Alliance ProMotion AT25/3D Driver
Designed to enable a Alliance ProMotion AT25/3D class of realistic and highly interactive 3D games, Voodoo Graphics offers expanded capabilities above and beyond the basic 3D functionality that will be found in commodity Windows and multimedia accelerators.

Major consumer and coin-op OEMs and developers have announced support for the chipset. The support we're receiving from the industry indicates our course of action is the right one.
In the coin-operated entertainment market Data East and Jaleco have announced support and are developing next generation arcade games utilizing Voodoo Graphics. Voodoo Advantage "All of the graphics processors that have been introduced Alliance ProMotion AT25/3D the PC barely meet the basic requirements for 3D," said Gary Tarolli, vice president and chief scientist, 3Dfx Interactive. When combined Alliance ProMotion AT25/3D our performance capabilities developers can produce really cool, interactive game experiences.
To achieve elementary 3D functionality, a graphics chip needs to support perspective correct polygons with point sampled texture mapping, Z- and double-buffering, Gouraud shading capabilities and standard VGA resolution.
In addition, the chipset delivers realistic imagery through sub-pixel correction, alpha blending, and anti-aliasing. Most importantly however, unlike other multimedia accelerators that suffer significant performance degradation when available 3D features are used, Voodoo Graphics was designed to simultaneously offer all of these features at real-time Alliance ProMotion AT25/3D rates. Voodoo Graphics also supports special effects for even greater game impact. These include per-pixel effects such Alliance ProMotion AT25/3D fog, translucency, and transparency, texture compositing, a variety of lighting techniques, texture morphing, animated textures, and reflection mapping.
It is not only the monochrome dynamic Alliance ProMotion AT25/3D or stipple patterns used for all but one transparency mode. Even specular highlights are done via stipple mask. All texture formats from palletized up to are supported. True color textures are full speed and true color buffer is also possible with a small performance penalty.

However, at such depth only palletized textures may be blended "properly". And since AT3D does not use system memory there Alliance ProMotion AT25/3D with 4 MB little hope for true color rendering at higher resolutions.
Could it mean AT3D is tiling the scene? Frankly, I have no idea, datasheet also mentions Z-buffer compression, but the card does not Alliance ProMotion AT25/3D like if it has more memory than others.
Gouraud shading is done full speed and Alliance ProMotion AT25/3D looks perspectively ok. Texturing however, is so warped it turns your accelerated games into chaos barfed all over your display. Perspective correction might have been very well implemented without performance penalty, but somehow at Alliance ProMotion AT25/3D end all important textures are not adjusted.

It reminds me of certain quadrilateral texturing chip trying to render triangles. Such artifacts also prevents closer inspection of Alliances Pseudo Bilinear texture filtering.
Let me just say if often exposes problems in the style of Trident 3DImage. 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.
Modern art lovers should enjoy the impressive gallery. That is the fun of early 3d accelerators.
This is with last official driver which Alliance still offers on their web for download. Even if the basics of textured polygons worked properly the AT3D would not get high image quality marks. Alpha blending is usually done with stipple patterns and quality of bilinear filter escapes me because of all Alliance ProMotion AT25/3D warping. The last thing I can deduce from Alliance ProMotion AT25/3D awful gallery is per polygon mip-mapping with unstable mip selection.

Results Performance is not the worst, but it is not impressive either. Usually AT3D fails to deliver on the promise of 30 frames per second at xx I was too disgusted to measure games again, though. Conclusion Well, that was fast.
