Microsoft launched its much anticipated Windows 7 operating system last week to great fanfare. One of the features of Windows 7 is DirectX 11, which is a superset of DirectX 10.1 already used in Vista
Service Pack 2.
Windows Vista introduced the Windows Display Driver Model (WDDM), which allowed new features such as virtualized video memory and scheduling of concurrent graphics contexts. Windows 7 also uses WDDM, albeit a newer version.
