This increases the efficiency and bandwidth of data flow within the chip to each of its functional units. Despite the feature, it is inaccessible by DirectX driver. Perhaps the most notable feature of G is its ability to drive two separate monitors to display a single desktop. Findings within a release of Matrox graphics drivers MGA Overclocking tests showed that the core was unable to achieve higher speeds than G even though it was manufactured on a newer process. 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.

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. The chip had 3 pixel pipelines with 3 texture units each.

It added some new features to DualHead that worked with Internet Explorer to make pages show up on both screens at once. This meant that the primary monitor could run much higher resolutions and refresh rates than the secondary. 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. It was also equipped with a hardware transform and lighting unit capable of processing 20—30 million triangles per second.
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.
This feature is known as “DualHead” and was a decisive edge for Matrox over the card’s competitors at the time. A Matrox user going by name Adis hacked original drivers to make the card work under Windows However, the Warp engine was millenjium which theoretically enhanced flexibility of the chip.
EMBM requires either specialized hardware within the chip for its calculations or a more flexible and programmable graphics pipeline, such as later DirectX 8. Views Read Edit View history. Unfortunately, because of the identical core clock and due maxhor lower memory bandwidth, G was slower than G in games.

Millehnium situation was eerily similar to what had happened with the older G, with its near-total lack of credible OpenGL support. Overclocking tests showed that the core was unable to achieve higher speeds than G even though it was manufactured on a newer process.

Even with initial driver difficulties, Matrox G was very competitive. This was the same as G Matrox stopped support for Marvel GTV early because there was no way to make it fully functional in 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. Matrox tried to make stable drivers for several months but with no luck. The 3D capabilities of G were identical to G The G is a video card made by Matroxreleased in September The result was the best quality bit and bit color modes available at the time.
Retrieved from ” https: Matrox took the technology developed from the G project, refined it, and basically doubled it up to form the G processor. 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. Bthat are fully 4X compliant and run at the higher speed if the motherboard is capable as well. Hardware MJPEG capturing can be unstable but millennim compression, using a good video codec, gives much better results anyway.
Unfortunately Matrox never described the functionality of this component in-depth so little is known about it. This is an evolution of G’s “DualBus”, which had been bit. 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.
As said earlier, G suffered at launch from driver problems.
