Windows Vista and Later Display Driver Model Architecture
The display driver model architecture for Windows Vista and later (WDDM) is composed of user-mode and kernel-mode parts. The following figure shows the architecture required to support the Windows Vista and later display driver model.
A graphics hardware vendor must supply the user-mode display driver and the display miniport driver. The user-mode display driver is a dynamic-link library (DLL) that is loaded by the Microsoft Direct3D runtime. The display miniport driver communicates with the Microsoft DirectX graphics kernel subsystem. For more information about the user-mode display driver and display miniport driver, see the Windows Vista Display Driver Model Reference.
