DirectX 9 is a version of DirectX that was introduced in December 2002. The most important change was the implementation of High Level Shading Language (HLSL) which made it easier for developers to create 3D graphics and effects. Another new feature is an API which offers Patch-Meshes, common Polygon-Meshes together with improved realtime-animation capabilities.
Versions[edit | edit source]
Microsoft implemented updates into the DirectX 9.0c branch between 2005 and 2010, instead of releasing a new version like 9.0d. This makes it harder to distinguish between 9.0c releases which work on Windows 98 and those which don't, unless you check for the package release date which is also used for this list.

Since DirectX 9.0c, offline installer packages usually follow the name pattern
directx_date_redist.exe, where date is replaced by the month and year of the package's build date, for example
