SteamOS on a Radeon desktop: what works

SteamOS is the operating system on our Radeon builds when you choose it in the configurator — the same Arch-based, Proton-driven system the Steam Deck and Steam Machine run, on desktop hardware with a full-size graphics card. This page is how we set it up and where its edges are, so you can decide with your eyes open.

Why Radeon specifically

Valve builds SteamOS on AMD’s open-source Linux graphics stack, and every device Valve ships it on is AMD. That is where the testing, the driver work and the fixes go first. NVIDIA cards can run Linux gaming well on other distributions, but SteamOS itself is not built or validated around them — so we only offer SteamOS on our Radeon machines, and that policy tracks Valve’s, not a preference of ours.

How we set it up

Before delivery: current SteamOS image, firmware updates, your Steam account signed in at handover if you want it, and a verification pass that the machine wakes, sleeps, updates and launches from Game Mode the way a console should. You get the desktop mode too — it is a full Linux desktop when you want one. If you ordered dual-boot with Windows, both systems are installed and the switch is demonstrated in your unit’s walkthrough video.

What runs

Most of a Steam library, through Proton — including a long tail of Windows-only titles that never had Linux ports. Valve’s own Deck Verified ratings are the best single signal, and they carry over well to desktop SteamOS on the same graphics stack. Performance on a desktop Radeon card is a different world from a handheld: the GPU that struggles nowhere near exists here.

What does not, honestly

The hard wall is kernel-level anti-cheat. A handful of large competitive titles choose not to support Proton, and no setting on your side changes a publisher’s decision. If your daily game is one of the big anti-cheat holdouts, SteamOS is the wrong OS for you this year and we will say so before you order — check ProtonDB and Are We Anti-Cheat Yet for the current status of the specific titles you play, because this list moves monthly and a static page pretending otherwise would rot. Beyond games: niche peripherals with Windows-only software, and a few streaming apps at full quality, are the other edges worth knowing about.

The honest recommendation

Single-player and co-op library, console-like living-room machine, or you simply prefer Linux: SteamOS is excellent, and it costs nothing on the build. Competitive multiplayer across the big anti-cheat titles: take Windows, or dual-boot. When you configure a Radeon build, tell us what you play in the notes and we will tell you plainly which way to go — before anything is ordered, like everything else here.
