ALLIANCE SEMICONDUCTOR AT25 + VOODOO RUSH (DUAL BOARD) DRIVER
For DOS games, one would analogically copy Glide2x. To get games which were originally made for Voodoo Graphics to work with Voodoo2 boards, one can use the following SST variables in the autoexec. The RAM banks are on independent bit buses. The chipset was rich in features, boasting perspective correct texture mapping, bilinear texture filtering, level of detail MIP mapping, sub-pixel correction, polygonal-based Gouraud shading and texture modulation.
It natively supported Direct3D 5 and was notable for supporting all of its required features with adequate speed, unlike previous 3D chipsets such as S3 Virge and Matrox Mystique. Glide was essentially a subset of OpenGL, with no support for features deemed unnecessary for PC gaming at the time, and for some functions not supported by the SST1 architecture. OpenGL games were initially only supported through the use of MiniGL, which was an OpenGL driver with only the necessary functions implemented for a specific game, most notably Quake engines. Unfortunately the passthrough impacts 2D quality because of the signal passing through additional circuitry that may not be of optimum quality. High resolution GUI modes are most Alliance Semiconductor AT25 + Voodoo Rush (Dual Board) affected. Thanks to 3dfx's efforts with game developers and publishers and the excellent performance of their solution, the company's technology was quickly adopted as the de-facto standard in PC 3D gaming.
Voodoo 1 enjoyed lengthy support from game developers.
Despite only supporting resolutions as high as x x without the usage of Z-buffering and bit color depth, the card was usable with games into Bottom line: The card's prime use case would be early statically-linked Glide games in DOS that depend on the first Voodoo chipset. Later games, starting with ca. Cards with higher than 4 MB are a trade-off: Both offer somewhat smoother frame rates in games with more texture memory usage, such as Unreal and Quake 2.

Some cards had slightly higher clocks to close the performance gap. The cards also sometimes weren't fully compatible to existing games, leading to specific Voodoo Rush patches for some games, e.
Tomb Raider. The AT3D chipset has rudimentary 3D functions which can be activated, meaning that Rush cards that feature it have two 3D chipsets. Primarily a curiosity. Despite that, the cards may be potentially useful in fringe cases like in a system with only a single available PCI slot that does not support a Banshee or Voodoo 3 because of a weak power supply or weak voltage regulators. They shouldn't be difficult to acquire since the demand is not as high as for other 3dfx cards.
The clock was increased to 90 MHz, almost doubling the performance compared to Voodoo1. Performance in games utilizing the Voodoo2's second texture unit by means of single-pass multitexturing is further increased. Single-pass trilinear filtering was possible as well. The cards also support SLI Scan-Line Interleavea technique which allows 2 cards to be run simultaneously and draw the lines of the image in turn, boosting performance and enabling a resolution of up to x With one card installed, up to x is possible regardless of memory.

It is also possible to use a modified floppy drive cable. Following the same principle as the Voodoo1 there are three independent bit RAM buses, one for the frame buffer processor and one for each TMU.

So even though there are technically 4 or 8 MB of texture memory on a card effectively there are only 2 or 4 MB available for textures. With SLI this amount does not grow, instead the textures will be copied two more times. Voodoo2 still requires the passthrough cable and use of a separate 2D card. However, Alliance Semiconductor AT25 + Voodoo Rush (Dual Board) chipset does have some 2D features and there is a driver for Linux that allows one to use Voodoo2 as a GUI accelerator. The Voodoo2 remained the standard for PC 3D accelerator cards throughout The iconic Voodoo2 SLI setup holds nostalgic value for some people.
Voodoo2 SLI is viable for almost all Glide games, and has the advantage over Voodoo 3 that it can play more Glide games originally only designed for Voodoo1, with Alliance Semiconductor AT25 + Voodoo Rush (Dual Board) environment variable configuration. Weak points include occasional slight stutter in texture intensive games due to texture trashing and possible image quality problems resulting from the passthrough design. It is clocked at MHz, meaning that the midrange Banshee was actually slightly faster in then prevalent single-textured games than the high-end Voodoo2, yet clearly falls behind in games utilizing multi-texturing. Its 2D acceleration was very capable.
It also was the first to have the "bit" 2x2 filter see below. As such they are not ideal gaming choices, although they can be still useful for some games. Following the buyout of STB, 3dfx was now manufacturing their own cards. The chip was capable of bilinear texture filtering, perspective correction, using palletized textures for saving memory, alpha-blending, z-buffering limited to x pixels and a few other neat tricks not too common in the 3D world back then.
