Valve has announced that the DualShock 4 will be the first controller to be natively supported by Steam.
Gaining native support, customizable controller figurations and support for the DS4’s gyro and touchpad, players will no longer have to use external software to use Sony’s controller during gameplay.
You make the exact same API calls, you only get actions, not inputs, and the Steam API takes care of everything,” presenter Lars Doucet stated as he and Jeff Bellinghausen presented a live demo of the controller’s touchpad functioning as a mouse in Bethesda’s Doom. Other third party controllers will also follow suit, though at a later date.
A release date for the update has yet to be announced.
