Deck: Not ratedOnline broken · Easy Anti-Cheat

Broken. Currently not working on Linux, though it may be fixable by the developer or anti-cheat vendor.

Setup & launch options

No working launch option exists. Forcing the anti-cheat to load under Proton is not recommended and can lead to account bans.

General guidance only. Per-game launch options aren't part of the upstream dataset, so follow the community notes for game-specific steps.
