The tool includes security and performance updates, along with many new features across all technologies, which can be accessed by applications using the DirectX APIs.

DirectX 11 is a collection of application programming interfaces (APIs) designed by Microsoft to provide developers with a standardized way to access advanced multimedia and gaming features on Windows-based systems. By harnessing the power of DirectX 11, developers can create visually impressive and performance-driven applications across various industries, including gaming, virtual reality, simulation, CAD, and multimedia.

The Microsoft DirectX® End-User Runtime provides updates to 11 and previous versions of Direct X — the core Windows® technology that drives high-speed multimedia and games on the PC.



Direct3D 11 is out and ready for use by your game today to exploit the latest in video hardware features as well as current generation machines. This talk brings you up to speed with the API, offers tips on how to get your renderer up and running, presents key feature overviews, and shows how to deploy your application. Attending this talk is highly recommended if you are attending other app presentations.

Note that the DirectX Runtime (Direct3D, DirectInput, DirectSound) is not part of this package as it is included as part of the Windows operating system, and therefore cannot be installed or uninstalled. Updating the Runtime is achieved by installing the latest Service Pack or obtaining a newer version of Windows PC.
