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. Well, that was fast. It sets memory clock 60 MHz and it is reasonable to expect clock of the nm chip to be synchronous. Removing the expansion memory would make the EDO work in single cycle mode rather than interleaved. This engine performs geometry setup in hardware which enables the main CPU to perform more critical tasks. And then you fire up the card, play games and everything is broken.

Alliance wt3d all-in-one solution for new multimedia age. Except for historical information contained herein, the above constitutes forward looking statements; actual results could differ materially from those projected in the forward looking statements as a result of the factors set forth in the Company’s most recent Annual Report on Form K and Quarterly Report on Form Q, respectively, each of which is filed with the Securities and Exchange Commission and available through the Company’s home page: Technical specs says that Alliance chips got a special 64 bit bus for fast communication with Rush.

And then you fire up the card, play games and everything is broken. It reminds me of certain quadrilateral texturing chip trying to render triangles.

All texture peomotion from palletized up to are supported. True color textures are full speed and true color buffer is also possible with a small performance penalty. Alliance had more plans with this architecture.


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.

Additional Company information can be found a3td our home page: But only after you see AT3D in action, you will know how much broken can things be. Reality check AT3D arrived in summer and Alliance was showing it off as a true second generation 3d accelerator. Any 3d rendering scenario should be performed in one pass. The architecture is optimized to provide fast frame rates to ensure maximum interactivity.

Removing the expansion memory would make the EDO work in single cycle mode rather than interleaved. Results Performance is not the worst, but it is not impressive either.

Even if the basics of textured polygons worked properly the AT3D would not get high image quality marks. Modern art lovers should enjoy the impressive gallery.

However, promition such depth only palletized textures may be blended “properly”. The last thing I can deduce from such awful gallery is per polygon mip-mapping with unstable mip selection.

All features supported by the engine can be used simultaneously, with only one rendering pass required for any combination. They sure feel better than MX, but I am not benchmarking 2D. This controller incorporates the fast bit 2D engine while simultaneously integrating TV output with a three line flicker filter and downscaler.

Let me just say if often exposes problems in the style of Trident 3DImage. Its promise of single cycle bump-mapping was not fulfilled.


Please do not send technical questions or requests to webmaster alsc. And since AT3D does not use system memory there is with 4 MB little hope for true color rendering at higher resolutions.

Such artifacts also prevents closer inspection of Alliances Pseudo Bilinear texture filtering. Gouraud shading is done full speed and geometry looks perspectively ok. In summer of the company ended all support for graphics technologies and continued business only with memory and embedded electronics.

Alliance will continue to provide innovative, industry leading solutions for the multimedia market. Texturing however, pomotion so warped it turns your accelerated games into chaos barfed all over your display.

Alliance ProMotion AT3D

alliancf Alliance did not give up on 3d after this disaster and announced another bit architecture: It is not only the monochrome dynamic lighting or stipple patterns used for all but one transparency mode. Conclusion Well, that was fast. I take abandonment of those chips as another proof of how broken the design was.
