The new Steam Controller lacks native Windows drivers, making it dependent on the Steam application for functionality. This means it cannot be used effectively with games from other platforms like the Epic Games Store or Xbox Game Pass, as it cannot interface with locked files on Windows 11. Gamers wanting to play titles like Forza Horizon 6 via Game Pass must purchase them directly from Steam to use the controller. While Valve could release standard Windows drivers to address this issue, there is skepticism about their willingness to do so. The gaming community previously developed a tool called GlosSI to enable the original Steam Controller to work with non-Steam applications, and a similar solution may emerge for the new model.
