The Quest 3 works offline with ALVR streaming over a private (non-Internet connected) WiFi network. Together with my 3090 I get 8k @ 120fps with 20ms latency over a WiFi6e dongle. I had to manually install the dkms for the dongle on PopOs, but apart from that it just works. ALVR starts SteamVR and then I use Steam to start the game. Proton seems to use Vulcan for rendering.
