The Witcher 2: Assassins of Kings Enhanced Edition on the Steam Machine
Can the Steam Machine run The Witcher 2: Assassins of Kings Enhanced Edition?
Not reliably — Valve's SteamOS compatibility check flags The Witcher 2: Assassins of Kings Enhanced Edition as Unsupported, and the Steam Machine runs SteamOS.
Red here means a compatibility problem (often anti-cheat or a launcher), not too little GPU power, so lower settings won't fix it. Recommended RAM is 3 GB — comfortably within the Machine's 16 GB.

Cloud streaming runs the game on remote hardware, so SteamOS compatibility stops mattering — if your service carries it. Try cloud gaming (GeForce NOW / Game Pass).

Analysis — The Witcher 2: Assassins of Kings Enhanced Edition on the Steam Machine
The community disagrees with Valve's flag: 141 ProtonDB reports rate it Gold (runs perfectly after tweaks). An Unsupported rating can come down to anti-cheat, a launcher or one mode, so read recent reports for the part you care about.
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.
Steam Deck owners report ~45 fps (1 report). On the Machine it rates red — the step up if you want it on a TV.
