Alliance got more attention from gamers when their graphics cores were chosen for Voodoo Rush boards supporting 3D only chipset of 3Dfx. 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. Big numbers, triangle setup, free per-pixel perspective correction, all the texture formats and blending operations supported, bit video engine and bit memory bus. Alpha blending is usually done with stipple patterns and quality of bilinear filter escapes me because of all the warping. They sure feel better than MX, but I am not benchmarking 2D. Gouraud shading is done full speed and geometry looks perspectively ok. 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:

It is not only the monochrome dynamic lighting or stipple patterns used for all but one transparency mode.
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. 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.
The chip also supported odd sizes of 1. Logo of Alliance is on many memory chips of the nineties. Even if the basics of textured polygons worked properly the AT3D would not get high image quality marks. Well, that was fast. Perspective correction might have been very well implemented without performance penalty, but somehow at the end all allaince textures are not adjusted.
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. Alliance will continue to provide innovative, industry leading solutions for the multimedia promotioj.
Alliance Press Release
In summer of the company ended all support for graphics technologies and continued business promotoon with memory and embedded electronics. Removing the expansion memory would make the EDO work in single cycle mode rather than interleaved.
It sets memory clock 60 MHz and it is reasonable to expect clock of the nm chip to be synchronous. Please do not send technical questions or requests to webmaster alsc. I take abandonment of those chips as another proof of how broken the design alloance. All features supported by the engine can be used simultaneously, with only one rendering pass required for any combination.

Results Performance is not the worst, but it is not impressive either. Specifications promised a fine piece of 3D accelerator, press att3d and datasheet would make you think you cannot go wrong.
And since AT3D does not use system memory there is with 4 MB little hope for true color rendering at higher resolutions.
The architecture is optimized to provide fast frame rates to ensure maximum interactivity.

The Alliance multimedia accelerators are supported by a robust driver suite which has undergone extensive testing. Usually AT3D fails to deliver on the promise of 30 frames per second at xx Additional Company information can be st3d on our home page: That is the fun of early 3d accelerators.
Samples are planned for April with volume shipments planned for June This is with last official driver which Alliance still offers on their web for download. They sure feel better than MX, but I am not benchmarking 2D.

Alliance manufactures many of its products using advanced 0. Could it mean AT3D is tiling the scene? Alliance did not give up on 3d after this disaster and announced another bit architecture: Let me guess, they split the bit bus into two.
Conclusion Well, that was fast. Alliance got more attention from gamers when their graphics cores were chosen for Voodoo Rush boards supporting 3D only chipset of 3Dfx.
Its promise of single cycle bump-mapping was not fulfilled. True color textures are full speed and true color buffer is also possible with a small performance penalty. The Company designs, develops, and markets its products to the desktop and portable promogion, networking, telecommunications and instrumentation markets.
