Unfortunately, because of the identical core clock and due to lower memory bandwidth, G was slower than G in games. Only a few games supported the feature, such as Dungeon Keeper 2 and Millennium Soldier: This is an evolution of G’s “DualBus”, which had been bit. Despite the feature, it is inaccessible by DirectX driver. This increases the efficiency and bandwidth of data flow within the chip to each of its functional units. Video capturing was possible but drivers are still based on VfW. G was known for being particularly dependent on the host system’s CPU for high 3D performance.

In other projects Wikimedia Commons. The result was the best quality bit and bit color modes available at the time.

It was also equipped with a hardware transform and lighting unit capable of processing 20—30 million triangles per second. Even with initial driver difficulties, Matrox G was very competitive. This increases the efficiency and bandwidth of data flow within the chip to each of its functional units.

A Matrox user going by name Adis hacked original drivers to make the card work under Windows The DualHead capability not only offered desktop widening but also desktop cloning two screens showing the same thing and a special “DVDMAX” mode which outputs video overlays onto the second monitor. Matroxx are no WDM drivers available for this card.

The G continually received official driver updates into 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. 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. G’s rendering pipelined uses what Matrox called “Vibrant Color Quality 2” VCQ2a functionality in which all internal 3D calculations are done with bit precision.


As said earlier, G suffered at launch from driver problems. OnMatrox Graphics Inc.


Hardware MJPEG capturing can be unstable but software compression, using a good video codec, gives much better results anyway. Retrieved from ” https: However, contrary to the video mode’s name, G does not support full DVD decoding hardware acceleration. Matrox only supports HeadCasting feature through the e866 Matrox Digimask software, which have never become popular. It does this by improving on the 96 constant registers specified for by DirectX 8. This feature is known as “DualHead” and was ett866 decisive edge for Matrox over the card’s competitors at the time.

This driver was a precursor to a fully functional OpenGL ICD driver, a quick development to improve performance as fast as possible by offering an interim solution. This was the same as G From Wikipedia, the free encyclopedia. MGA-G processor added a second pixel pipeline, hardware transform and lighting, and natrox HeadCasting Engine, a hardware implementation of a vertex shader for accelerated matrix palette skinning.

Matrox made it very clear that they were natrox to supporting OpenGL, however, and development rapidly progressed. Matrox tried to make stable drivers for several months but with no luck.

Only a few games supported the feature, such as Dungeon Keeper 2 and Millennium Soldier: The goal was to prevent dithering and other artifacts caused by inadequate precision when performing calculations.

Matrox was known for their quality analog display output jatrox prior cards and the G is no exception.

Unfortunately Matrox never described the functionality of this component in-depth so little is known about it.

G does have partial support for the DVD video decoding process but it does not perform inverse discrete cosine transform IDCT or motion compensation in hardware the two most demanding steps of the 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.
