ALLIANCE PROMOTION AT3D DRIVER

Its promise of single cycle bump-mapping was not fulfilled. I am of course testing pure AT3D board. Perspective correction might have been very well implemented without performance penalty, but somehow at the end all important textures are not adjusted. 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. Conclusion Well, that was fast. Alliance had more plans with this architecture. Specifications promised a fine piece of 3D accelerator, press announcement 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. Many people often say something in early 3D chip prromotion broken, dissing the likes of TridentRage or even Riva Alliance promised all-in-one solution for new multimedia age.

And then you fire up the card, play games and everything is broken. Could it mean AT3D is tiling the scene?

Removing the expansion memory would make the EDO work in single cycle mode rather than interleaved. Additional Company information can be found on our home page: Gouraud shading is done full speed and geometry looks perspectively ok.

Usually AT3D fails to deliver on the promise pfomotion 30 frames per second at xx Alliance had more plans with this architecture.

Alliance got more attention from gamers when their graphics cores were chosen for Voodoo Pfomotion boards supporting 3D only chipset of 3Dfx. The Alliance multimedia accelerators are supported by a robust driver suite which has undergone extensive testing. 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: Alpha blending is usually done with stipple patterns and quality of bilinear filter escapes me because of all the warping.

Texturing however, is so warped it turns your accelerated games into chaos barfed all over your display. It is not only the monochrome dynamic lighting or stipple patterns used for all but one transparency mode. It reminds me of certain quadrilateral texturing chip trying to render triangles.

I take abandonment of those chips as another proof of how broken the design was. Results Performance is not the worst, but it is alliancr impressive either. I am of course testing pure AT3D board. Let me guess, they split the bit bus into two.

Company Information Alliance Semiconductor Corporation is a leading worldwide supplier of high performance memory and memory intensive logic products. Samples are planned for April with volume shipments planned for June This controller incorporates the fast bit 2D engine while simultaneously integrating TV output with a three line flicker filter and downscaler.

Technical specs says that Alliance chips got a special 64 bit bus for fast communication with Rush. 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. Let me just say if often exposes problems in the style of Trident 3DImage.

They sure feel better than MX, but I am not benchmarking 2D. Conclusion Well, that was fast. If it could work properly with at least similar speeds as measured promohion those chips with prices as low as 20 bucks, then it could find happy buyers. However, at 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. Alljance chip also supported odd sizes of 1. Any 3d rendering scenario should be performed in one pass.

The architecture is optimized to provide fast frame rates to ensure maximum interactivity.
