The anti-cheat will be very unhappy when it performs a bunch of arcane heuristics and determines it’s running in a VM.

Why would that matter? Pretty sure running in a VM doesn't facilitate cheating.

Running a VM gives the parent the ability to read/write arbitrary memory without [even rootkit] anticheat being able to detect, which can facilitate cheating, and therefore can earn you bans. The whole point of the rootkit is that the game can confirm that you don’t have any way to read/write arbitrary memory.
