The System tab displays the current DirectX version, the computer's hostname, the operating system's version, information on the system BIOS, and other data. The DirectX Files tab displays information about the versions of specific DirectX system files , which are portable executables or dynamic-link libraries (DLLs).
In Direct3D 11, the concept of feature levels has been further expanded to run on most downlevel hardware including Direct3D 9 cards with WDDM drivers.. There are seven feature levels provided by D3D_FEATURE_LEVEL structure; levels 9_1, 9_2 and 9_3 (collectively known as Direct3D 10 Level 9) re-encapsulate various features of popular Direct3D 9 cards conforming to Shader Model 2.0, while ...
Its video memory manager can manipulate video memory with ease, taking full advantage of the blitting and color decompression capabilities of different types of display adapters. Because DirectDraw is a 2D API, it contains commands for 2D rendering and does not support 3D hardware acceleration.
The first version of Direct3D shipped in DirectX 2.0 (June 2, 1996) and DirectX 3.0 (September 26, 1996). Direct3D initially implemented an "immediate mode" 3D API and layered upon it a "retained mode" 3D API. [18] Both types of API were already offered with the second release of Reality Lab before Direct3D was released. [16]
WDDM drivers allow video memory to be virtualized, [6] and video data to be paged out of video memory into system RAM. In case the video memory available turns out to be insufficient to store all the video data and textures, currently unused data is moved out to system RAM or to the disk. When the swapped out data is needed, it is fetched back.
In a console-specific version, DirectX was used as a basis for Microsoft's Xbox, Xbox 360 and Xbox One console API. The API was developed jointly between Microsoft and Nvidia, which developed the custom graphics hardware used by the original Xbox. The Xbox API was similar to DirectX version 8.1, but is non-updateable like other console ...
The Mobility Radeon HD 2300 is a budget product which includes UVD in silica but lacks unified shader architecture and DirectX 10.0/SM 4.0 support, limiting support to DirectX 9.0c/SM 3.0 using the more traditional architecture of the previous generation. A high-end variant, the Mobility Radeon HD 2700, with higher core and memory frequencies ...
Another buffer is allocated in the video memory to represent the DirectX surface, which is used as the texture for the window meshes. The system memory buffer is converted to the DirectX surface separately and kept in sync. This round-about route is required because GDI cannot output directly in DirectX pixel format.
