An upcoming Steam update will "add full configurability to controllers other than the Steam controller," starting with the popular PlayStation controller.
Using the controller is "exactly the same as a Steam Controller. You make the exact same API calls, you only get actions, not inputs, and the Steam API takes care of everything."
"It's also got a gyro and a touchpad, so it's got a lot of overlapping functionality with the Steam Controller," adds Jeff Bellinghausen of Valve "Also, existing native support for the PS4 controller on the PC is a bit weak; in this case Steam itself is communicating directly with the device so everything [is] nice and reliable."
Support for other controllers is on the way, as well, adds the company.
