Microsoft Details Direct3D 11.3 & 12 New Rendering Features ()īack at GDC 2014 in March, Microsoft and its hardware partners first announced the next full iteration of the Direct3D API. Nvidia has announced all of its DirectX 11 GPUs will support the latest version.ĭirectX 12 saves on power consumption and boosts FPS () Even AMD, who has their own low-level API named 'Mantle ()', has put their support behind DirectX 12. The API, through working with hardware partners, has lower-level access than ever before which significantly improves CPU utilisation.

If a similar 50% power consumption reduction is possible on the console as found on the Surface Pro 3, then it too could see around a 50% increase in frame rate when DirectX 12 titles start hitting in 2015.Īll of the gains displayed come directly from switching to DirectX 11 to DirectX 12. The situation has been relieved somewhat through the June XDK which unlocked an extra 10% CPU power that was previously reserved for the Kinect peripheral.

Whilst not directly comparable, it could show promise to boosting the Xbox One's prowess.Ĭurrently many game developers are choosing between a 1080p resolution at 30fps, or 900p at 60fps for their Xbox titles. Intel demonstrated this through unlocking the frame rate in their demo to show a 50% increase in FPS (frames per second) using DirectX 12 - despite not drawing any extra power. In a blog post on MSDN, Microsoft claims: "In some cases, DirectX 12 can take a game that’s otherwise unplayable on DirectX 11 without even increasing the power your device consumes!" It does however lead to a much cooler device which as a side-effect allows the GPU to run hotter and faster. Reduced power consumption doesn't, of course, directly relate to increased performance. A key improvement in DirectX 12 is its ability to intuitively share the workload across multiple cores, and the performance gains we are seeing here show this in action. When rendering exactly the same content, DirectX 12's power consumption was impressively over 50% less than its predecessor. To show the improvements, the demo is able to switch between DirectX 11 and 12 at the press of a button whilst locking the frame rate to keep the GPU workload constant. Each asteroid is unique through procedurally-generating a combination of vertices, textures, and constants.
The demonstration renders an asteroid field with 50,000 unique asteroids in it which equates to 50,000 draws per frame. At SIGGRAPH 2014 (), Intel has demonstrated the performance and power benefits of DirectX 12 on a Surface Pro 3 (which uses the company's HD4400 graphics chip.) Listening to the claims of its creator is one thing, but seeing real-world tests on actual hardware is another. Microsoft has been touting the improvements () which DirectX 12 will bring to the table. Um aumento de 50% num teste pesado em primitives e drawcalls parece bastante promissor e em linha com o que já vimos no Mantle.ĭirectX 12 cuts power consumption in half and boosts FPS by 50% () O teste que mostram aqui foi feito claramente para mostrar o que já está feito no DX12. Já começamos a ver o que vem com o DirectX 12 e parece promissor.
