Analysis — Atomic Heart 2 on the Steam Machine

CPU vs GPU

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.

What to expect

Atomic Heart 2 has no SteamOS rating yet. A similar game we do rate, Atomic Heart, lands green on the Steam Machine — a reasonable first guide until this one gets its own verdict.

On the couch

Steam lists full controller support, so it plays from the sofa without a keyboard.
