Hi, after many test I found that the only way to fix the problem of FPS drop when switching from VR to 2D is to close the Oculus app. In this way we must re-open Oculus app on PC and Quest Link app within Quest 2 but the problem doesn’t occur.
So use “End process tree” of “OVRServiceLauncher.exe” from “Task Manager”.
This is only a workaround, I see here many, many, many threads about this problem, also with different VR hardware so the problem is from Asobo side. But after years they for sure won’t fix this.
Leave me a feedback
