Windows Display Driver Model (WDDM) is a graphics driver architecture for graphics cards running Microsoft Windows, starting with Windows Vista. WDDM is a replacement for the Windows XP video driver architecture (XDDM/XPDM) and aims to improve graphics performance, new functionality and stability.
WDDM provides the functionality needed to visualize the desktop and applications using Desktop Manager, a composite window manager that runs on top of Direct3D.
WDDM also supports the new DXGI (DirectX Graphics Infrastructure) interfaces required for basic device creation and management operations. The WDDM specification requires a graphics card that supports at least Direct3D 9 and must implement interfaces up to Direct3D 9 for compatibility with older Direct3D applications, and WDDM can optionally implement interfaces for Direct3D 10/10.1 and above.
