The employees at Valve have been hard at work for native support for PlayStation 4’s Dualshock 4 controllers on their Steam service. A couple months ago Jeff Bellinghausen of Valve announced on Steam Dev Days that the conversion has been successful.
“Believe it or not, when you use the PS4 Controller through the Steam API, it’s exactly the same as a Steam Controller,” Bellinghausen said. “You make the exact same API calls, you only get actions, not inputs, and the Steam API takes care of everything.”
The Dualshock 4 support has been in the beta phase since, but is now available in the most recent patch on Steam. The patch notes read as follows:
Added Steam Configurator support for PS4 Dual Shock Controller. Enable in Big Picture settings Add/Test Controller settings. When enabled, PS4 controllers will have access to the same sort of customization/configuration support as Steam Controllers, including native API support. PS4 Controllers using this system can map the trackpad, gyro, buttons, etc. to keyboard, mouse, or x-input outputs and can make use of action sets, touch menus, radial menus, and so forth.
Dualshock 4’s are now compatible without any external extra hassle. Bellinghausen has said that there are plans for support of other controllers in the future.
