Overall, if you are willing to deal with some annoyances, give it a try, it might cover your use cases.
SteamVR is playable, but not at Windows level and rough around the edges. I personally run an Index on a 4080 Super (previously 3080) via the SteamVR runtime. System details in case it matters: Arch Linux Zen kernel, X11 (i3), Nvidia drivers, SteamVR Beta, usually a recent Proton GE version. I remember playing Beat Saber, including modded [1], Until You Fall, Pistol Whip, Raw Data and After the Fall without issues. Non-steam applications outside Steam can also work, I have a launch script that sets up the env vars for Proton, should be easier via Lutris.
I see some problems however. VR itself is not as smooth as it should be, 100% playable, but not as smooth as I remember it ages ago on Windows or using a FOSS VR [4] stack (which has other issues). I don't really use SteamVR home, it sometimes takes a while to load. SteamVR window on the monitor has weird flickering issues, usually I can't get into its settings, likely i3 related. Firmware updates are mostly broken. No (I think) standby for the Lighthouses, I toggle them via Home Assistant and smart plugs.
Shout out to steamtinkerlaunch [2] for making certain settings easier to apply and ProtonDB [3] for tweaks if needed.
