i have a gainward ultra 750xp ti4600 golden sample card that i just bought. the problem is, when i install the card with the drivers and software (expertool) that came with the card, it will not run 3D mark 2001, i get a message saying my card is not directx 8.1 compatible. in expertool it shows that directx is not installed and that i have windows xp home. but if i got to "information" it shows directx 8.1 and windows xp pro (which is correct)???? i have tried uninstalling the drivers and installing the new ones from invidias site and still have the problem........ the only way i got the card to run 3D mark 2001 was to install it with the drivers from my old Elsa Gladiac 920 card, it installed as a Gladiac 925 and reported the correct amount of memory (128mb)??? i'm sorry if this is kind of confusing, i know it is to me!!!.... can i have some problem with something left on my system from my elsa card? anyone else have this problem or a solution?? thank you for any help, this is driving me nuts...
