Im not even sure if there is a “gaming” driver so to speak. I just need one that would make tweaks for the changes made to the latest games. I went to the 3dfx.com site but can’t tell the wheat from the chafe. Im specifically having trouble with having the new games allow my external gamma settings to have an effect.
The latest driver for the Voodoo is about 1 year old when 3dfx folded. (There may be newer hack floating around but I doubt it)
Look for Beta Voodoo drivers or the such, I am using these on my Voodoo 3500 and in most games I can do gamma tweaks, that is if my card works at all.
Sorry I can’t help more, but I will look at what drivers I have at home and I can PM and tell you if you can use them.
