Windows Display Driver Model (WDDM) Design Guide
The Windows Display Driver Model (WDDM) is available starting with Windows Vista and is required starting with Windows 8. This section discusses requirements, specifications, and behavior for WDDM drivers.
Note Windows 2000 Display Driver Model (XDDM) and VGA drivers will not compile on Windows 8 and later versions. If display hardware is attached to a Windows 8 computer without a driver that is certified to support WDDM 1.2 or later, the system defaults to running the Microsoft Basic Display Driver.
The following sections describe the Windows Display Driver Model (WDDM):
Note WDDM drivers do not directly use services of the Windows Graphics Device Interface (GDI) engine; therefore, the GDI section is not relevant to writing display drivers for the WDDM driver model.
