Kieshi as a mentioned before, the fix is quite complex, so we need more time to work on it. We hope to have it in place in version 13.16. We are doing our best to do it as fast as possible.
Honestly i cant understand what is so complex ... I still use steam version of DeoVR 8.55 that is almost 3 years old version and it works perfectly smooth on Quest 3 , Win10 (latest VirtualDesktop version) , RTX 40xx and all kind of 8K VR180 vids ... So even if you just roll back that old DeoVR version it will works fine ...
