The main issue: When my pc is focused on VRchat, the performance of all other applications almost freeze. Steamvr dashboard refreshes a frame per second, responds sometimes 5 seconds after a click on anything in the dashboard. Virtual desktop monotors don’t show. XRS overlay wont respond.
I must unfocus VRC so that I can access other applications. Sometimes other applications crash (including the steamVR dashboard) when VRC is focused.
It depends on the world usually. It is not consistent. VRC is the only VR title I have this issue with.
Thats all I know, I would play unfocused if it didn’t tank my frames down about 50-70%. Anyone found a solution to this?
I’m running a windows 11 system thats medium to high end (tldr: 3080 12 gig, ryzen 9 9900x)
I use virtual desktop to play VR with a quest 3.
I never encountered this issue before but, had experienced something like it. Ever since I’ve upgraded over to a Ryzen 7 7800X3D, I had an issue where changing the render resolution and/or playing heavy intense GPU games and GPU workload causes my system to either freeze, go unresponsive but takes every second for my mouse to update and keyboard to go unresponsive, or hard-freeze. I couldn’t figure out what was causing it until I suspected that my RAM was the issue. You see, I had enabled the XMP/DOCP profile thinking it would be stable out of the box. Turns out, the higher frequency and tight timings weren’t completely stable with the 7800X3D’s memory controller.
The reason why this happens is: XMP/DOCP profiles often push memory right up to the edge of what the memory controller, motherboard, and RAM sticks can reliably handle. Even if the kit is rated for, say, 6000 MHz and listed on the QVL, every CPU’s IMC (integrated memory controller) is a little different. With workloads like high-intensity VR rendering or GPU-heavy games, and heavy GPU workload, the system is already under a lot of stress, so any slight instability in RAM timings or voltage will show up as freezes, input lag, or complete hard locks.
Once I disabled XMP and let the RAM fall back to JEDEC defaults, all the freezing and stuttering disappeared instantly. Later, I was able to get it stable by lowering the frequency slightly (from 6000MHZ to 5600MHZ) and bumping voltages in BIOS. Realizing that the “out of the box” advertised XMP settings weren’t guaranteed stable. Ever since adjusting those settings, I haven’t run into the random lockups or freezes.
