I am playing almost exclusively in linux since 2012 (diablo3 came out, it worked on Linux, i sank an ungodly amount of hours into it.) the only thing that made me reinstall windows was to play counter-strike go on faceit, because their client did not work on linux.

proton made so much, so much easier that it almost became frictionless to play on linux. wine made huge strides before, but it never was so smooth before proton.

what often was a problem where laptops with dedicated and integraded graphics cards, or nvidia cards on rolling release distribution often having issues after kernel updates, which is why i was on fedora for a long time, because there the akmod stuff worked better in my experience.

overall: when it works on the deck its almost guranteed that it runs just as easy on other linux distributions, maybe don't pick a rolling release distro if you have an nvidia card, and most of the time you can forget about the fact, that you are gaming on linux.
