Hello.
Could you explain to me what Direct X is, and why it can cause problems with some games / graphics cards. Thank-you.

Here's an FAQ for DirectX 9, which might be of interest:  Click Me! (http://www.microsoft.com/windows/directx/default.aspx?url=/windows/directx/productinfo/faq/default.htm)

I have heard it said that it can cause problems if you install a version of DirectX, above the specifications of your Graphics Card, but hopefully one of our techies will confirm or correct this.

Basically, DIRECTX is an instruction set, sort of like drivers, to allow your graphics cards (drivers) interact THROUGH Windows to talk to the game.

The game may call certain procedures (code) that depend on DIRECTX. Just like any other software,  DX 9 will act differently from DX 8 etc.

It gets a bit more in depth. For example, DX will work as a network gaming component,  allowing correct transfer of data between systems. Sound is also covered.
