Analysis — Test Subject 901 on the Steam Machine
As a strategy game, this leans on the CPU in dense scenes — the Machine's 6-core Zen 4 is the part to watch in a late-game turn with hundreds of units on the map. Resolution costs little here; simulation/draw-distance settings cost the most.
8 GB of VRAM is comfortable for this title at 1080p; you're unlikely to hit the texture-streaming wall unless you push 1440p with max textures.
Test Subject 901 isn't SteamOS-rated yet. As a strategy game on the Machine's RX 7600-class GPU, plan for a 1080p experience — the 6-core Zen 4 CPU carries the dense scenes, so resolution costs little and simulation/draw-distance settings cost the most. Games like it in this genre — e.g. just a game to test your lQ — land green on the Steam Machine, so expect broadly similar. Own it on a Valve device? Submit your FPS and we'll publish a measured verdict.
Big screen → the Steam Machine (not yet tested). Handheld → not a fit for the Deck, or streamed to the Frame on a virtual screen.
