Don't have much to say here, but NKF mentioned something I thought should be archived anyway:
I have a voodoo2 and it purrs along happily for all three of the primary games. The actual problem with the card (and for that matter, a whole bucketload of other computer peripherals and hardware) may stem from certain computer configurations and or the device drivers. They can really make or break a game. Sad, but true. Blame the OS manufacturer! Rah! Rah!
