Rust has a long, rocky will-they-or-won't-they history when it comes to official support for both Proton and Linux, and with a new Steam Machine on the way it's no surprise to see those conversations popping up again. Valve's cute little cube will run SteamOS and use Proton—a compatibility layer to make Windows games play nice with Linux—but you can't play official Rust using it.
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.
