Microsoft also stressed that DirectX 12 for mobile will increase power efficiency and allow for easier porting between console, PC and mobile. Microsoft claimed that DirectX 12 will also have more developed support for multiple GPUs - potentially including the ability for applications to use both CPU/GPU hybrid chipsets like Intel's Haswell and dedicated GPUs simultaneously. With DirectX 12, Microsoft is targeting a broader number of platforms - Nvidia suggested that many video cards running DirectX 11 are already compatible with DirectX 12, including the company's Fermi, Kepler and Maxwell series of cards.įorza Motorsport 5 developer Turn 10 Studios showed off a version of the racing game running with Direct3D 12 on a PC powered by an Nvidia GeForce Titan Black, and according to the studio, bringing the title to DirectX 12 allowed it to run at a locked 60 frames per second. This can provide a significant theoretical improvement to game performance, and is similar in many regards to AMD's Mantle technology, which has only been available to AMD GPU-owning consumers in Battlefield 4 so far. In 3DMark benchmarks, Microsoft estimates as much as a 50 percent improvement in CPU performance, though real-world results will likely vary. Microsoft is also providing new tools for developers to access "lower-level" functionality of hardware, eliminating some of the performance hits caused by DirectX's communication between a game engine and system hardware. DirectX 12 seeks to enhance graphics efficiency for modern games by allowing developers to more easily spread tasks across multi-core CPUs, while reducing CPU "bottlenecks" that can reduce theoretical performance from dedicated video hardware. Microsoft and partners from Nvidia, AMD, Intel and Qualcomm showed off the next version of the DirectX gaming API, DirectX 12, at the 2014 Game Developers Conference today.Īccording to Microsoft officials, DirectX 12 will offer major improvements for developers across all Microsoft platforms: Windows, Xbox One and Windows mobile OSes.
