Does anyone know how to get this card to work with games? Because in the compatibility list games like Diablo and Warcraft work on NT4 but on my system it doesn't. Are there any drivers or setups that can get this thing to work? The only game that I could run so far would be Quake III. I'm running a Win NT4 SP6 on an HP Kayak XU 7/550 550Mhz Intel Pentium III Xeon. Any help would be appreciated.
