Even gamers nexus’ Steve today said that they’re about to start doing Linux games performance testing soon. It’s happening, y’all, the year of the Linux desktop is upon us. ᕕ(ᐛ)ᕗ
Edit: just wanted to clarify that Steve from GN didn’t precisely say they’re starting to test soon, he said they will start WHEN the steam OS releases and is adopted. Sorry about that.
Anti-cheat systems already have to make changes, since Microsoft have plans to significantly restrict kernel mode access after the major Crowdstrike issues earlier in the year. Kernel mode code is very invasive, difficult to get correct, and can result in major security holes or stability issues if not written correctly.
A bug in userland code may crash that one app. A bug in kernel mode code can (and often does) cause bluescreens, that people blame Microsoft for. I’m sure they’re tired of being blamed for buggy code written by other companies.
Running the anti cheat code in userland will (in theory) make it easier to run on other OSes too.

Yes indeed, I’ve followed that from afar (as I generally mostly play offline, definitely not competitively) so I hope this will be the final missing piece.
I also only play games offline, and these days it’s usually on my Xbox rather than on PC, but I’ve been following this since I’m a software engineer and it’s interesting from a development perspective. Kernel-mode anti-cheat has a lot of similarities with malware/rootkits.
Well put.
