Hi just thought I would add this as I have been having issues with motion reprojection using the Hp Reverb G2 but have recently resolved the stuttering this I’m sure will help !
So wanted locked 30fps but all I could get to work is fluctuations in fps up to 45 causing stutters. Fix below, well for me and hope it works for others if you having issue.
Mixed Reality settings under Framerate, I had it set manually to 90Hz so Motion reprojection was halving that to 45fps. So setting it to Let windows decide( then restart pc), means when fps was so low in flight simulator in VR it automatically selected to run at 60Hz then allowing Motion reprojection to run at locked 30fps. (I think that’s how it works, but works for me now so happy days)
Mixed reality headset display settings, experience options = BEST VISUAL QUALITY, display resolution = BEST QUALITY, frame rate to 90Hz.
Open XR developer tool settings, use latest preview OpenXR runtime, custom render scale 100%, Motion reprojection ALWAYS ON.
MAJOR SETTING TO TURN ON OR WONT WORK=Hardware-accelerated GPU scheduling. ( tested with this off and fps all over the place up to 45fps, with on then locked to 30fps=smooth flying).
WINDOWS GAMEMODE= OFF
VARIABLE REFRESH RATE= OFF
Nvidia vsync I have, use the 3d application setting.
Just keep in mind you will then have to adjust the in game graphics settings and render scale so you will always stay above 30fps like as if it wasn’t locked to 30 as any drop even 1 fps below 30 will cause stutter.
In game resolution 70 or 60 depending on, if online or offline flying also depending what you set your graphics settings too. Better of having slightly lower settings or resolution and stay at locked 30 than go below.
Best think being locked at 30fps with reprojection is that you can have higher in game settings & render scale. Some might not like reprojection but I choose artifacts over stuttering any day.
I really hope it helps, as I had given up with VR msfs2020 for a while now, but finally got it to work
I have also contacted Microsoft about getting a manual way to lock motion reprojection rate, like steam vr is now doing and oculus tray tool, they said they have put it forward to developers.
