You Can Now Use Your DualSense On Steam
As of a recent update to the Steam Input API, which is the technology that handles external controller functionally, the PS5's DualSense controller, along with most of its advanced features, can now be used in compatible PC games launched from Steam.
Currently, support for the DualSense controller is available only on Steam's public beta client. Like in most similar cases, an initial beta release will allow Valve time to iron out any bugs with PS5 controller support before implementing it into the full version of Steam. Those hoping to test out their DualSense controller on a PC title not yet available for PS5, or even those who managed to secure a PS5 controller but not the console itself, can enable beta updates within their Steam client in order to be granted access to use of their DualSense.
Supported DualSense features include trackpad functionality, control over the LED light that surrounds the trackpad, rumble support, and use of the controller's built-in gyroscope. This allows for mouse-like input via the trackpad and motion controls utilizing the gyroscope, in addition to potential for an enhanced player experience through the controller's light and rumble capabilities. Ultimately, Steam can now support many of the functions that have made the DualSense one of the PS5's biggest advantages over the competition.
Missing at the moment is support for the DualSense's adaptive triggers. In a first for console gaming, certain titles will now alter the sensation of pushing in the PS5 controller's left and right triggers in order to more closely replicate certain in-game moments (though this can be turned off). The adaptive triggers are notably showcased in the critically-acclaimed Astro's Playroom, which comes pre-packaged with every PS5 console.
A lack of support right now, however, doesn't preclude the possibility that Valve will ultimately implement use of the adaptive triggers. Recently, Valve estimated that players choosing a controller over a mouse and keyboard in controller-friendly titles now often reaches upwards of 60%. In short, controller use is growing, thus meaning that Steam's support for different kinds of controllers and their unique functions too only has room to grow. Plus, the PS5 was only just over a week old at the time of Steam's near-full implementation of its controller, allowing Valve plenty of time still to cross the finish line.
A DualSense controller can be connected to a personal computer with either a USB-C cable or over Bluetooth. From there, launching Steam's TV-like Big Picture mode should immediately reflect that the desired input method is a DualSense controller.
