Analysis — September 7th on the Steam Machine

CPU vs GPU

In a simulation the tick, not the renderer, sets the pace — a big late-game save with more agents and buildings is what slows the Zen 4 CPU. Graphics presets barely move that; population and map size do.

Room to push

Very high frame-rates buy little in a simulation; spend the headroom on detail, and keep CPU-side settings (population, map size) in check.

On the couch

Steam lists only partial controller support — some menus or modes may still want a mouse, and Steam Input's community layouts are the first thing to try.
