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.
I get the privacy issue but there’s effectively no non-kernel anticheats on the market. I think VAC doesn’t run in kernel level and CS is known to have a huge cheating issue, so much that competitive CS has spun off into third party provider who among other things uses a kernel level anticheat. You can’t be for client side anticheat and be against kernel anticheat. Non-kernel anticheat simply doesn’t do its job.
I can’t imagine how Microsoft locks down Kernel so that it’s also locked down for cheat developers (because they don’t really care about regulations). If it’s locked for anticheat developers but not for cheat developers then it’s going to end up being a bad time for us.
