DirectX is a collection of application programming interfaces (APIs) for handling multimedia, especially game programming and video, on Microsoft platforms. It is a key component of the Windows operating system and is used by many games and other software applications. The latest version of DirectX is 12.
There are several ways to check your DirectX version. One way is to use the DirectX Diagnostic Tool (DXDiag). To do this, press the Windows key + R, type “dxdiag” into the Run dialog box, and then click OK. The DirectX Diagnostic Tool will open and display information about your DirectX version, as well as other system information.
