Be sure to use an updated proton (later than 5.13-6) and turn off FSYNC. This way the game will run great.
With Proton up to 5.13-6, the game crashes usually at the start. There's a bug report for that at https://github.com/ValveSoftware/Proton/issues/4614 -- if you have a later proton, chances are it is already fixed. I was able to run the game with the following launch options: "PROTON_NO_FSYNC=1 %command", using Proton Experimental as of March 5, 2021.
Played with a Valve Index VR kit.

It crashes shortly after the first game scene and takes SteamVR down with it, needing a reboot to settle.
