San Jose, California - November 13, 2000 - 3dfx Interactive® Inc. (NASDAQ:TDFX) announced today that it has licensed its 4-way Scanline Interleave (SLI™) technology, based on the Voodoo5™ 6000 AGP project, to Quantum3D to be incorporated into their AAlchemy™ family of PC-based systems for visual simulation and training applications. The company also announced that its 4-way SLI technology, which has achieved 43 percent better Quake 3 graphics performance over leading competitive solutions, will be available exclusively from Quantum3D, and will not be available in the retail channel.

3dfx will demonstrate its exceptional 4-way graphics performance at the Comdex/Fall trade show, November 13 - 17, 2000 in Las Vegas, NV, to a select group of customers, media and industry analysts. The demonstrations will show the 4-way design's ability to display high resolution images, with superior full-scene anti-aliasing (FSAA) enabled. The 4-way SLI design is the first graphics card able to achieve greater than 60 fps (frames per second) performance in Quake 3 benchmarks at the ultimate screen resolution of 1600x1200x32-bit color.

"The raw power, ground-breaking technology and superior performance of the 4-way SLI design proved to be another perfect match for Quantum3D's visual simulation and training marketplace," said Ross Q. Smith, founder and vice president of sales and marketing at Quantum3D. "For the first time ever, visual simulation and training integrators can choose from a software compatible product family that delivers the precise amount of high fidelity performance that their applications require and their budgets can accommodate."

3dfx has a long history of leveraging its leading-edge 3D technology into the visual simulation environment with Quantum3D. Starting with 3dfx's revolutionary and award-winning Voodoo2™ and Voodoo3™ products and now with its scalable VSA-100 accelerators, Quantum3D has successfully migrated 3dfx technology into today's most demanding 3D graphics arena.

"Licensing our breakthrough 4-way SLI technology to Quantum3D is the best way to expend our engineering resources in a way that offers the best return," said Byran Longmire, vice president of the graphics business unit. "While we are sympathetic to the disappointment this may cause to a small number of our loyal gaming consumers, we're looking forward to seeing this incredible technology marketed to the visual simulation industry where visual quality is the most important attribute."
