Since the most recent updates I have been experiencing really bad stuttering both in desktop and even worse in VR. Originally I had followed a guide for changing the process priority from Normal to High in task manager when this had happened, but since the EAC update I have been unable to change the process priority, getting met with “Permission denied. Unauthorized access” from task manager. I can change other process in task manager still, and I am already set up for administrator permissions.
For VR the only temporary workaround I could get was setting up motion smoothing in Steam VR, which causes the game to lose more frames when activated and has caused some tracking issues for me too. I also have tried unplugging my secondary monitor, but no positive change was noticed. I’ve gone ahead and attached an image of what the performance graph shows before motion smoothing is turned on and with the second monitor disconnected already.
Could I ask how that would help? No other SteamVR or Steam games are having this issue (especially none that already have EAC, like PavlovVR and Dead by Daylight), so I can assume it’s not an EAC problem.
Apparently it doesn’t help. It rather helped people who had problems with the virtual desktop and reinstalling steam vr didn’t help, but reinstalling steam did. If in that case setting priority helped, in the latest developer update developers are going to add such a feature, so we have to wait
Next up is looking into defining process priority as a launch option.
I have also been having this same stuttering issue shortly after EAC was implemented. The only difference is that I’m using an AMD RDNA2 Graphics processor. So far the only thing that has solved the shuddering was my GPU driver completely crashing. I’ve heard that other games that use EAC, such as Elden Ring, share this issue.
I’ve come back to this post because I assumed there was some progress towards this being solved, but recently it’s just been getting much worse. A new problem has come up where my game will just straight up die for upwards of ten minutes when I join a world as each individual avatar loads in, even if it’s with two or four friends and having safety settings on. No matter the size of the avatar, once it reaches 100% my game will freeze for a random duration before actually loading the avatar up. Besides the new problem, my game still has the severe stuttering and also has the new problem mentioned here.
This hasn’t happened to me in any other games. I’ve played Elden Ring and have not experienced any stuttering like in VRChat, if anything the game looks and runs smoother if it goes down to 40 FPS than when VRChat claims to be displaying at 70 FPS from the debug details. I also have never had this problem with Pavlov VR and that too uses EAC.
