> Linux is incompatible with client anti-cheat because there is no security boundary that can't be sidestepped with a custom compiled kernel. Windows is Windows, with known APIs and ways to read process memory that can be monitored. Secure boot means only Microsoft's own built kernels can boot and you now have a meaningful security boundary. Monitor what kernel drivers are loaded and you can make it harder for cheaters to find ways in. Sure you can run in a VM, but you can also detect when it happens.

OK I'll just compile a custom ReactOS build that lets me sidestep that boundary.
