OXR_PARALLEL_VIEWS=1 %command%
Running via Envision (Monado, OpenComposite, SteamVR Tracking binaries), I was able to get this working properly. It required 'OXR_PARALLEL_VIEWS=1 %command%' in the launch command to force parallel screen rendering, because of the specific way that Beat Saber handles screen orientation combined with the Valve Index having non-parallel screens.
If you've got wonky views in each eye that don't match as they should - such as the main logo on the main screen being fully glow-y on one eye and half-glowy on another eye or reflections being offset, this might be the fix.
Foundry did not run via Proton in any configration I tried (7-4, GE 7-31, Experimental)
Running it produced no useful error messages, or a cryptic 'Unable to initialize IL2CPP' and closed
Apparently I had a corrupted download, worked fine after re-downloading
Tried my previous install on my windows partition and got the same error. Re-downloaded and was able to successfully launch and play with default Proton 7-4 as well as base system wine.
