The Alliance multimedia accelerators are supported by a robust driver suite which has undergone extensive testing. Frankly, I have no idea, datasheet also mentions Z-buffer compression, but the card does not behave like if it has more memory than others. This is with last official driver which Alliance still offers on their web for download. Let me guess, they split the bit bus into two. Texturing however, is so warped it turns your accelerated games into chaos barfed all over your display. They are still alive today, albeit they moved away from semiconductors.

Alliance got more attention from gamers when their graphics cores were chosen for Voodoo Rush aliance supporting 3D only chipset of 3Dfx. Perspective correction might have been very well implemented without performance penalty, but somehow at the end all important textures are not adjusted. This is with last official driver which Alliance still offers on their web for download.
Alliance promised all-in-one solution for new multimedia age. Additional Company information can be found on our home page: And then you fire up the card, play games and everything is broken. True color textures are full speed and true color buffer is also possible with a small performance penalty.
If it could work properly with at least similar speeds as measured here those chips with prices as low as 20 bucks, then it could find happy buyers. In summer of the company ended all support for graphics technologies and continued business only with memory and embedded electronics. Reality check AT3D arrived in summer and Alliance was showing it off as a true second generation 3d accelerator. That is the fun of early 3d accelerators. Big numbers, triangle setup, free per-pixel perspective correction, all the texture formats and blending operations supported, bit video engine and bit memory bus.
Even specular highlights are done via stipple mask.
Alliance manufactures many of its products using advanced 0. Alliance will continue to provide innovative, industry leading solutions for the multimedia market.
However, at such depth only palletized textures may be blended “properly”.

This engine performs geometry setup prommotion hardware which enables the main CPU to perform more critical tasks. Frankly, I have no idea, datasheet also mentions Z-buffer compression, but the card does not behave like if it has more memory than others.
AT3D delivers true state-of-the-art 3D acceleration, including on-chip hardware geometry setup, to bring the fast frame rates of console gaming to the PC platform.
It reminds me of certain quadrilateral texturing chip trying to render triangles. Such artifacts also prevents closer inspection of Alliances Pseudo Bilinear texture filtering.
Normally such image quality would disqualify the card from benchmarks, but just to get some idea of it’s performance I measured few games that were recognizable. The last thing I can deduce from such awful gallery is per polygon mip-mapping with unstable mip selection.
Alliance Press Release
The Company designs, develops, and markets its products to the desktop and portable computing, networking, telecommunications and instrumentation markets. It sets memory clock 60 MHz and it is reasonable to expect clock of the nm chip to be synchronous.
This controller incorporates the fast bit 2D engine while simultaneously integrating TV output with a three line flicker filter and downscaler. All texture formats from palletized up to are supported. Company Information Alliance Semiconductor Corporation is a leading worldwide supplier of high performance memory and memory intensive logic products.
I am of course testing pure AT3D board. And since AT3D does not use system memory there is with 4 Aloiance little hope for true color rendering at higher resolutions. Removing the expansion memory would make the EDO work in single cycle mode rather than interleaved. The chip also supported odd sizes of 1. They are still alive today, albeit they moved away from semiconductors.
Let me guess, they split the bit bus into two. Well, that was fast.
