I've got pretty much the exact recommended system on the bottom of the Rogue Spear box: G3 300 (beige), 160 MB RAM, Voodoo5 card. But the 3-D rendering is awful. Slow, jerky, low detail. It can't be even using the Voodoo card. Must be using software rendering. But there aren't any options in the game for manually setting the video card, at least none that I can find. The Voodoo card works fine; Unreal Tournament, Quake 3 and Myth II all are smooth as silk with beautiful lighting effects. It's like the game didn't autodetect the card on install. If anyone has any ideas, I'd be grateful. I'm using 3dfx drivers 1.1.2. I hear there's a 1.1.3b version out there, but I can't find it. I'm also using Apple's OpenGL 1.2.1 drivers.
If there's no fix for this, I'm gonna have to return this, 'cause it's terrible.
