It is a replacement for the previous Windows 2000 and Windows XP display driver model XDDM/XPDM [3] and is aimed at enabling better performance graphics and new graphics functionality and stability. [2] Display drivers in Windows Vista and Windows 7 can choose to either adhere to WDDM or to XDDM. [4]
In Windows Vista, the Windows Display Driver Model (WDDM) does not support two different display adapters. When using two display adapters, both must use the same WDDM driver. Although Windows Vista still supports XPDM drivers, a WDDM driver is required for the Windows Aero user experience. [54] [55]
Windows Media Center cannot run on startup or on top of other windows because of "new Windows OS requirements and behaviors". [22] [23] Windows Media Player no longer has the Media Guide feature and the DVD tab in the Options menu. [citation needed] Windows 2000 Display Driver Model (XDDM), [24] is discontinued in Windows 8. [25]
A new user-mode driver model called the User-Mode Driver Framework. In Windows Vista, WDDM display drivers have two components, a kernel mode driver (KMD) that is very streamlined, and a user-mode driver that does most of the intense computations. With this model, most of the code is moved out of kernel mode.
Previously, the WDK was known as the Driver Development Kit (DDK) [4] and supported Windows Driver Model (WDM) development. It got its current name when Microsoft released Windows Vista and added the following previously separated tools to the kit: Installable File System Kit (IFS Kit), Driver Test Manager (DTM), though DTM was later renamed and removed from WDK again.
Intel has released production version drivers for 32-bit and 64-bit Windows Vista that enable the Aero graphics. Intel introduced DirectX 10 for the X3100 and X3500 GPUs in the Vista 15.9 drivers in 2008, though any release of DX10 drivers for the X3000 is uncertain. WDDM 1.1 is supported by X3100 but DXVA-HD is not. OpenGL 2.0 support is ...
A mirror driver is a display driver for a virtual device that mirrors the drawing operations of one or more additional physical display devices.. When video mirroring is active, each time the system draws to the primary video device at a location inside the mirrored area, a copy of the draw operation is executed on the mirrored video device in real-time.
Network device drivers for Windows XP use NDIS 5.x and may work with subsequent Windows operating systems, but for performance reasons network device drivers should implement NDIS 6.0 or higher. [8] Similarly, WDDM is the driver model for Windows Vista and up, which replaces XPDM used in graphics drivers.
