Valve Introduces SteamOS Compatibility Ratings for Third-Party Devices

Valve is set to enhance the gaming experience on SteamOS devices by introducing a new compatibility rating system. This initiative aims to clarify which games are fully supported on third-party SteamOS devices, such as the upcoming Lenovo Legion Go S handheld gaming PC.

The new SteamOS Compatibility rating will appear exclusively on SteamOS devices that are not Steam Decks. It will indicate whether a game is “SteamOS Compatible” or “SteamOS Unsupported” based on its support for all features, including anti-cheat tools, ensuring users know if the game will function properly on their device.

Importantly, Valve clarifies that this rating does not assess performance or input quality, as hardware variations among third-party devices can affect these factors. Instead, the rating focuses on compatibility and feature support.

The compatibility data is automatically generated from existing Steam Deck verification results, meaning developers do not need to perform additional testing or certification steps for their games to receive a SteamOS Compatibility rating. This automation is expected to mark over 18,000 Steam titles as compatible from the outset.

The Lenovo Legion Go S will be the first handheld gaming PC to run SteamOS instead of Windows, making this compatibility rating system a critical tool for gamers and developers alike. It helps ensure a smoother transition and better user experience on new hardware powered by Valve’s gaming-focused operating system.

Broader Significance for the Gaming Industry

This compatibility rating system represents a significant step toward expanding the SteamOS ecosystem beyond Valve’s own hardware. By providing clear compatibility signals, Valve empowers gamers to confidently purchase and play games on a wider range of devices without worrying about technical issues or missing features.

For developers, this system reduces the burden of additional testing and certification, allowing them to focus on optimizing performance and gameplay. It also encourages broader adoption of SteamOS, potentially increasing the market for games compatible with this platform.

As SteamOS gains traction on new hardware like the Legion Go S, Valve’s compatibility rating system will be a key resource for ensuring a seamless gaming experience and fostering a vibrant ecosystem of supported titles.
