The latest plea for official Proton support started on Reddit, where Scout339v2 shared their screenshot of Rust running “on a server with EAC disabled to show that the game already works perfectly on Linux.” Disabling Easy Anti-Cheat (EAC) is the key factor here, and part of a broader conversation where Facepunch and its Linux/Proton userbase don’t see eye-to-eye.
While it’s true Rust runs on Proton, you can’t join official servers, and most unofficial servers, with EAC disabled. Facepunch considered changing its stance in 2022 when the Steam Deck launched, but didn’t end up introducing official Proton support. COO Alistair McFarlane said at the time that Linux is “safer for cheat developers,” and that trying to support EAC on another platform could reduce the team’s ability to support Windows.
I think the way that CS does it is really the best one. Prevent the simple cheats, record games and let people handle the edge cases based on reports and suspicious activity.
While I agree that this is usually enough, you end up with the issue that with volume the process becomes bogged down to the point of inefficiency. The best bet is to implement this system with a much more robust server side cheat detection, and ideally not send occult information or recieve bad information from the clients to minimize the damage that can be done with a cheat.
I didn’t know CS did this, but yeah, at a high level, that’s how I’d address it, too. It’s probably not a solution that scales super well due to the manual review required, and I know that game has a reputation of people still being annoyed by cheaters, but it might be the best we can do without being very invasive, like the ring 0 stuff.
