Following the launch of the Steam Machine , Valve has finally rolled out its compatibility rating system for its living room gaming experience in Steam, with a new UI that shows both Steam Machine and SteamOS compatibility ratings. The new UI is only available in SteamOS in the Steam Deck client or in Big Picture mode, which makes sense, since the update is more than likely targeted around the launch of the Steam Machine. It's unclear if Valve will add a similar SteamOS compatibility indicator to the desktop and web clients, although it does display SteamOS and Steam Deck compatibility in the library on both desktop and the web, so it seems likely that the feature is planned for later.

Currently, the SteamOS and Steam Machine compatibility ratings are hidden in a fly-out window under a UI block called "SteamOS compatibility." The window shows three tabs, for the Steam Deck, Steam Machine, and then general SteamOS, all of which have their own specific compatibility requirements. While the Steam Machine tab shows information relating to the Steam Machine Verified program , the SteamOS tab simply notes whether the game will run on SteamOS via the Proton compatibility layer and whether it needs an internet connection for initial setup or gameplay. The SteamOS rating is likely to apply to most other modern Linux distributions, so it is a welcome addition to Valve's Linux gaming feature set.
