• 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.
• Added software gyro+accelerometer integration for IMUs without hardware integration. Allows Joystick-Move/D-Pad/Mouse Leaning support for the PS4 gyro input.
• Added New Mode – Joystick Mouse. This is a joystick based mouse control useful for stick based controllers.
• Added controller preference setting for haptics. Haptics can now be globally disabled for a controller or default to the configuration preferences.
• Added support for LED Color setting. Controllers which are capable of setting an LED color can now set this in controller personalization.
• Added LED Brightness/Color controller action binding. The light on the controller can now be changed via a binding. This is useful to mark changes in state such as different action sets or mode shifts, or on start/release press activators for changing while a button is pressed, for example. Light settings are reset to user preference when changing applications/configurations.

It might seem a little overboard to even support the DualShock 4’s lightbar, but it’s definitely a cool feature. This is certainly great news for PC gamers that enjoy using their PlayStation 4 controller on their computer. This further broadens Sony’s PC support, which also includes PlayStation Now and remote play.
