Your card is probably a VooDoo 2 or someting like that. My friend have the same problem and i think there is no way to bypass it. Anyway, if u find someting, let me know ...
There is NO way to by pass this my friend, your videocard doesn't have "multitextering", my videocard said that when I tried to play, I just spent around $80 and bought a Nvidia TNT2 32mb card that runs the game.
