Ich glaube es geht hier um ein emuliertes Playstation Spiel. Dem ist der offline Modus von Steam egal.

Isn't the whole point of anti-cheat to survey the computer? If you aren't getting anything new, then why even use a kernel-level anticheat?

Because the one thing they want to find, cheat software, can hide if it's running in kernel mode and the anti cheat isn't.
