Wddm Info

In the older XPDM model, the GPU was often a "first-come, first-served" resource. WDDM introduces a scheduler that allows multiple applications to submit work to the GPU simultaneously. It preempts tasks to ensure the UI remains responsive, similar to how a CPU scheduler works.

WDDM functions by splitting driver tasks between two main components: In the older XPDM model, the GPU was
