Proton has been a game changer. Once they get the anti-cheat systems working (and they are making progress), linux will be much more of a valid choice for gaming than it has ever been. I used to do what gaming I couldn't do without on a Windows laptop, but now I do it all on my main linux desktop and haven't booted the laptop for months. Even some of the mod makers are making tools for linux now. It's a completely different world than it was even a few years ago.

There are still games that have problems, but Valve and the wine devs and others are knocking those down one by one. So those 15 people that wanted to switch to linux but couldn't because it couldn't run their games can now do so :)

Similar experience on my end. The only time I find myself booting into my Windows partition is when I play a game with Easy Anti-Cheat.

I have just given up on games with EAC. Much better than constantly switching back and forth, and they’re the exception rather than the rule now.

EAC seems to cause lots of problems even on Windows, unless you have clean install. The thing is very sensitive to any 3rd party programs installed and requires drivers to be up-to-date, breaks some programs by patching system apis etc...

I don't think AC vendors are any inclined to support Linux. ACs are almost always written in a platform-dependent way, which overall hinders the chances of them going to non-Windows systems.

Easy Anti-Cheat (probably the biggest name in anti-cheat right now with games like Apex and Fortnite) actually does support Linux. The issue is even with Linux native anti-cheat, developers are not releasing Linux native games. And getting Windows anti-cheat to work on Linux Wine/Proton is harder to do because of the extra layers in between.
