Hello!
When I use my VR headset in the simulator, I experience a stuttering effect, similar to a low FPS situation. After checking the FPS display, I noticed that it consistently showed good values, around 25-40 FPS. However, this stuttering issue only occurs when I move my head. It almost seems as if the simulator briefly shifts my viewpoint to a slightly different location below the intended position and then quickly brings it back. This happens everywhere in the sim not just in the plane. It’s really not smooth and really annoying. Please help!

It might be your framerate falls below your refresh rate (or a division of). Try lowering the VR resolution first to see if it helps when looking around. If it does then you’ll need to either lower settings or resolution to get a better framerate that fits your headset refresh rate.
The other thing it could be is bad tracking, which can be helped by cleaning the on-board cameras (in case smudged etc) or if outside in tracking, checking your base stations etc. If it happens just in MSFS then it’s likely performance though.
What refresh are you running? VR always stutters if it’s not exactly or exactly half your refresh rate. Try to get to 45fps (assuming 90hz). Maybe 1/3 works too, but I can’t deal with 30fps in VR (it’s OK on consoles).
I got tip from an youtuber that I should use minimum refresh rate. So I guess 70Hz. And I forgot to mention that I use the Oculus Quest 2.
The Q2 does 72hz. If you can’t reach that oi fps, lock it to 36fps.
I don’t think the performance is the problem here. When I move my head just a bit, it causes the screen to move down and up. Looking straight and flying doesn’t affect me as much as when I my head. As I said my FPS stays the same at 25-40 fps.
I think in VR the higher refresh rate is better. It means that the headset can latch on to a frame faster than a lower refresh rate. I am finding that 40fps is not smooth enough for VR, so I am using DLSS Performance these days. Although I keep some settings on Ultra, I typically turn down texture supersampling, shadow maps, terrain shadows, contact shadows, AO, and reflections.
VR issues need a process to step through to find where the problem is.
With any game there is game movement and headset movement. In MSFS, it is the aircraft movement, so if there is stuttering when the aircraft moves, it is MSFS or your VR launcher, such as SteamVR.
You should be able while stationary, move the headset and it is smooth, otherwise it is the program that sends the image to your headset.
I use Virtual Desktop, so for your problem that would be program with the issue for me. I could test this to see if the VR image on the monitor has the same issue.
Of course, it can be a group effort to ruin your day, but there will be a weak link.

OK that sounds strange. In any case, 25-40fps will never look smooth in VR at 90hz.
It depends on personal preference and perception. I’m perfectly happy with the smoothness at 35-45 FPS with Pimax Crystal running at 90Hz. I can bring FPS higher by reducing settings or resolution, but I don’t do this as I like the high crispness of the image.
If Motion Smoothing called also Motion Reprojection was enabled in my previous headset - Reverb G2, I was fully satisfied with the smoothness at 30 FPS, it was even acceptable to me at 23 FPS (1/4 of 90Hz at which R2 runs).
I tested to see if the same thing happened on my screen and it didn’t. On the screen it works great, just a little laggy.
I’ll try to explain the problem better. When I move my head in any state of the flight it’s like some places in the aircraft turns into waves and in some places it just lags. As I said this doesn’t happen on the pc screen.
Thanks for all the answers!
