The ProMotion core meets the most demanding 2D and video requirements, featuring a fast bit internal drawing engine; DVD and live video input port VMI ; video playback acceleration, including full bilinear filtering; and hardware gamma correction and chroma correction. Gouraud shading is done full speed and geometry looks perspectively ok. They sure feel better than MX, but I am not benchmarking 2D. Specifications promised a fine piece of 3D accelerator, press announcement and datasheet would make you think you cannot go wrong.

Alliance will continue to provide innovative, industry leading solutions for the multimedia market. The ProMotion core meets the most demanding 2D and video requirements, prmotion a fast bit internal drawing engine; Alliancf and live video input port VMI ; video playback acceleration, including full bilinear filtering; and hardware gamma correction and chroma correction. Texturing however, is so warped it turns your accelerated games into chaos barfed all over your display.

And then you fire up the card, play games and everything is broken.

Alliance had more plans with this architecture. Conclusion Well, that prpmotion fast. It is not only the monochrome dynamic lighting or stipple patterns used for all but one transparency mode.

Alpha blending is usually done with stipple patterns and quality of bilinear filter escapes me because of all the warping. And since AT3D does not use system memory there is with 4 MB little hope for true color rendering at higher resolutions.

Perspective correction might have been very well implemented without performance penalty, but somehow at the end all important textures are not adjusted. Normally such image quality would disqualify the card from benchmarks, but just to get some idea of it’s performance Promotiom measured few games that were recognizable. Except for historical information contained herein, the above constitutes forward looking statements; actual results could differ materially from allixnce 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 Aoliance and available through the Company’s home page: Usually AT3D fails to deliver on the promise of 30 frames per second at xx This controller incorporates the fast bit 2D engine while simultaneously integrating TV output with a three line flicker filter and downscaler.

That is the fun of early 3d accelerators. Alliance did not give up on 3d after this disaster and announced another bit architecture: Promottion check AT3D arrived in summer and Alliance was showing it off as a true second generation 3d accelerator. AT3D delivers true state-of-the-art 3D acceleration, including on-chip hardware allixnce setup, to bring the fast frame rates of console gaming to the PC platform.

But only after you see AT3D in action, you will know how much broken can things be. I was too disgusted to measure games again, though. I take abandonment of those chips as another proof of how broken the design was.

This is with last official driver which Alliance still offers on their web for download. Additional Company information can be found on our home page: All texture formats from palletized up to are supported. Any 3d rendering scenario should be performed in one pass.

Results Performance is not the worst, but it is not impressive either. It sets memory clock 60 MHz and it is reasonable to expect clock of the nm chip to be synchronous. The architecture is optimized to provide fast frame rates att3d ensure maximum interactivity.

Even if the basics of textured polygons worked properly the AT3D would not get high image quality marks. Alliance got more attention from gamers when their graphics cores were chosen for At3c Rush boards supporting 3D only chipset of 3Dfx.

However, at such depth only palletized textures may be blended “properly”.

The chip also supported odd sizes of 1. They are still alive today, albeit they moved away from semiconductors.

Such artifacts also prevents closer inspection of Alliances Pseudo Bilinear texture filtering. Could it mean AT3D is tiling the scene? Well, that was fast.
