So the Voodoo is an amazing card for older PCs, but what about the Mac? Is it even possible to run a PCI 3D graphics card made for Windows under Mac OS? This is just a quick overview and a test of a 3Dfx Voodoo2 PC card being installed in a Mac Performa 6400 computer, using special Glide extensions. Quake is used for benchmark purposes, because it's awesome. Yes, there were Macintosh versions of the Voodoo cards made, but those are somewhat hard to come by. But this is the testing of a card without the Mac BIOS, originally made for PCs!
