Take a look at Riot Games's Valorant, featuring Vanguard, one of the most precise and intrusive (it had ring 0 kernel access, the highest level of access the operating system can asign) anti-cheat systems ever developed
All the above issues were caused because valorant their anti cheat DISABABLED third party programs that were controlling their hardware like fans etc. The victims of that were minor. That said, there were ALOT of teething problems, valorant their AC was a terrible release but that doesn't make every other AC terrible aswell.
Wondering what is your estimated cost for good AC? Wondering where GF should find money for good AC?
