This is a generic DirectX error telling you the video card driver crashed. Try updating the driver if you haven't already.
Since lowering the graphics options has helped, there is probably one setting that is giving you trouble, for example, antialiasing, lighting 2.0, etc. Try turning various settings back on until you find the one that causes the crash.
