Caesar IVon Valve's SteamOS devices
This 2016 strategy game struggles on the Steam Machine — a steady frame-rate at best, with the top settings out of reach. Cloud streaming is the honest route for max settings. It's flagged Unsupported on the Steam Deck.

Analysis — Caesar IV 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, much like Baldur's Gate 3's Lower City. 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.
