Alliance ProMotion AT3D 3DFX Driver
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 frame rates. Voodoo Graphics also supports special effects for even greater game impact. Alliance ProMotion AT3D 3DFX
These include per-pixel effects such as fog, translucency, and transparency, texture compositing, a variety of lighting techniques, texture morphing, animated textures, and reflection mapping. These features let game developers deliver the most realistic interactive entertainment on the market.
On perspective correct, texture mapped, Z-buffered, filtered, LOD MIP mapped, fogged, alpha blended, pixel triangles Voodoo Graphics delivers more than 45 megapixels per second fill rate and overtriangles per second polygon rates on a Pentium The first chip, pixelfx, Alliance ProMotion AT3D 3DFX the primary graphics Alliance ProMotion AT3D 3DFX and contains interfaces to the PCI bus and companion texture processing unit, texelfx.

Alliance ProMotion AT3D 3DFX The Company designs, develops, and markets its products to the desktop and portable computing, networking, telecommunications and instrumentation markets. Alliance manufactures many of its products using advanced 0. 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 the warping. The last thing I can deduce from such 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.
Alliance had more plans with this architecture. I take abandonment of those chips as another proof of how broken the design was.
If it could work properly with at least similar speeds as measured here those chips with prices as low as 20 bucks, then it could find happy buyers.
