I received call of duty 4 for xmas and am unable to play it. I have been reading numerous posts on how to be able to play it and have tried some things also. I did install 3D analyze (to max out pixels, etc) and when I tried to play the game I received the error : Video card or driver doesn't support UBYTE4N vertex data Here is the information on my video card: Intel 82915G/GV/910GL Express Chipset Family I also know I have a PCI slot for another video card. If I do need to buy a new video card where do I go to get one at a reasonable price? If not what do I need to do to play the game? Thank you for any and all help!!
