DirectX is a suite of multimedia technologies developed by Microsoft for use in video games and other multimedia applications. It is a collection of application programming interfaces (APIs) that allow developers to access hardware functions such as graphics, sound, and input devices. DirectX is essential for many modern games and other multimedia applications, and it is important to make sure that you have the latest version installed in order to get the best performance and features.
There are several ways to check the version of DirectX that you have installed on your computer. One way is to use the DirectX Diagnostic Tool. To do this, press the Windows key + R, type “dxdiag” into the Run dialog box, and then press Enter. The DirectX Diagnostic Tool will open and display information about your system, including the version of DirectX that is installed.
