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 ...
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]
It is the first version that supports Microsoft DirectX 9.0 and introduces several new features. The graphics tests cover a range of rendering techniques and DirectX 9 features, expanding on a similar system used in 3DMark2001. [9] 3DMark03 does not use a 3rd party engine for any of the tests; light DirectX wrappers are used instead.
Before Direct3D 10, new versions of the API introduced support for new hardware capabilities, however these capabilities were optional and had to be queried with "capability bits" or "caps". Direct3D 10.1 was the first to use a concept of "feature levels" [ 1 ] [ 3 ] [ 6 ] to support both Direct3D 10.0 and 10.1 hardware.
With the release of DirectX version 8.0, DirectDraw was merged into a new package called DirectX Graphics, which extended Direct3D with a few DirectDraw API additions. DirectDraw can still be used by programmers, but they must use older DirectX interfaces (DirectX 7 and below).
In DirectX 7.0 (1999- ), DirectInput added a long-promised feature of seeing individual mice much like individual joysticks, but the feature didn't work with the later released Windows XP, even though as of 2010 it works with Windows 98/Me and DirectX 9. DirectX 8.0 (2000), the last version with major changes, included action mapping and ...
Windows 10 October 2018 Update (Version 1809) Includes WDDM 2.5. [52] Updates to Display driver development in Windows 10, version 1809 include the following features: [53] Shader Model 6.3, adding support for DirectX12 Raytracing (DXR). [54] Raytracing, in order to support hardware-accelerated raytracing in Direct3D 12.
