ldwater Posted November 9, 2022 Posted November 9, 2022 Hey, I've recently got a new machine and using my existing headset (reverb G2) I've been hitting a really frustrating issue with VR display stutters uncontrollably. The game will often run perfectly fine with a good solid FPS, everything working normally and then *something* will happen and the VR view will stutter uncontrollably around the head position. I can still play (in a way) as the stutter seems to be around my current head position. Its as if the game gets stuck in a loop trying to find my head position and causes it to act erratically. I've also noticed that the Steam VR button on my controller no longer works once my game gets in this state. The ingame FPS shows no change and my mirrored monitor showing the game normally. Once the session has ended the stutter goes away and everything is back to normal. The *something* I've not been able to isolate. Sometimes it happens after a certain amount of time (10 mins or more) sometimes its when something happens in game (ie, in the AH64, when I get a rotor warning) or when I use the F10 map. It happened in both single player & multiplayer but is never consistent, sometimes I can play entire sessions (1hr +) without any issue and other times it can occur right away and derail my entire session. I've tried the usual suspects, HAGs, changing OpenXR runtime (from WMR to steam & back again), got updates, overclocked, not over clocked, lower graphics settings, higher graphics settings but nothing seems to have resolved it 100% as I can never be sure if or when it occurs. Any ideas? Specs: Intel Core i9 12900KF GeForce RTX 3080 OC 32GB RAM DDR4 3200MHz M2 SSD Windows 11 HP Reverb G2
RLSinCO Posted November 9, 2022 Posted November 9, 2022 There is a known problem with the latest release of SteamVR - have you tried to enroll in the beta program within SteamVR that will install new runtime libraries? This fixed similar problems for me. In fact, I found this solution somewhere else in these forums...
alx_sav Posted November 9, 2022 Posted November 9, 2022 try to lower terrain texture to "low", will reduce ram amount. 32gb ram + 10gb vram not enough. especially apache + syria combination Had similar issues and 64gb ram resolve the issue for me.

I had already set terrain textures to low, but the other texture option to medium. I also tried the new SteamVR beta release and still got the same issue. I seem to get the problem in the maps I own (PG, syria) but when I goto the F10 map the 'shaking' is gone until I go back into the cockpit view. I've reduced my settings down to low again and will see how it goes.

Also Vram usage changed nothing for me. went from 6 GB to maxed out and no difference in frames or smoothness. I have a very similar setup as OP.

ldwater Posted November 10, 2022 Author Posted November 10, 2022 Ok so moving to OpenXR with OpenComposite etc seems to have fixed this issue (ie, I've not encountered the issue yet) but instead my controllers have lost all the previous bindings. Very frustrating!
ldwater Posted November 12, 2022 Author Posted November 12, 2022 64gb didn't help either. Just added another 2x 16gb and still getting the same problem. Really glad OpenXR is a good backup, but losing some utility in SteamVR and my controller functionality is a real pain 1
desolunatic Posted November 18, 2022 Posted November 18, 2022 (edited) I noticed the exact same thing happens to me when playing via Oculus API on my Quest 2. For me the trigger is trying to move my head around in extremely CPU intensive scenarios for example all shadows turned on while spawning in on Enigma or Tempest's blue flash server.

ags Posted November 20, 2022 Posted November 20, 2022 I encountered this "magic random stutter" today as well. OpenXR with a Pimax. Motion smoothing can help a bit. VR, i9, Winwing, TM and VKB. 2, 4, ban, ban, 2
ldwater Posted November 20, 2022 Author Posted November 20, 2022 Using OpenXR I can see some stutter and it seems like its 'trying' to encounter the same problem as before, except with OpenXR it doesn't get stuck in a loop and I just get some stutter that isn't horrible. It does seem to be the game engine itself - as soon as I open the F10 map the stutter is gone, even in SteamVR.
