The PlayStation 4 controller will have basic PC functionality. Sony’s Worldwide Studios honcho Shuhei Yoshida confirmed on Twitter that the DualShock 4’s basic button and analog stick controls will work on PC just by plugging it in the USB port. When asked if the controller would be recognized at the API level as a DualShock 4 by Windows after launch, Yoshida replied that people will have to “wait for [the] field report” for more details.
Sony will likely need to write additional software to enable the Touchpad and other features on the controller that would not be recognized natively. If that is done, then it’s likely that the PS4 controller could stand toe-to-toe with the Xbox One controller or even the newly revealed Steam controller for PC gaming.
