rocking along at 40-60fps depending on settings using at the time and I’ve tested them all at this point and it’ll just suddenly drop to 28-30fps, then after a little, it snaps right back to normal, then I’ll lower settings for the next flight and it’ll be perfect, so I think I’ve solved it only for then the next flight for it to happen again.
Also the weirdest part for me is if I’m flying in a place like LA or other photogrammetry, super detailed cities/areas, it has never happened.
But when flying in the countryside or in and around small towns is where it happens the most.
I’ve tried all settings I’ve reinstalled the sim and nothing has changed. I’ve seen a stream where something very similar has happened in 2d, so at this point just have to wait for patches.
One of the last times it happened I landed, it was at around 50fps, I missed the taxi turn off so did a U-turn, just as I completed the turn the fps went straight to 28 and was like this till I went to parking and as soon as I stopped, even before shutting down, it snapped back to just over 50fps.
So yea out ideas at this stage.
System is 4090, 5800x3d, 64 gigs of ram. Crystal light.
And during these drop GPU utilisation drops into the 70’s-80’s usually.

Also a lot of CDT when switching from / out the VR mode. The in-game panels are tiny sometimes (EFB / steps for career mode), sometimes we are misplaced in the aircraft, the position is reset every time we go to the main menu, the yaw axis cockpit does not work in VR, we loose the possibility of click the controls, the toolbar does not shoes up whatever you do, etc etc. This software has not been tested at all… I am really frustrated that a company can release that type of software. Also the new setting engines: impossinble to see the axis effect as in FS2020 in order to calibrate them, impossible to see what is currently assigned as control for a given plane, a mess… The FS2020 settings were awaful, but they succeedd to make it worse.

It is wild how those things went downhill so so much. Even just refueling and putting weight in the airplane SUCKS now. I hate the new interface.
I’m using a Quest 3 and in most games I get smoother / higher fps results with link cable. However, for some reason I always have stutters and judders even at the lowest possible gfx setting in 2024.
Virtual desktop in 2024 is significantly smoother for me. Unfortunately the VD hand tracking is a bit too laggy for my liking.
edit - just wanted to add that in msfs2024, for both link cable and VD, turning on Turbo Mode within OXRToolkit improves the stutters on my system. It also makes a big improvement in DCS

The VR performance is awful but not just that… You have to lower EVERYTHING and turn ABSOLUTELY EVERY RTX EFFECT OFF in order to achieve 40fps in DLSS QUALITY, which means 0.66% of the native resolution of High (pimax play) or 100% (steamvr). Right now, ghosting everywhere… textures from FSX and a totally killed immersion. In 2020 we were fine but we were promised with new features like a native autofps and new effects, even they said that the performance was going to be better.
NONE OF THIS HAD HAPPENED.

I have the same problem with 3070 in 2020. Was hoping maybe 2024 fixes it but doesn’t sound like it up to now. What helped me to at least make it happen less often is disabling E-Cores in BIOS.
I’m experiencing the exact same issue, but only after updating to the latest Nvidia drivers.
I’ve been playing MSFS2024 in VR using the Reverb G2 for about 40 hours with very consistent FPS. I have an RTX 3080 and was running medium-to-high settings with great performance.
Everything worked well until I followed a couple of YouTube videos to optimize my VR settings. I updated the Nvidia drivers today, and since then, I’ve had the same issues described by the OP.
I did some tests and noticed that my FPS remains steady at 34 during free flights, but in career mode missions, I encounter the same behavior as the OP.
Interestingly, if I lower my 2D settings to very low (e.g., 1920x1080/low settings), it significantly improves VR performance, which seems odd.
When my VR performance drops to a poor 16 FPS and I switch back to 2D, the frame rate is still terrible (around 5-6 FPS, as described by the OP). However, if I close the WMR software, the 2D frame rate immediately returns to 60 FPS.
I’m completely lost at this point. I was considering upgrading to an RTX 4090, but now I’m hesitant since everything worked perfectly for the last 5 days—before I updated the Nvidia drivers.
I too am having a similar issue.

Everything runs fine and smooth until I try to fly the C-17 or the A400. Then I get the 3 fps and lag to the point I turn my head and 30 seconds later the screen moves to catch up. If I end that flight and load up to any other aircraft, everything is smooth again.
One thing I learned recently was that having Texture Supersampling on 2x2 or higher can slam your VRAM on some aircraft, that could be what’s happening here. Some larger aircraft for sure have ridiculous VRAM usage. Same thing with having the Texture Resolution on Ultra.
Run out of VRAM = Slideshow time
Also seems like a VRAM usage problem This used to be a problem with FS2020, where the 2D settings were hogging VRAM and affecting VR once you switched.
Seems like we might have to do the good ol’ 2D trash settings, so we can load in VR with the settings we want.
Similar experience with my Pico4 over Virtual Desktop… Only solution is to restart the PC. It looks like a memory leak. Once the sim got hit by it… it’s done.
I’m going to speculate that with so much streamed from the cloud, that MS can change settings on the fly and we don’t know when, we just see the results?
That is my worry, that visuals are culled bandwidth wise to improve performance and vr really take a hit

Exactly the same problem for me.
I tinkered for hours, tried everything I could think of to no avail, except a precious few times where it works great and then, no more. All I got was mostly nausea inducing slide shows.
Config:
AMD 5800X, 32 GB DDR4 RAM,
3080 GPU
Reverb G2,
Gigabit ethernet in a big metropolitan area, the PC is wired to fast and recent router
Latest DLSS file, latest nvidia driver
I use Open XR toolkit,
I have zero mods installed
Windows 10
I will try downgrading my driver, my 2D settings, my texture supersampling (though I know I turned it off during my tests), checking my chaperone, removing the HD audio drivers and virtual audio devices in device manager and turn off hardware accelerated scheduling in windows graphics and report back.
@RestiveGuitar91, do you remember which Nvidia driver version you were using when it was working fine? Anyone here using older drivers with success and if so, which version?
