Kernel level anti-cheat is a no go for me. Some people have talked about companies releasing patched kernels for Linux to allow them to exist but I genuinely think if you do that to your system you’re asking for it when inevitably some vulnerability is detected and it breaks your physical machine.

I already don’t trust games and appreciate being able to run them in Lutris as a Flatpak where at least they can be run somewhat sandboxed, in addition to revoking their network privileges so they can’t phone home and spy on me. If a game essentially wants to run a rootkit, hard pass.
