Steam Controller Now Works Outside Steam Thanks to SDL3 Update

Valve's Steam Controller can now be used outside of the Steam platform, thanks to an update to the SDL3 library. The update adds native support for the controller's unique features, including touchpads, haptic feedback, gyroscope controls, grip sensors, and capacitive thumbsticks. Button mappings have also been updated for compatibility with non-Steam games and applications.

SDL3 update enables native support

The SDL3 update enables the Steam Controller to function as a standard input device on any system that supports the SDL library. This means users can take advantage of the controller's advanced hardware without needing Steam running in the background. The update covers all major input methods, making the controller a more versatile option for PC gaming and other software.

In addition to the official SDL3 support, a fan-made application called SteamlessController offers another way to use the Steam Controller without Steam. The app provides similar functionality, allowing users to access the controller's touchpads, gyroscope, and other sensors independently of Valve's platform.

According to reports, the touchpad features in the SDL3 update may still need improvements. The source notes that touchpad functionality reportedly requires further refinement, though specific details were not provided. Valve has not commented on the update or the fan-made app.

The SDL3 update was contributed to the library's repository on GitHub. Valve has not officially announced the change, and the company's plans for future Steam Controller support remain unclear.
