This is an evolution of G’s “DualBus”, which had been bit. Matrox stopped support for Marvel GTV early because there was no way to make it fully functional in Windows Matrox made it very clear that they were committed to supporting OpenGL, however, and development rapidly progressed. By shrinking the core, costs are reduced because more chips are made per wafer at the factory, and Matrox can take the time to fix earlier mistakes in the core, and trim or add new functionality. G’s rendering pipelined uses what Matrox called “Vibrant Color Quality 2” VCQ2 , a functionality in which all internal 3D calculations are done with bit precision. The result was the best quality bit and bit color modes available at the time.

Matrox Millennium G450 DualHead graphics card – MGA G450 – 16 MB Series

Views Read Edit View history. Codenamed ” Toucan “, it was a more powerful and refined version of its predecessor, the G The chip had 3 pixel pipelines with 3 texture units each. G dialhead known for being particularly dependent on the host system’s CPU for high 3D performance.

The transition to true 3D accelerators Rendition Verite, Voodoo, Voodoo2, TNT, etc… caught Matrox off guard and before they could react, the best feature they could claim was that their 2D looked good.

Matrox took the technology developed from the G project, refined it, and basically doubled it up to form the G processor. Matrox only supports HeadCasting feature through the bundled Matrox Digimask software, which have never become popular. It is purely a Direct3D 6. Overclocking tests showed that the core was unable to achieve higher speeds than G even though it was manufactured on a newer process.


Where many cards were crippled by blurry output, especially as the resolution and refresh rate increased, the Matrox cards delivered very sharp and clear images.

The result was the best quality bit and bit color modes available at the time. Boards shipped with dual analog VGA connectors. Matrox was known for their quality analog display output on prior cards and millennum G is no exception.

A Matrox “DualBus” chip consists of twin unidirectional buses internally, each moving data into or out of the chip. With that, we never heard another peep out of Matrox.

Matrox Millennium G

In spite of this, the G did boast very impressive image quality, both in 2D and 3D rendering situations. MGA-G processor added a second pixel pipeline, hardware transform and lighting, and the HeadCasting Engine, a hardware implementation of a vertex shader for accelerated matrix palette skinning. However, contrary to the video mode’s name, G does not support full DVD decoding hardware acceleration.

With regard to its hardware, Duaphead triangle setup engine, called the “Warp Engine” ironically, was somewhat slower than the counterparts aboard the competition’s cards. This increases the efficiency and bandwidth of data flow within the chip to each of its functional units.

The goal was to prevent mattox and other artifacts caused by inadequate precision when performing calculations.

This was the same as G However with only one flagship product, 3dfx is definitely in need of a lower cost VSA part Voodoo4 where are you? Companies that we once anticipated graphics chipsets from have been more than just quiet over the past year.

Despite the feature, it is inaccessible by DirectX driver. However, the Warp engine was programmable which theoretically enhanced millnenium of the chip. Hardware MJPEG capturing can be unstable but software compression, using a good video codec, gives much better results anyway.

Due to this lack of industry-wide support, and its toll on the limited graphics hardware of the time, EMBM only saw limited use during G’s time. A Matrox user going by mtrox Adis hacked original drivers to make the card work under Windows This was attributed both to its architecture and to the poor drivers it relied on for much of its life especially OpenGL ICD.

The situation was dualheqd similar to what had happened with the older G, with its near-total lack of credible OpenGL support. Only a few games supported the feature, such as Dungeon Keeper 2 and Millennium Soldier: The G is a video card made by Matroxreleased in September
