If they worked to any acceptable level of efficacy then they could be tolerated. They're only tolerated by people who think they work as well as they claim to work (security theater) but anyone who knows about the performance impacts and/or are tech-savvy enough to understand it is a rootkit and potential exploit (that would fully pwn your device) hates them.
Some cheats are getting rather sophisticated now. There's an ever-increasing number of Pi-devices where the cheating is done externally.
That's child's play. The vogue is PCIe devices that sniff draw calls, memory transfers and network activity on the bus.
They're also chosen by users when the game is filled with cheater. Counterstrike 2 is an example of this with players moving to FaceIT and ESEA (with kernel anti cheat) as the higher ranks of official competitive matchmaking are filled with cheaters.
FaceIT works better than normal matchaking, but I am not sure is because is a Kernel level anticheat.
FaceIT only sells one thing, matchmaking, so they have people manually reviewing games. A thing that Valve will never do.
Performance impact is overblown, it was proven that the lost of perf is marginal when implemented properly.
Proven by who and what proof? Because Denuvo is the only one outspoken about how it doesn't impact performance despite all evidence to the contrary and they provide no evidence of their own beyond claiming it doesnt. Then saying they'll prove it doesn't and then backing out of proving it.
