[Help] UE5 gives "The OpenXR runtime requires switching to a different GPU adapter" error with Oculus Rift S on a laptop.

Yes, that it unfortunately a hardware limitation with headsets that use direct mode GPU output. The runtime bypasses the Windows compositor and sets the GPU to output directly to the headset. The interfaces for this are proprietary and there is no way to route the signal between GPUs, so the headset has to be connected to the GPU used for rendering.
