To see if the games with anticheat that you want to play are supported on linux, check areweanticheatyet.com they have a pretty huge list of anticheat status where are listed supported, unsupported and denied games.

If your games are on Steam, check ProtonDB.

If not, you’re probably out of luck, but check recent Search Engine results. Best to limit results to around last 6 months, otherwise you’ll probably get outdated information. Only a few bigger non-steam multiplayer shooters work, I can only think of Overwatch right now.

Which games do you play? The only game holding me back was tarkov but I randomly decided to put Linux on one of my drives to see what I could/couldn’t do and I was able to get it working with proton. Probably going to switch over completely soon after I play around with it a bit more
