Kernel anti-cheat systems are currently the bane of Linux/Steam Deck gaming, haven’t actually proven to be effective at stopping cheaters (see Valorant for an example), and lead to various security concerns from giving 3rd parties full access to your machine to being used to install ransomware and malware.
Windows tried to restrict kernel access years ago, but backed down under pressure from various companies. However Crowdstrike’s outages have shown the sever consequences of leaving kernel access open, and we might finally see kernel access to be cut off.
Have you considered that the reason cheaters have to go hardware level is because kernel level anti-cheats are effective at what they’re supposed to do?
I’ll also ask this question, what do you are the alternative solutions to client side anticheats?
I’m not against client side anti-cheats in general, but kernel level ones are too big of a security risk in my opinion.
The US government is banning apps like tiktok and considering banning DJI drones due to the amount of data they collect and send back to China. Several of the most popular games using kernel anti-cheat are all Chinese owned companies, and the whole point of kernel anti-cheat is that it has full access to your computer (making it hard to hide cheating). I have a strong suspicion that even if Microsoft doesn’t restrict kernel access, we may see government bans on some of these games.
