MATROX Marvel G450 eTV Driver

Matrox took the technology developed from the G project, refined it, and basically doubled it up to form the G processor.

TV Tuner Video Card Roundup

The new chip featured MATROX Marvel G450 eTV 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. Internally the G is a bit processor, using what Matrox calls a "DualBus" architecture.

This is an evolution of G's "DualBus", which had been bit.

A Matrox "DualBus" chip consists of twin unidirectional buses internally, each moving data into or out of the chip. This increases the efficiency and bandwidth of data flow within the chip to each of its functional units. G's 3D engine consists of 2 parallel pixel pipelines MATROX Marvel G450 eTV 1 texture unit each, providing single-pass dual-texturing capability.

It is purely a Direct3D 6. Perhaps the most notable feature of G is its ability to drive two separate monitors to display MATROX Marvel G450 eTV single desktop. This MATROX Marvel G450 eTV is known as "DualHead" and was a decisive edge for Matrox over the card's competitors at the time. 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'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. However, contrary to the video mode's name, G does not support full DVD decoding hardware acceleration.


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. Due to this lack of industry-wide support, and its toll on the limited graphics hardware of the time, EMBM MATROX Marvel G450 eTV saw limited use during G's time. Only a few games supported the feature, such as Dungeon Keeper 2 and Millennium Soldier: EMBM requires either specialized hardware within the chip for its calculations or MATROX Marvel G450 eTV more flexible and programmable graphics pipeline, such as later DirectX 8.

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. The goal was to prevent dithering and MATROX Marvel G450 eTV artifacts caused by inadequate precision when performing calculations.

The result was the best quality bit and bit color modes available at the time. Matrox was known for their quality analog display MATROX Marvel G450 eTV on prior cards and the G is no exception.

Backoffice Europe

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. Bthat are fully 4X compliant and run at the higher speed if the motherboard is capable as well.

Performance[ edit ] G was known for being particularly dependent on the host system's CPU for high 3D performance. This was attributed both to its architecture and to the poor drivers it relied on for much of its life especially OpenGL ICD.

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. However, the Warp MATROX Marvel G450 eTV was programmable which theoretically enhanced flexibility of the chip. Unfortunately Matrox never described the functionality of this component in-depth so little is known about it.

As said earlier, G suffered at launch from driver problems. The MATROX Marvel G450 eTV was eerily similar to what had happened with the older G, with its near-total lack of credible OpenGL support. Matrox made it very clear that they were committed to supporting OpenGL, however, and development rapidly progressed.


Eventually a native OpenGL driver called "TurboGL" was released, but it was only designed to support several popular games of the time e. 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 MATROX Marvel G450 eTV.

The G continually received official driver updates into Even with initial driver difficulties, Matrox G was very competitive. Matrox tried MATROX Marvel G450 eTV make stable drivers for several months but with no luck. A Matrox user going by name Adis hacked original drivers to make the card work under Windows Video capturing was possible but drivers are still based on MATROX Marvel G450 eTV. Hardware MJPEG capturing can be unstable but software compression, using a good video codec, gives much better results anyway.

There are no WDM drivers available for this card.

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 MATROX Marvel G450 eTV. Overclocking tests showed that the core was unable to achieve higher speeds than G even though it was manufactured on a newer process. This meant that the primary monitor could run much higher resolutions MATROX Marvel G450 eTV refresh rates than the secondary.

This was the same as G
