Nobody can have proof of that, because no such proof can ever exist. How would you ever have a proven correct number of cheaters not detected?

There is evidence kernel level anti cheat can still be bypassed.

Doesn't matter. I will not install a rootkit

Please provide factual evidence, not hearsay. That's % cheaters detected vs % cheaters not detected scaled by the overall player base.

Yeah good luck providing such evidence for any kind of game or anti-cheat.

Personally, I hate kernel level ac and it made me actually stop playing few games and avoid similar ones. Had enough of mere games screwing up with my PC through EAC and EAC ignoring my reports for years.
