I was reading through Vrchat docs and found this launch option
--disable-amd-stutter-workaround
After disabling it with launch option quest pro over steam link or virtual desktop is no longer stuck on 45fps all the time. This on an 7800x3d and rx 7900 xtx. It hits 90fps very much more often.
Streamed headsets with HMD side reprojection should not need to go half refresh rate unlike displayport to have a good reprojection and i always found it strange it kept getting stuck on 45.
I believe AMD have patches this in drivers since long ago. And this workaround is redundant and now leads to performance loss rather then fixing an issue. It should have been fixed for so long now that not allot people are on that old drivers anymore.
I also did not find any stability issues enabled hardware video decoding with modern drivers.
so you can give that a try aswell if you want to offload some cpu load
--enable-hw-video-decoding
