DirectX 9

DirectX 9.0c includes support for Pixel Shader and Vertex Shader 3.0, along with many new features across all technologies, which can be accessed by applications using DirectX.
DirectX 9 Features include:
  • Multi-Threading: The ability to scale across multi-core CPUs will enable developers to take greater advantage of the power within multi-core CPUs. This results in faster framerates for games, while still supporting the increased visual detailing.
  • DirectCompute: Developers can utilize the power of discrete graphics cards to accelerate both gaming and non-gaming applications. This improves graphics, while also enabling players to accelerate everyday tasks, like video editing, on their Windows 7 PC.
Windows 7 comes with a newer version of DirectX but is fully compatible with all of the new features of DirectX 9.0c. Additionally, in order to take advantage of the features of DirectX, you must ensure that you have installed a DirectX compliant video card.
If you're wanting an even newer version, DirectX 10 is also available. This version is the download of the redistributable version. That means it may be included in software packages or just simply used freely by anyone wishing to update their DirectX version on Windows XP or Windows 7 (32-bit).
This package contains the DirectX 9.0c installer for Windows XP, the installer for Windows 7 and is compatible with the DirectX 9 redistributable from February 2010 and June 2010. This web installer package works with DirectX 9 graphics devices with WDDM 1.0 or higher drivers. In case you run into issues when installing this package, you may have an older video card that is not compatible with DirectX 9.0c.
The DirectX 9 SDK is also available for download from this site (use the search function).
Please note: If you are using Windows 7 and a game or other programs requires you to have DirectX 9.0c compatible video or audio driver installed, you should check to see whether there is a patch available for the game or program you have installed. In some cases, simply installing updated drivers for your video or audio card solves the problem. If updating drivers doesn't help, running the program in compatibility mode may..
