3DFX Voodoo4/5 Amigamerlin 3.0 Graphics Driver
To get games which were originally made for Voodoo Graphics to work with Voodoo2 boards, one can use the following SST variables in the autoexec.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, 3DFX Voodoo4/5 Amigamerlin 3.0 Graphics 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 noticeably 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 The card's prime use case would be early statically-linked Glide games in DOS that depend on 3DFX Voodoo4/5 Amigamerlin 3.0 Graphics 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. The AT3D chipset has rudimentary 3D functions which can be activated, meaning that Rush cards that feature it have two 3D chipsets.
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 3DFX Voodoo4/5 Amigamerlin 3.0 Graphics. 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, the 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
