See my reply above; Monado is also an option and is something you can realistically actually use productively these days. Its performance is much superior to SteamVR's vrcompositor IME and having a socket-activated OXR runtime where you don't have to faff with a shitty proprietary GUI app that breaks every few weeks is really nice.

Note that you only need to patch AMDGPU, which is a module. Much cheaper to build than a full kernel.

ALVR reportedly works and AFAUI it actually uses Monado but I don't have any experience with that software as I use an Index.

I don't stream and don't see why you'd want to as latency is about the last thing you want in VR. Ig warping makes rotation tolerable insofar as to not make you immediately puke from the delay? Never tried tbh because I'd rather strap a laptop on my back.

Delay in which movement/inputs? As mentioned, head rotation will be fine regardless of FPS or latencies because rotational warping is capable of compensating for any delay – even infinite.

Translational movement and any controller movement are the critical parts. If you barely move laterally due to sliding in-game movent, it wouldn't be apparent.
