Analysis — Subnautica on the Steam Machine
Adventure games spend their budget on atmosphere rather than speed. On the RX 7600-class GPU, lighting quality and resolution cost the most, so FSR Quality is the trade to make if native looks soft.
Spend the headroom on a 1440p output with FSR Quality; an adventure game shows resolution more than frame-rate.
643 ProtonDB reports rate it Platinum (runs perfectly out of the box), in line with Valve's Deck Verified rating.
Steam lists full controller support, so it plays from the sofa without a keyboard.
Steam Deck owners report ~55 fps (1 report). On the Machine it rates green — the step up if you want it on a TV.
