Prior to DirectX 10, DirectX runtime was designed to be backward compatible with older drivers, meaning that newer versions of the APIs were designed to interoperate with older drivers written against a previous version's DDI. The application programmer had to query the available hardware capabilities using a complex system of "cap bits" each ...
In Direct3D 11, the concept of feature levels has been further expanded to run on most downlevel hardware including Direct3D 9 cards with WDDM drivers.. There are seven feature levels provided by D3D_FEATURE_LEVEL structure; levels 9_1, 9_2 and 9_3 (collectively known as Direct3D 10 Level 9) re-encapsulate various features of popular Direct3D 9 cards conforming to Shader Model 2.0, while ...

DirectPlay Voice was introduced in Windows Me as part of DirectX 7.1 for multiplayer games. [2] It is a voice communications, recording and playback API that allows gamers to use voice chat in games written to take advantage of the API, through a DirectPlay network transport session itself.
The first version of Direct3D shipped in DirectX 2.0 (June 2, 1996) and DirectX 3.0 (September 26, 1996). Direct3D initially implemented an "immediate mode" 3D API and layered upon it a "retained mode" 3D API. [18] Both types of API were already offered with the second release of Reality Lab before Direct3D was released. [16]
Microsoft DirectCompute is an application programming interface (API) that supports running compute kernels on general-purpose computing on graphics processing units on Microsoft's Windows Vista, Windows 7 and later versions.
