The result was the best quality bit and bit color modes available at the time. This meant that the primary monitor could run much higher resolutions and refresh rates than the secondary. This page was last edited on 4 January , at Overclocking tests showed that the core was unable to achieve higher speeds than G even though it was manufactured on a newer process. Eventually a native OpenGL driver called “TurboGL” was released, but it was only designed to support several popular games of the time e. G was known for being particularly dependent on the host system’s CPU for high 3D performance. Retrieved from ” https:

As said earlier, G suffered at launch from driver problems. Retrieved from ” https: The situation was eerily similar to what had happened with the older G, with its near-total lack of credible OpenGL support. Bthat are fully 4X compliant and run at the higher speed if the motherboard is capable as well.
This meant that the primary monitor could run much higher resolutions and refresh rates than the secondary. EMBM requires either specialized hardware within the chip for its calculations or a more flexible and programmable graphics pipeline, such as later Sual 8.

A bit bus reduces the board’s complexity and cost because fewer traces have to be used, and potentially the pin-count of the graphics processor can be significantly reduced if the chip is designed only for a bit bus. The 3D capabilities of G were identical to Matroxx Perhaps the most notable feature of G is its ability to drive two separate monitors to display a single desktop.
There are no WDM drivers available for this card. The G is a video card made by Matroxreleased in September Matrox’s award-winning Powerdesk display drivers and control panel integrated Dualhead in a very flexible and functional way that become world-renowned for its effectiveness.
Where many cards were crippled by blurry output, especially as the resolution and xpp rate increased, the Matrox cards delivered very sharp and clear images. This feature is known as “DualHead” and was a decisive edge for Matrox over the card’s competitors at the time.
Hardware MJPEG capturing can be unstable but software compression, using a good video codec, gives mafrox better results anyway.
However, the Warp engine was programmable which theoretically enhanced flexibility of the chip. Matrox made it very clear that they were committed to supporting OpenGL, however, and development rapidly progressed.
Video capturing was possible but drivers are still based on VfW.
Unfortunately Matrox never described the functionality of this component in-depth so little is known about it. 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 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.
This increases the efficiency and bandwidth of data flow matrx the chip to each of its functional units. The goal was to prevent dithering and other artifacts caused by inadequate precision when performing calculations.
A Matrox “DualBus” chip consists of twin unidirectional buses internally, each moving data into or out of the chip. It was also equipped with a hardware transform and lighting unit capable of processing 20—30 million triangles per second.

The G continually received official driver updates dp This page was last edited on 4 Januaryat 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.
Despite the feature, it is inaccessible by DirectX driver. With regard to its hardware, G’s triangle setup engine, called the “Warp Engine” ironically, was somewhat slower than the counterparts aboard the competition’s cards.
Unfortunately, because of the identical core clock and due to lower memory bandwidth, G was slower than G in games. This is an evolution of G’s “DualBus”, which had been bit. All articles with dead external links Articles with dead external links from April Webarchive template wayback links.
