“This document provides an overview of the Windows 8 features that are only enabled by a WDDM v1.2 driver. To take advantage of these features and provide the best experience, WDDM v1.2 is required by all systems shipped with Windows 8.”
In addition to providing a great deal of information on WDDM in Windows 8, the resource also focuses on additional topics, including Direct3D features and requirements, Graphics INF requirements, installation scenarios, and WDDM 1.2 driver enforcement guidelines.
“The WDDM v1.2 feature set includes several new enhancements that improve performance, reliability, and the overall end user experience. Each of these features requires special support from 3rd-party WDDM v1.2 drivers. This section elaborates on what constitutes the WDDM v1.2 feature set,” the company added.
“WDDM v1.2 has both mandatory and optional features. The driver must implement all the mandatory features to claim itself as a “WDDM v1.2 driver”, while the driver can implement any combination (or none) of the optional features. A non WDDM v1.2 driver must report none of the WDDM v1.2 features.”
