I've been experimenting recently and while most games run fine and VRR & HDR & Multimonitor somewhat work after some experimenting & tweaks I still have problems with a few games.

Some recent examples would be Noita stuttering and running in slow motion. Getting anything from Ubisoft running (when it does run it runs great though). And modding is very hit & miss.

If Dual Boot with windows (especially if running Bitlocker) wasn't such a PITA I would likely use Linux as my main OS.
