This tutorial will show you how to find the DirectX version you have in Windows 10 and Windows 11.
DirectX is a suite of multimedia technologies required by many Windows games. If your PC doesn't have the right version of DirectX installed (the product box should tell you which one you need), your game might not work properly.
DirectX is a set of components in Windows that allows software, primarily and especially games, to work directly with your video and audio hardware. Games that use DirectX can use multimedia accelerator features built-in to your hardware more efficiently which improves your overall multimedia experience.
