Windows Vista Display Driver Model (WDDM) Design Guide
Display drivers that run on Windows Vista and later can be written according to either the Windows Display Driver Model (WDDM) or the Windows 2000 Display Driver Model (XDDM).
To take advantage of the latest software and hardware features, you should write your display drivers according to the latest WDDM driver model.
Note 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.
