The Microsoft Freeware graphics acceleration
DirectX is a collection of multimedia features for Microsoft Windows. Especially for games, but also for music and video, DirectX is important. Many games charge a certain DirectX version to the minimum requirement. Therefore, you should always install the latest version of DirectX that is available for your version of Windows.
You can easily determine which version is installed on your PC using the DirectX diagnostic program
Press the Windows + R. shortcut key. Tap "dxdiag" and then press the Enter key. If Windows asks if you want to check drivers for a digital signature, click "No"; in the diagnostics program, go to the "System" tab, and you will see the DirectX version at the end of the "System Information" section Code>
Before you install a new version of DirectX, you should upgrade your PC by using Windows Online Update. The graphics adapter must also support the DirectX version. You can find out whether this is the case with the graphics unit installed in your PC by searching for the type designation and the keywords "DirectX version" in the web, eg "GeForce GTX 970 DirectX version". You can find the name of your graphics adapter in the Windows Device Manager
Background: DirectX provides unified interfaces for hardware and software developers. Thanks to the numerous features that are under the bonnet of DirectX, the developers of games must, for example, have much less thought about the graphics adapters on which their game runs. They simply use DirectX features to cast pixels on the screen, play videos and music. On the other hand, hardware manufacturers only have to ensure that their devices support DirectX. Thoughts about the software used by the user with their devices, they have to do so only rarely. Also on Microsoft's game console Xbox the freeware for graphics cards is used. This makes it easier to develop games that run on both Windows and the console.
