As of November 2008, Microsoft is delivering the first taste of DirectX 11 for Windows 7 for download. A release aimed at developers, The November 2008 DirectX Software Development Kit, brings to the table the successor of Direct3D 10.1, namely Direct3D 11. In the SDK package, the Redmond company is offering a technical preview of Direct3D 11, but also the adjacent components and tools. Backwards compatible, content developed for Direct3D 11 hardware will also be compatible with earlier products supporting Direct3D 10 and 10.1 (in Vista SP1). Via the Windows 7 Developer Guide, Microsoft provides an insight into the new features made available by Direct3D 11.
“Geometry and high-order surfaces can now be tessellated to support scalable, dynamic content in patch and subdivision surface representations. To make good use of the parallel processing power available from multiple CPU cores, multithreading increases the number of potential rendering calls per frame by distributing the application, runtime, and driver calls across multiple cores. In addition, resource creation and management has been optimized for multithreaded use, enabling more efficient dynamic texture management for streaming,” Microsoft revealed. Read More»

With Windows 7 pre-Beta Build 6801 out of Redmond, it was only natural that DirectX 11 would follow. And this is precisely what happened. Having served Milestone 3 Build of the next iteration of the Windows client, Microsoft is also moving forward with the graphics technology included by default with the operating system. The transition from Vista to Windows 7 is synonymous with the evolution from DirectX 10.1 (in Vista SP1) to DirectX 11. At this point in time, the first taste of the next version of the DirectX suite of multimedia application programming interfaces (APIs), namely DirectX 11, is available for download via the November 2008 DirectX Software Development Kit.
“Included in the November 2008 DirectX SDK is a technical preview of Direct3D 11 and associated components and tools. Direct3D 11 is an update to Direct3D 10.1 enabling new hardware features as well as improving the breadth of configurations supported by Direct3D. As such, Direct3D 11 enables developers to create applications and games that work on Direct3D 10, Direct3D 10.1, and Direct3D 11 hardware when it becomes available. With the addition of WARP and Direct3D 10 Level 9, Direct3D 10.1 and Direct3D 11 have the ability to target fast software rasterization and Direct3D 9 hardware,” Microsoft revealed. Read More»

Microsoft has already indicated through the voice of Anantha Kancherla, manager of Windows desktop and graphics technologies, that DirectX 11 would be at the vanguard of the upcoming general purpose graphics processing (GPGPU) revolution. However, the real details have only been shared with developers and not the general public. From the recent Microsoft GameFest 2008 conference, details related to the evolution of DirectX 11 managed to slip through, but of course not through the company’s official channels, which are keeping mum in relation to the next generation of its graphics technology. Ignacio Castaño, NVIDIA Technology Developer, indicated that end users are in for a treat via the Tessellation of Displaced Subdivision Surfaces in DX11 presentation.
The Tessellation enhancements cooking for DirectX 11 will enable developers to offer what Castaño referred to as “unprecedented visuals”, namely “highly detailed characters and realistic animation”. But of course there is more to it, in the line of performing “expensive computations at lower frequency: realistic animation: blend shapes, morph targets, etc. and physics, collision detection, soft body dynamics, etc.”. DirectX 11 will ensure that the users will benefit from an increased level of detail while fewer resources will be consumed because of compression features. Read More»
