SteamOS 3.7 brings Valve’s gaming OS to other handhelds and generic AMD PCs
Ars Technica 2025-05-23
Valve is releasing version 3.7 of SteamOS to the general public, and among the routine updates and changes is a big one: This is the SteamOS release that finally adds official support for some kinds of PC hardware other than Valve's own Steam Deck.
Valve mentions certain specific handhelds as having either "official" or "improved support," including the Asus ROG Ally, the Lenovo Legion Go, and the Lenovo Legion Go S. It also includes directions for configuring the original Legion Go and ROG Ally for SteamOS installation. But Valve says that only the Steam Deck and Legion Go S have fully baked SteamOS support.
The release claims to run on "other AMD powered handhelds" more broadly, implying that most third-party handheld PCs with Ryzen Z1 or Z2-series processors ought to support at least some basic functionality. Other all-AMD desktops and laptops have a decent shot at being supported, too.
