Windows 10 just came out today, and it's safe to say that a few of you are already installing it. In tandem with the OS's release, AMD has made available a minor update to its Catalyst drivers, version 15.7.1, which you can download here.
As you can probably guess, the big, new feature is official support for Windows 10, which includes the new DirectX 12 API. All GCN-based Radeons are supported, from the Radeon HD 7000 series onward.
The new Catalysts also include a handful of bug fixes, most notably for Battefield Hardline, Battlefield 4, and Dirt Rally. For more information, check out the release notes.
