Basically all games work, except some multiplayer games with kernel anticheat. You can look up the status of games here:
And specifically the state of multiplayer games with anticheat here (which is a much less favorable % of working games):

I personally wouldn't install any kernel anticheat on a computer that I intend to use for anything important, so I would personally refuse to install the incompatible games even if I was using windows.
"Just trust us, bro! Our security is better than the banks, governments, and major services and we would never let anyone exploit or abuse the gaping hole we're deliberately installing in your security profile! It's just our perfectly secure rootkit that won't ever be used for anything bad!"
It's so weird to me that people just allow this, or even defend it. Game companies should be legally obligated to scale human moderation and curation of multiplayer games, and if you're paying for service that gets moderated and curated, there should be some legal expectation of process - a requirement that the service provider lay out a specific "due process" framework, even if it ends up mediated, that gives a customer legal recourse. Instead, they try to automate everything, which has notoriously indiscriminate collateral damage with no recourse.
If you pour significant chunk of your private time and money into a game, you should be entitled to not arbitrarily lose an account or gameplay progress because some poorly configured naive Bayes classifier decided you did something wrong, without corresponding evidence or recourse to undo bad bans.
For some reason companies are entitled to infinitely expand their reach without concurrently expanding their responsibilities in providing service to individuals. Must be nice.
Take ProtonDB with a grain of salt, Apex Legends still has a Silver rating ("Runs with minor issues") despite being 100% unplayable on Linux for over a year now.
