Analysis — Atomic Heart on the Steam Machine
RPGs swing between light dungeons and busy hub towns, and the towns are the Zen 4 CPU's real test. If the frame-rate dips there, cut NPC density and draw distance before touching resolution.
Spend the headroom on image quality — 1440p output with FSR Quality — rather than settings that barely move the picture.
130 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.
