SteamVR works ok, but last I checked it still performs worse than on Windows. If you are feeling adventurous, you can try a FOSS VR stack [1]. It works for Steam games running Proton and when it works it provides better performance. I had some troubles with it, sometimes you need to switch versions or you get some artifacts in games, or some games just don't work at all. Good thing is, switching between FOSS and SteamVR is as simple as launching either first before starting the VR game in Steam.
I guess the Linux VR stack might get a bit of love from Valve for the Steam Frame, so things might improve in the near future.
SteamVR for Linux requires DRM leasing to function and many Linux distros, well... window managers/compositors do not support this. But yes it can work.
