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 ...
Direct3D 9Ex, in conjunction with DirectX 9 class WDDM drivers allows graphics memory to be virtualized and paged out to system memory, allows graphics operations to be interrupted and scheduled and allow DirectX surfaces to be shared across processes. [41] Direct3D 9Ex was previously known as version 1.0 of Windows Graphics Foundation (WGF).
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 ...
Windows Display Driver Model (WDDM, [1] initially LDDM as Longhorn Display Driver Model and then WVDDM in times of Windows Vista) is the graphic driver architecture for video card drivers running Microsoft Windows versions beginning with Windows Vista.
Microsoft Windows is the name of several families of computer software operating systems created by Microsoft. Microsoft first introduced an operating environment named Windows in November 1985 as an add-on to MS-DOS in response to the growing interest in graphical user interfaces (GUIs).
As of today, NVIDIA's GPUs officially support Microsoft's DirectX 12 Ultimate framework.
DirectX Graphics Infrastructure (DXGI) [1] is a user-mode component of Microsoft Windows (for Windows Vista and above) which provides a mapping between particular graphics APIs such as Direct3D 10.0 and above (known in DXGI parlance as producers) and the graphics kernel, which in turn interfaces with the user-mode Windows Display Driver Model driver.
Microsoft DirectX, a set of standard gaming APIs, stopped being updated on Windows 95 at version 8.0a. [17] It also stopped being updated on Windows 98 and Me after the release of Windows Vista in 2006, making DirectX 9.0c the last version of DirectX to support these operating systems.
