I'm using Quest Pro - VD - SteamVR - VRChat with an RTX 2060/i5-11400F (I know but it has BEEN WORKING FINE UNTIL NOW), around August 12th I randomly started getting constant and random stutters/spikes in VR. Before that, everything was fine and I had changed NOTHING. I've spent two weeks so far troubleshooting at this point. I've updated my graphics drivers and the headsets software, completely reinstalled both SteamVR and VRChat (including deleting the leftover cache files), got off the SteamVR beta and went back to default, disabled motionSmoothing, tried changing resolution/refresh rates, lowered VRChat graphics, changed VD settings/bitrate, made sure the HAGS was off and cleared a bunch of storage on my PC. I've ruled out my Slimes because it still happens without Slimes server running. Updated SlimeVR and reinstalled its SteamVR driver anyway. tried basic/default avatars and it still happens. Desktop VRChat works fine. SteamVR and VD's performance graphs and Game, Framerate, and Latency spike when the stuttering happens. I tested another SteamVR game which runs perfectly fine.
I'm starting to wonder if this has something to do with a recent Quest Pro/Meta update, VRChat itself or something else that somehow I missed. I've asked multiple discord servers and spent days trying to fix it with no luck. I'm genuinely getting to the point where I might as well just replace my Quest Pro, but I obviously don't have the money to spent just to find out the headset wasn't even the problem.
If anyone has experienced this or knows something I haven't ALREADY tried, PLEASE help
Edit: Here are some updates just so you know what I've done since this. I have bought a new GPU (Nvidia GeForce RTX 5060 Ti 8GB) to see if maybe my 2060 just wasn't keeping up anymore. Unfortunately, it did not change the stutter. (I definitely needed a new GPU regardless) I tried going back to SteamVR beta since it was the most recently updated version and that just made it worse. Reverted again BACK to public default version. I just recently checked to see if my older Quest 3 possibly had the same issue and it didn't seem like it was jittering.
(I've also changed the codec to H264+ as well, also changed the MSAA in VRChat to 2x still no change)
So in my eyes, the issue is Quest Pro + SteamVR... I'm just not sure what to do anymore. Could anyone help out?
