And all of that for something that is worse - software cheats usually get access to more information than just the pixels rendered to the screen. Seeing through solid walls and stuff like that.
You can do DMA cheating if that’s a non-negotiable for you but it is far more expensive. You install a direct memory access (DMA) card on your “clean” machine and flash it with firmware that hides the fact that it’s a DMA card since some rootkit level anticheats will look for that.
The card then sends memory data to a second computer (dirty) which has the cheat software installed but no rootkit anticheat. The dirty computer can then read all the memory it wants, look through walls, shows enemy health, etc. but on a second computer and monitor. Pretty sure there’s hardware to blend both monitor outputs, though most people do two monitors I believe.
