Valve launches a new SteamOS compatibility system for devices outside Steam Deck to help you know if a game is worth buying

Valve is expanding its Steam Deck Verified programme by introducing a new game compatibility rating system for all SteamOS devices other than Steam Deck. This initiative will help gamers quickly determine if a particular game is supported on their SteamOS device, including the new Lenovo Legion Go S.

Here's What We Know

In its latest announcement, Valve said that the new SteamOS Compatibility system builds on some of the testing already underway for Steam Deck Compatibility. It evaluates key aspects such as game functionality, launchers, and support for anti-cheat systems. If all these components work correctly, the game is marked as "SteamOS Compatible". If not, it is marked as "SteamOS Unsupported".

It should be noted that this assessment does not include performance or controller testing, as different devices may have significantly different characteristics. The rating is intended to help users quickly decide whether a game is worth buying for their SteamOS device.

More than 18,000 games on Steam will already be marked as SteamOS compatible when the system launches. For developers who have already passed the Steam Deck Verified test, no further action is required - the system will automatically convert their results to SteamOS Compatibility. If a game has not been tested yet, it will be queued for a new test, and the results for both Steam Deck and SteamOS will be published simultaneously.

The first device to officially support this system will be the Lenovo Legion Go S, a portable game console on SteamOS that will be released on 25 May 2025. Later, Valve plans to expand support to other devices running the Linux-like SteamOS operating system.

Compatibility information will be available in the Steam Store and Steam client for users of devices running SteamOS, except for Steam Deck. These labels will not be displayed on other platforms.
