The latest update to Steam brings improved controller functionality for the DualShock 4. While Sony brought official DualShock 4 PC support when they released the DualShock 4 USB adapter and launched PS Now on PC, Steam still hadn't gotten around to playing nice with it until now. Valve had previously announced adding DualShock 4 support to Steam and today they've followed through.
Once your Steam client has updated to the latest version, you'll find that the DualShock 4 can be mapped using the same interface that the Steam Controller uses. You can map the DualShock 4's face buttons and joysticks, and you even have the ability to map the controller's trackpad and internal gyroscope to any keyboard, x-input, or mouse action.
The update also brings the ability to simulate a mouse device using "joystick mouse" support. You can also now change LED brightness and colors of supported devices via the Steam client, and set controller configurations to load only when a particular user is playing with a particular controller.
The usual bug fixes and other updates were also part of the latest update. It's great to see Steam opening more venues of hardware support, and as time goes on, I'm sure the service will make using a variety of control options even more intuitive and user-friendly.
