In an upcoming update, Steam will be getting full DualShock 4 support on PC, Valve announced at Steam Dev Days. Jeff Bellinghausen, who works on the Steam Controller team at Valve, said you’ll be able to use the DualShock 4’s touch pad and gyro features:
Soon we will be shipping an update that adds full configurability to controllers other than the Steam Controller. This means that players can pair their PS4 controller directly to their PC and use all the configurability options available to the Steam Controller, including use of the PS4 touch pad and gyro.
Co-Presenter Lars Doucet, an indie developer who worked on Defender’s Quest, added:
Believe it or not, when you use the PS4 Controller through the Steam API, it’s 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.
As for why the DualShock 4 is the first controller to be supported, they explained that, not only is it a high quality controller, but it also has “a lot of overlapping functionality with the Steam Controller,” including the gyro and touch pad. They continued, “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 that’s nice and reliable.”
