> fool kernel level anti-cheat That's the problem though - if the compatibility layer can fool the anti-cheat then so can actual cheats. Both cheats and compatibility layers do the same thing - modify behaviour. Generally anticheat will take a "blanket" approach and ban or crash by default and whitelist specific types of behaviour. What we ultimately would need would be a kernel level interface/process that the game talks to if it identifies it's running under linux. Which is totally possible to do, linux users specifically would hate it, and it would be a lot of work. Without this you're stuck in userland. Honestly the only realistic hope is the steamdeck becomes a lucrative enough platform for developers to target. Valve has already made sure the popular anti-cheat software supports linux. Valve's stance has been to provide cheat mitigation through other things such as overwatch/trust factor in CSGO (which works well from my experience). VAC itself is actually very primative.
