Microsoft made a recent update in their blog of their upcoming updates and features. What caught one’s eye is that the confirmation from the company their upcoming next generation console ‘Xbox One’ will not be compatible with AMD Mantle.
Unlike DX11 (and as AMD pointed out), AMD mantle is a low-level API which is made to use as less resources as possible. This will also allow direct access to the GPU and have DX high level shader language compatibility.
Along with DirectX feature, the following was written:
For over 15 years, Direct3D has served as an essential ingredient to deliver cutting-edge 3D graphics in games. During this time, Direct3D has dramatically evolved as a result of deep investments we’ve made in development across our device platforms (Windows, Xbox, and Windows Phone) and continued partnership with industry-leading GPU hardware vendors and game developers. We are very excited that with the launch of Xbox One, we can now bring the latest generation of Direct3D 11 to console. The Xbox One graphics API is “Direct3D 11.x” and the Xbox One hardware provides a superset of Direct3D 11.2 functionality. Other graphics APIs such as OpenGL and AMD’s Mantle are not available on Xbox One.
It was also pointed out that DX11 implementation on the next generation console will make significant enhancements, and the end result will be streamlined and ‘close to metal’ level of runtime performance.
