Microsoft launches DirectX 12; boosts efficiency, GPU control
Microsoft today introduced DirectX 12 at the annual Game Developers Conference (GDC) in San Francisco. DirectX 12 is Microsoft's latest version of the graphics API, a leader in the $25 billion PC gaming industry. Nvidia will support the DX12 API on the DX11-class GPUs it has shipped. Compatible cards belong to the Fermi, Kepler and Maxwell architectural families, but cards not strictly adhering to the reference may not be compatible.<br />
<br />
DX12's focus is on enabling an increase in visual richness through a decrease in API-related CPU overhead. DX12 gives the application the ability to directly manage resources and state, and perform necessary synchronization. As a result, developers of applications utilizing the new API can efficiently control the GPU. The DirectX 12 API will span the Xbox One, some tablets, and smartphones for universality.<br />

Anuj Gosalia, development manager of DirectX at Microsoft, described DX12 as the joint effort of hardware vendors, game developers, and his team. Gosalia showed off the new API with a practical demonstration of the Xbox One racing game <em>Forza Motorsport 5</em> running on a PC powered by a high-end Nvidia GeForce Titan Black GPU. In addition, Microsoft's software team has provided a driver to game studios to facilitate further design feedback as well as actual game development.
