I recommend prepending OXR_VIEWPORT_SCALE_PERCENTAGE=60 to the games launch options
Game plays very well with Proton 10 and XRizer, make sure you use this controller bindings file https://github.com/Raicuparta/nomai-vr/issues/558#issue-3018649448
I am running it via Proton 6.3. It works perfectly well via ALVR. Works on Wivrn, but it is a little more jittery.
Seems to only work with Proton 8. The mod only supports SteamVr and the game does not start with monado. Also the NomaiVR FFR mod crashes the game. To uninstall you need to verify steam files. Once you get in the game the experience is pretty smooth. (Except that reprojection doesn't work in nixos steamvr)
