Most anticheat actually works fine on Linux like 99%+ of games with anticheat. It's just a handful of titles which I don't even like anyways, except maybe GTA online that don't work. It's also not a limitation of Linux but an intentional choice made by those developers to disable it on Linux. Their stated reason is because it's easier to edit memory and stuff on Linux, so they rather just ban Linux all together instead of banning cheaters or region locking games where cheating is common, like in China. I think the real reason rockstar does it is because they have big investments in Microsoft or something. Either way I have no desire to support windows, there are plenty of games that I play, nearly all of them in fact, that work just fine on Linux. There is like maybe 2 that won't.
