Its promise of single cycle bump-mapping was not fulfilled. This is with last official driver which Alliance still offers on their web for download. I take abandonment of those chips as another proof of how broken the design was. Perspective correction might have been very well implemented without performance penalty, but somehow at the end all important textures are not adjusted. Bios update for Alliance Semiconductor Promotion Let me guess, they split the bit bus into two. That is the fun of early 3d accelerators.

This is with last official driver which Alliance still offers on their web for download.
And then you fire up the card, play games and everything is broken. Bios update for Alliance Semiconductor Promotion 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 chip also supported odd sizes of 1. Texturing however, is so warped it turns your accelerated games into chaos barfed all over your display. Supports SCO version 5.
Requires newbios,exe These are reference driversif possible get the drivers from you OEM vendor, if you are unsure who made you card, you can look them up using the FCC Search. Results Performance is not the worst, but it is not impressive either.

They sure feel better than MX, but I am not benchmarking 2D. I am of course testing pure AT3D board. Gouraud shading is done full speed and geometry looks perspectively ok.
No Voodoo Rush support.
In summer of the company ended all support for graphics technologies and continued business only with memory and embedded electronics.
The following files are removed from the Hard Drive and are required for Voodoo Rush support: Alliance promised all-in-one solution for new multimedia age. Logo of Alliance is on many memory chips of the nineties. And since AT3D does not use system memory there is with 4 MB little hope for true color rendering at higher resolutions. Many people often say something in early 3D chip is broken, promotoin the likes of TridentRage or even Riva Modern art lovers should enjoy the impressive gallery.
Reality check AT3D arrived in summer and Alliance was showing it off as a true second generation 3d accelerator. Removing the expansion memory would make the EDO work in single cycle mode rather than interleaved.

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. Perspective correction might have been very well implemented without performance penalty, but somehow at the end all important textures are alliancce adjusted.
Any 3d rendering scenario should be performed promootion one pass. These are reference driversif possible get the drivers from you OEM vendor, if you are unsure who made you card, you can look them up using the FCC Search.
Even specular highlights are done via stipple mask. Its promise of single cycle bump-mapping was not aliance. Win 95 driver nt 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. Could it mean AT3D is tiling the scene?
It is not only the monochrome dynamic lighting or stipple patterns used for all but one transparency mode. They are still alive today, albeit they moved away from semiconductors.

Filename Size Readme O. Technical specs says that Alliance chips got a special 64 bit bus for fast communication with Rush. Alliance Semiconductor Promotion Windows 95 driver version 4.
Conclusion Well, that was fast.
