Because if I can just load my own driver before you load your anti-cheat driver it significantly lowers the difficulty of defeating the anti-cheat. Whoever gets into ring0 (or below) first usually 'wins'.

So for example Valorant's anti-cheat leverages a hypervisor which is always-on, and then an additional client which runs when you launch the game.

The situation is similar with the ESEA counter-strike client.

I just refuse to play games with measures like that. Especially given the fact ESEA got caught deploying a bitcoin miner with their client.

These games always have cheaters anyway, so what am I giving up all that privacy and security for?
