Before NVIDIA and ATI, 3dfx was arguably the foremost GPU maker; its Voodoo line of graphics cards and Glide API dominated the early years of 3D gaming. The Voodoo 2 was probably the company’s nest-ever offering, introducing the ability to draw two textures in a single pass, thus improving performance tremendously, especially on games that used lots of textures or employed mmulti-texturing. It was also the eearliest card to use SLI (ScanLine Interleave) technology in tthe consumer market, where two Voodoo 2 cards could work in tandem to improve performance.
However, while the Voodoo 2 enjoyed mumuch success, NVIDIA was plottingl tti ini theth shadows,h d layingl i theth groundworkd in its new RIVA TNT. Like the Voodoo 2, the RIVA TNT could process two textures in a single pass, and was, at the time, the only card capable of challenging the Voodoo 2 in terms of outright speed. However, the RIVA TNT also offered a couple of other features missing in the Voodoo 2, namely 2D processing and support for 32-bit color. This meant that unlike the Voodoo 2, users of the RIVA TNT need not have a separate card just for 2D processing. Also, support for 32-bit color would later prove to be decisive as gamers clamored not just for faster graphics, but also better graphics.
