3DLabs Generic PerMedia2 3D Accelerator Driver

Permedia 2 3Dlabs can be proud to be among first gaming texture mapping 3d accelerator to the PC. However Gaming Glint was not very useful and did not gain the company any valuable mindshare. Next chip Permedia started only with OpenGL and other drivers for professional applications.

Still their owners were among the lucky few of the time who could enjoy accelerated GlQuake. When second generation Permedia arrived to the market in the fall of with support for both Direct3D and OpenGL, gamers were watching.

It was quite an advanced chip with significantly higher per clock performance than first Permedia. It kept high quality, high resolution output qualities of professional boards, and seemed further proof for the time.

The card Nothing much to get excited about, Permedia 2 boards look simple, cost efficient. Creative Labs surprisingly avoided first Permedia, but they came back to 3Dlabs for the second.

Either my card is unlucky or Creative pushed this one to the max. From CT's 83 MHz you cannot gain more than two megahertz without running into artifacts. That's why there aren't overclocking results.

Under the heatsink you would find Texas Instruments logo as 3DLabs Generic PerMedia2 3D Accelerator and the chip is also known under their codename as TVP The alliance continued, Permedia 2 integrates TI's MHz DAC technology with x32 bit texture lookup table supporting four and eight bit paletted textures. Last generic Permedia 2 driver version from April is used. Even professional FireGL card doesn't look dangerous.

3Dlabs Permedia 2 review

Clocks are a bit relaxed at 80 MHz. Pipeline queue, sideband addressing and direct texturing from system memory are supported.

Triangle setup engine claims MFLOPS just like Delta, but unless it has separate clock domain it had to be redesigned for halved per clock performance. Graphics pipeline itself is a mere evolution of first Permedia, again using 3d units as superset of 2d functions. Host accessible is also output FIFO 32 bits wide.

Smooth vertex shading in 16 bit color depth requires manually enabled "free" dithering. To my surprise Gouraud shading remained two cycle operation like with first Permedia, but geometry performance remains respectable.

Subpixel precision can be selectively adjusted per polygon or even disabled to speed up rendering. Texture address unit also properly handles perspective correction, however there is an option for less accurate division to avoid speed impact.

In any case the correction is faster and more precise than with first Permedia. Addresses are then passed to texture read unit for fetching needed texels. Texturing unit is backed by cache sufficiently speeding up bilinear and even trilinear filtering, but mip mapping can still be more costly. 3DLabs Generic PerMedia2 3D Accelerator texture formats of 15 and 16 bit RGB A are supported, true color textures were for some reason disabled.

Additional LUT formats are available for 2d rendering as well. Fog unit applies linear interpolation per vertex with value calculated by host function and can reject completely fogged fragments from plotting. Blending unit supports various logical functions, 3DLabs Generic PerMedia2 3D Accelerator additive texture blending needed in many advanced games is still unavailable. Newly implemented optimization can skip frame buffer reads of pixels covered by texel with alpha value of one.

In the end dithering can adjust colors into final format and I did not always like what this stage does. Memory controller looks the same, but buffers in local memory now do not have to be allocated continously.
