Analysis — It Lurks Below on the Steam Machine

CPU vs GPU

As a RPG, this leans on the CPU in dense scenes — the Machine's 6-core Zen 4 is the part to watch in a densely-populated city district. Resolution costs little here; simulation/draw-distance settings cost the most.

8 GB VRAM

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.

Room to push

It already clears 60 at high. Spend the headroom on a higher refresh target or 1440p + FSR Quality rather than maxing settings that barely move image quality.

Which Valve device

Big screen → the Steam Machine (runs great). Handheld → Playable on the Deck with tweaks, or streamed to the Frame on a virtual screen.
