Matrox Parhelia 128MB Graphics Driver

With the release of the Matrox Parhelia MB earlier this year, the company has returned to the race, offering a 3-D graphics card that distinguishes itself more by its feature set than by raw performance.

Most notable is its ability to drive three CRTs simultaneously and, for some games, Matrox Parhelia 128MB Graphics spread the 3-D graphics across the three screens to create what Matrox calls Surround Gaming. The Parhelia is an intriguing product, but its unique features can't overcome its underwhelming 3-D performance. The Parhelia delivers high-fidelity graphics with its GigaColor technology.

Conventional bit color actually consists of 24 bits of color and an 8-bit alpha channel for translucency and transparency. By reallocating the bits to give red, green, and blue 10 bits each, Matrox increases the Matrox Parhelia 128MB Graphics of colors from The downside is that only 2 bits remain for alpha blending, which in 3-D games is often insufficient.

But Matrox Parhelia 128MB Graphics applications where alpha blending isn't critical, this can be a useful feature. Matrox has also implemented filtering circuitry on the Parhelia's eight-layer circuit board to ensure cleaner signal output to display devices.

Another unique feature of the Parhelia is fragment anti-aliasing, which performs line anti-aliasing instead of applying anti-aliasing techniques to the entire 3-D scene. The card can scan a scene, detect where each object's edges are, and apply anti-aliasing to those edges Matrox Parhelia 128MB Graphics reduce or eliminate the stair-stepping jaggies often seen in 3-D games. By working only on object edges, which make up just 5 to 10 percent of the on-screen pixels, the Parhelia can apply up to 16X anti-aliasing.

This approach works well, but it isn't compatible with all games. For instance, the new flight simulator IL-2 Sturmovik does not work correctly using fragment anti-aliasing.

However, ATI's Radeon was released later that year, with a considerably larger transistor count million vs. The card's fillrate performance was formidable in games that used many texture layers; though equipped with just 4 pixel pipelines, each had 4 texture units.

This, unfortunately, proved not to be an efficient Matrox Parhelia 128MB Graphics in most situations. While the Parhelia possessed an impressive raw memory bandwidth much of it was wasted on invisible house-keeping tasks because the card lacked the ability to predict overdraw or compress z-buffer data, among other inefficiencies. Some writers believed Parhelia to have a "crippled" triangle-setup engine that starved the rest of the chip in typical 3D rendering tasks [1].

Matrox Parhelia 128MB Graphics Later in Parhelia's life, when DirectX 9 applications were becoming quite prevalent, Matrox acknowledged that the vertex shaders were not Shader Model 2. Presumably there were several bugs within the Parhelia core that could not be worked around in the drivers.

However, it was all a bit of a moot point because Parhelia's performance was not adequate to drive most DirectX 9-supporting titles well even without more complex shader code Matrox Parhelia 128MB Graphics the card down. Sales[ edit ] Despite the lackluster performance for its price, Matrox hoped to win over enthusiasts with the Parhelia's unique and high quality features, such as "Surround Gaming", glyph acceleration, high resolutions, and 16x fragment anti-aliasing.

However, within a few months after release, the Parhelia was completely overshadowed by ATI 's far faster and fully DirectX 9. Due to their equivalent pricing against faster cards, the Parhelia never got a significant hold in the Matrox Parhelia 128MB Graphics.

It remained a niche product, while nVidia and ATI control the majority of the discrete graphics chip market.
