WDDM
Definition
Windows Display Driver Model, the Windows graphics-driver architecture.
Detailed explanation
WDDM means Windows Display Driver Model, the architecture connecting graphics drivers with DirectX, the Desktop Window Manager, memory management, and GPU scheduling. WDDM versions add operating-system capabilities and require corresponding driver support. The reported WDDM level is not the same as a GPU marketing generation. The model separates user-mode graphics translation from kernel scheduling, memory management, and display miniport responsibilities. Later revisions introduced GPU preemption, hardware scheduling, protected content, and new presentation capabilities, with support jointly determined by Windows build and driver.
