This game is the reason why a guy [the legendary u/-YoRHa2B-] started working on dxvk, to make this game compatible on linux after it released. Valve hired him and made Proton out of it. The result is the Steam Deck, this remains one of the best games for the SD.
Game runs great on deck, if you don’t mind capping fps at 30, it’ll easily run at close to 10w while looking great.
