3DLABS PERMEDIA DRIVER

Reviews were keen on Permedia 2 for being almost first professional product that can play games as well, even if not so fast. While it should have allowed single cycle 3d pixel performance I could not get significantly above results of two cycle-like speed no matter how many features were disabled, Gouraud shading included.

I will use lightmap from Quake, but mind you this was observed in any application.

Permedia 2 3Dlabs can be proud to be among first gaming texture mapping 3d accelerator to the PC. Lands of Lore 2 looks correct as well, but performance dived below 2 fps. That’s why there aren’t overclocking results. Permedia supports RGBA textures, but their use is extremely limited due to poor memory management. All can be covered under DMA engine and there is also option of direct memory access around the pipeline. Creative Labs surprisingly avoided first Permedia, but they came back to 3Dlabs for the second.

The rest of the permefia remain fairly stationary in terms of the standings, however the Savage4 exhibits very Matrox like behavior in this benchmark as it dropped from a render time of seconds down toa drop of 97 seconds. Four texture formats of 15 and 16 bit RGB A are supported, true color textures were for some reason 3dpabs.

Local memory was unified to maximize capacity utilization and all the traffic now goes through casual 64 bit bus, yet 32 bit framebuffer does not significantly slow down rendering. Looking at the Malta print on the chip one can guess the manufacturer is ST Micro.

These tests will be remembered as endless fight for more texture memory. Texels warps by camera angel and form clear abnormalities like the vertical line in the center. Permedia 2 not only offers various masks like scissor, chroma and 3d,abs component tests, but whole pipeline can be skipped and host can use direct access to local buffer for custom programs.

To get reasonable compatibility disable rectangular allocator and enable texture compression for OpenGL.

While it should have 3dpabs single cycle 3d pixel performance I could not get significantly above results of two cycle-like speed no matter how many features were disabled, Gouraud shading included. Textures are finally seen in Unreal, though lightmaps cannot be blended with it.

Archived from the original on February 8, Subsidiary of Creative Technology. Quake 2 or nothing. The Permedia 3 comes away once again, with a smooth first place holding.

Creative 3D Blaster VLB failed to impress, but even before its release 3Dlabs was already making waves about much improved consumer chip for Architecture The pipeline is controlled by 32 bit registry file preceded by 64 entry deep 41 bits wide FIFO, to accommodate with data also 9 bit tag.

But without it, the Permedia will just drop almost all textures in GlQuake. Clocks are a bit relaxed at 80 MHz.

When results from driver came together, comparison against similar kind of products like Revolution 3D and Millennium 2 seem to be good idea, but Permedia is lagging behind even more.

Many projectiles in shooting games depend on texture multiplication to make their edges transparent, Permedia has to render the transparent pixels black.

Older games suits it well and impact from optional true color rendering is rather small. Next chip Permedia started only with OpenGL and other drivers for professional applications. Archived from the original on December 18, Delta also increased floating point and sub pixel precision.

Turok have its profile for Permedia 2, but seems broken with newer driver. How about slowest version of Matrox Mystique? When their market share shrunk beyond recovery time has come for controlled bankruptcy in
