Analysis — Trainz Simulator 12 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.

What to expect

Trainz Simulator 12 has no SteamOS rating yet. A similar game we do rate, Train Sim World 2, lands green on the Steam Machine — a reasonable first guide until this one gets its own verdict.
