The newer Millennium card also contained 3D capabilities similar to the Impression Plus, and was nearly as limited. Without support for texturing, the cards were very limited in visual enhancement capability. Millennium received slightly more game support, but primarily only in bundled titles such as NASCAR Racing

 that only received slight performance improvements with little quality gain. The answer to these limitations, and Matrox's first attempt at targeting the consumer gaming PC market, would be the Matrox Mystique. Based heavily on the Millennium but with various additions and some cost-cutting measures, Mystique would offer gamers more of what they wanted for new 3D game titles.

 processes and 3D hardware architecture design expertise was limited. Including bilinear filtering would have incurred a significant cost in the chip's transistor budget for more computational resources and potentially reduce graphics core clock speed and performance due to a larger chip design. There was also the manufacturing cost consideration that comes with a larger processor size. Matrox's words were not without weight because the Mystique did handily outperform the other 2D/3D boards at the time, such as S3 ViRGE and early ATI Rage

 products, although its visual quality was lower than those accelerators.

In general, compared to its peers, the Matrox Mystique was a competent board with its own set of advantages and disadvantages as was typical in this era of early 3D accelerators. It performed well for an early 2D/3D combo card, but it had questionable 3D visual quality. Its 2D support rivaled the best cards available for performance and quality, however. It was not uncommon to pair up the Mystique or another Matrox card with a 3Dfx Voodoo Graphics 3D-only board because the Voodoo cards were the fastest and most well-supported 3D accelerators at the time. Detractors, however, referred to the card as the "Matrox Mystake".

Driver support for the Mystique was robust at launch. The card directly supported all of Microsoft's operating systems including MS-DOS, Windows 3.1x

Mystique 220

Matrox released a newer version of the Mystique in 1997. The name gives the only significant change, that being the RAMDAC running at 220 MHz . This made the Mystique equivalent to the original Millennium for high-resolution 2D resolution support. The chip on the board was called MGA1164SG instead of MGA1064SG (original Mystique) as well. Otherwise, the card was identical in feature-set to the original Mystique and offered almost identical performance.

A special business-oriented version of Mystique 220, called Mystique 220 Business, was launched as well. This card came with a different software bundle targeting business users and excluding the games. The actual hardware was identical.

Legacy

The memory and internal RAMDAC programming interface lived on in MGA-G100 and later processors, until the introduction of Matrox Parhelia
