This driver is from omega drive...its for Voodoo 5... its the best I have found. Im a diehard gamer (ultima online, everquest, etc) and this card has never crashed, and its wayyyyy better than the original drivers from 3dfx... i mean the detail is hella better....definately noticeable. I run it & recommend it... its not an self-install so hopefully you know how to configure it through device manager ) Its for windows 9x and me os's.
