I’ve been gaming exclusively on Linux for more than a decade.

All my games work. Most Steam games work with very little tweaking or none at all.

I occasionally have to apply workarounds for Blizzard games due to a broken Battle.net update, but this doesn’t happen very often and usually only takes a couple days for the community to figure out a workaround. The last few updates have been fine.

Games with certain anti-cheat systems, especially kernel-mode ones, are known not to work. I don’t care, because I wouldn’t allow those to run on my hardware anyway, due to them being invasive and dangerous.

Welcome to the party!
