Topic on Controller talk:DualShock 4

What is the reason this controller is often not supported by games over BT when at the same time it is supported over wired connection? Thanks.

The way Windows work with devices is that each device have a unique hardware ID that both identify its vendor as well as product / device model. Windows uses this to match the device to an applicable driver.

Games work the same way, and basically identify recognizable controllers through their unique hardware ID, and this is where the unsupported nature comes from.

You see, when the DualShock 4 is connected using Bluetooth (or even while using the Wireless Adapter), this unique hardware ID differs somehow, and if games aren't developed to take that into account they won't support the controller over the other connections.

Basically, during development the development team _only_ tested and included support for the controller while it was connected using a cable, and didn't test and implement support for the controller when it was e.g. connected through Bluetooth.
