r@gdoll_phys1csI know this thread is old, but wow. Some of you are very misinformed.
Well, 3DFX's SLI, and NVidia's SLI are a very different technology. NVidia, and ATI have implemented the SLI features on the motherboard chipset. While 3DFX implented it on the card.
3DFX's version is more compatible with a wide range of boards. However it requires a slightly complicated cable setup. You have to connect the cards on the inside, with a ribbon cable. Then you need to "jump" the video from one card to the other. Then "jump" it again, to your main video card (if it is a Voodoo2 or earlier).
Also, the 3DFX SLI had each card render a frame, alternating back and forth. NVidia SLI, and ATI Crossfire each handle this differently. I think it can be controlled by software, for newer cards. Allowing one card to render transparencies, or particle effects, or other post-rendering effects, while one renders the game. One card could calculate Shadows, or in a few years, it could calculate the Physics. In this respect, the 3DFX version is very limited.
There are more differences, but the details are technical. About the only similarities are the name (trademarked 3DFX then NVidia), and the result.
not bad, considering the age of the video card and the complexity of doom 3. Kinda reminds me of quake 3
dame VooDoo thay gave up video suprised it even ran it at all man that is so bad looking.

They converted the textures to take advantage of the glide engine inside the Voodoo. For Voodoo fans, this is the start of making a comeback for the voodoos like the Voodoo 4-5 series. The Voodoo 5 6000 was the first to break the texture speeds at all.
