Sadly a few sim racing games don't run at all and VR is a bit hit and miss (though the Quest3 with either WiVRN or ALVR seems to work well)

Still I'd rather this than deal with daily driving Windows! I'm amazed at how good Gaming on Linux has gotten over the past few years.

If you mostly do singleplayer, sure.

Anything online with anti-cheat is usually broken.
