Hi:
G4xx card play CS by D3D is OK,I use 1024x768 is very smooth(no delay),byt when U play CS by OpenGL will easy to 當機 ,because G4xx is very weak of OpenGL!When U visit Matrox offical game forum,U can see many many ppl have same problem of CS!

CS +Via chipset +OpenGL =整個死當

Last month I change ATI LE ,today use OGL play CS very happy!
