A flatscreen game. On the Frame it's played on a virtual big screen, best streamed from your Machine over the 6 GHz link.
Analysis — Unholy Heights 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.
Start at the Low/Medium preset + FSR Balanced, then claw back quality: shadows and volumetrics first, textures last (VRAM permitting). If the top settings matter more than native rendering, cloud streaming is the honest answer.
Big screen → the Steam Machine (struggles). Handheld → not a fit for the Deck, or streamed to the Frame on a virtual screen.
