Windows Display Driver Model

Windows Display Driver Model (WDDM, initially LDDM as Longhorn Display Driver Model and then WVDDM in times of Windows Vista) is the <a href="/facts/Graphic_driver/bcKfPyFt">graphic driver</a> architecture for <a href="/facts/Video_card/bcKfPyFt">video card</a> <a href="/facts/Device_driver/rDYnHU1G">drivers</a> running <a href="/facts/Microsoft_Windows/bwhAhuSL">Microsoft Windows</a> versions beginning with <a href="/facts/Windows_Vista/IASEUCTB">Windows Vista</a>.
It is a replacement for the previous <a href="/facts/Windows_2000/amJIt9gz">Windows 2000</a> and <a href="/facts/Windows_XP/IozrkAYS">Windows XP</a> display driver model XDDM/XPDM and is aimed at enabling better performance graphics and new graphics functionality and stability. <a href="/facts/Display_driver/sUpJQsvH">Display drivers</a> in Windows Vista and <a href="/facts/Windows_7/tldLdbnX">Windows 7</a> can choose to either adhere to WDDM or to XDDM. With the removal of XDDM from <a href="/facts/Windows_8/eRtw96T3">Windows 8</a>, however, WDDM became the only option.
WDDM provides the functionality required to render the desktop and applications using <a href="/facts/Desktop_Window_Manager/Fo1XazIJ">Desktop Window Manager</a>, a <a href="/facts/Compositing_window_manager/Kw5aw1Wc">compositing</a> <a href="/facts/Window_manager/WFRnDBz7">window manager</a> running on top of <a href="/facts/Direct3D/WHJ6DTcv">Direct3D</a>. It also supports new <a href="/facts/DirectX_Graphics_Infrastructure/Qy1cbFDv">DXGI</a> interfaces required for basic device management and creation. The WDDM specification requires at least Direct3D 9-capable video card and the display driver must implement the <a href="/facts/Device_driver/rDYnHU1G">device driver interfaces</a> for the Direct3D 9Ex runtime in order to run legacy Direct3D applications; it may optionally implement runtime interfaces for <a href="/facts/Direct3D_10/WHJ6DTcv">Direct3D 10</a> and higher.
