These days, instead of having to search for your card model between a list of potentially hundreds of listed models, you instead only have to ensure your graphics card is compatible with that DirectX version.Īs a side note, DirectX was created by Microsoft. Game developers would write to use the DirectX libraries, as would graphics card manufacturers. A full stop in the wrong place could crash your entire system.ĭirectX was created as a means to combat this obvious problem. Computers can be incredibly difficult to work with, even with the slightest inconsistency. And if the developers decided they did not want to deliberately add the support, too bad.

You would have to go through a small list of cards and try and find your exact model number. In the early days of computer gaming, you would need to ensure that your graphic card was actually listed as a supported card.

A set of cards from the same manufacturer might speak almost the same language, but it will not be exact, like two people speaking Chinese except with different dialects. To elaborate on why we need it, every computer graphic card speaks a different language. That does not account for developer ability, of course. Newer versions of DirectX work with newer graphic card features for example, a game using DirectX 9 has less to work with graphically than a game using DirectX 10, theoretically.

As far as I have seen, having the newer version should not be an issue however, I have never seen a game that did not come with the required DirectX version in its installer, so there really shouldn't be a problem either way. It is essential that you have the version required of by the video game, or higher. The required version should always be included as part of a game's installation process, so you often end up with multiple versions.ĭirectX is simply the software in the middle, that acts as the translator between your graphic card and the game you are playing, among other things 1. DirectX should support earlier versions, and as PTwr suggests, is often the culprit of 'missing DLL d3dx9_.dll' messages. TL DR: DirectX is a redistributed library that helps the game talk to your hardware.
