Recently, i had to move from nixos to windows against my will simpy because of anti cheats. While i dont game that much, the few games i enjoy playing are all online with some kind of anti cheat. I used to dual boot but i was tired of having to wait for my slow hdd to load windows (i only have one ssd). I literally used linux for everything else but because of anti cheats i am forced to move to windows. I managed to make it a little better by using wsl2 and removing bloatware but it will never be the same as linux
So EAC works, but it works at a different level than it does on windows. EAC does become less secure on both platforms when Linux support is enabled from my understanding. BattleEye, Vanguard and Riots AC don’t work on Linux either, which is a significant portion of major games right now.
I’d argue it is an inherent limitation of Linux, as it’s so open that it’s harder to validate a user isn’t using 3rd party programs to cheat.
