I switched to Ubuntu for my gaming PC over a year ago and from my Steam library of hundreds of games so far I only found maybe 1 or 2 that did not work on Linux, but worked on Windows. All the others work flawlessly*

* there is one caveat to that though - if you have a VR headset, then there are many people reporting performance issues on Linux with those headsets. And personally I also find VR performance subpar on Linux (although it still improved in the last year).
