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.
