Hey guys, I recently paired a rtx 5080 palit gamerock oc to my system (32 gb of ram, and a ryzen 7 9800x3d) I use Virutal Desktop and H.264+ codec, In vrchat for some reason, from time to time my fps will drop to 45 or lower and stay there constantly until i switch to my desktop and back in vr mode (in VD), i dont know why, my gpu and cpu arent nearly at the % thry could be (also i play on high and 90hz on VD) I updated drivers, i used ddu and reinstalled them and srs dont know what to do anymore, even on my old budget pc, with the same rez ive never gotten these fps locks, and im sure its the games fault because gpu and cpu usage is nowhere near full, sometimes around 50each if not less
What you’re talking about might be “Synchronous Spacewarp” in Virtual Desktop, essentially when your PC can’t push enough FPS for your selected refresh rate it will lock at half of the refresh rate on your PC (45hz being half of 90) and estimate the rest of the frames using the chip on the headset itself.
You can try turning that off under the streaming section inside Virtual Desktop on your headset and see if you notice a difference, it won’t make your FPS any higher but you should be able to see your FPS vary a little more and a difference in smoothness (usually worse when off).
