If you play in Linux assuming this game even runs on Linux. Good chance they will ban you from running this game on that OS. They could allow it but most companies see Linux as a minority and will mostly willing to take the hit of blanket banning the whole OS. I guess Steamdecks would be out of question now. Another is security risk this kind of anti cheat tend to be invasive they have access to your kernel, the part of the OS that has access to everything on your system. If that thing is compromised good chance you’ll be affected also if you have that in your system. Think of something like crowdstrike issue.
That’s a lot of hate from you there. I can almost smell it in my room.
