Internally the G is a bit processor, using what Matrox calls a “DualBus” architecture. 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. Matrox was known for their quality analog display output on prior cards and the G is no exception. This was attributed both to its architecture and to the poor drivers it relied on for much of its life especially OpenGL ICD. Unfortunately, because of the identical core clock and due to lower memory bandwidth, G was slower than G in games. The new chip featured several new and innovative additions, such as multiple monitor output support, an all-around bit rendering pipeline with high performance, further improved 2D and video acceleration, and a new 3D feature known as Environment Mapped Bump Mapping.

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 within the chip to each of its functional units.
Matrox only supports HeadCasting feature through the bundled Matrox Digimask software, which have never become popular. It is purely a Direct3D 6.
The G is a video card made by Matroxreleased in September However, the Warp engine was programmable which theoretically enhanced flexibility of the chip. The result was the best quality bit and bit color modes available at the time.
Matrox stopped support for Marvel GTV early because there was no way to make it fully functional in Windows Unfortunately, because of the identical core clock and due to lower memory bandwidth, G was slower than G in games.
It added some new features to DualHead that worked with Internet Explorer to make pages show up on g45 screens at once.

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 bit bus reduces the board’s complexity and cost because fewer traces g50 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 chip had maxxtor pixel pipelines with 3 texture units each. The situation was eerily similar to what had happened with the older G, with its near-total lack of credible OpenGL support. This is an evolution of G’s “DualBus”, which had been bit.

The G continually received official driver updates into All articles with dead external links Articles with dead external links from April Webarchive template wayback links. 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.
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 3D capabilities of G were identical to G As said earlier, G suffered at launch from driver problems.

maxtoe Hardware MJPEG capturing can be unstable but software compression, using a good video codec, gives much better results anyway. This page was last edited on 4 Januaryat This meant that the primary monitor could run much higher resolutions and refresh rates than the secondary. Despite the feature, it is inaccessible by DirectX driver.
A Matrox “DualBus” chip consists of twin unidirectional buses internally, each moving maxtkr into or out of the chip.
