SteamOS Expands Beyond the Steam Deck: A New Compatibility Label Arrives

Valve is expanding its Linux-based SteamOS beyond the Steam Deck to other handheld PCs like the Asus ROG Ally. To prepare, Steam is introducing a "SteamOS Compatible" label indicating whether a game and its middleware are supported on SteamOS, including game functionality, launcher functionality, and anti-cheat support. Over 18,000 titles will initially be labeled compatible. While Proton technology has greatly improved compatibility, not every Windows game will run flawlessly. This signifies a major step towards broader SteamOS adoption.
