MATROX PARHELIA PCI DRIVER

Dual link TMDS is supported via external controller connected to the digital interface. However, only 2 displays can be controlled independently. 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 weighing the card down. The Parhelia processor featured Glyph acceleration, where anti-aliasing of text was accelerated by the hardware. The “Surround Gaming” support allowed the card to drive three monitors creating a unique level gaming immersion.

Released init was best known for its ability to drive three matox “Surround Gaming” and its Coral Reef tech demo. Due to their equivalent pricing against faster cards, the Parhelia never got a significant hold in the market.

While oarhelia 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. 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 weighing the card down. The “Surround Gaming” support allowed the pahrelia to drive three monitors creating a unique level gaming immersion.

In this case it was the ATI Radeonreleased only a few months later.

To further improve analog image quality, 5th order low-pass filters are used. Some writers believed Parhelia to have a “crippled” triangle-setup engine that starved the rest of the chip in typical 3D rendering tasks [1]. As had happened with previous Matrox products, the Parhelia was released just before competing companies released cards that completely outperformed it.
