3Dfx Voodoo Rush AT3D Driver

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 3Dfx Voodoo Rush AT3D 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, the chipset does have some 3Dfx Voodoo Rush AT3D 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 However, if the graphic chip is at its limit of pixel fill rate or polygon rate, the CPU can try sending geometry data to the graphic chip as fast as it wants, the graphic chip can't produce a higher frame rate anymore.

In this case the frame rate is not determined by the CPU at all, it's the graphic chip that limits it. Now what does this mean to us?

He could not believe that with a CPU which is 3 to 4 times as fast as his, the frame rate would only increase by a few percent. His argumentation was certainly sensible, but he forgot that it could be, that the Voodoo Rush chip is either scaling very slowly or maybe already at 3Dfx Voodoo Rush AT3D performance limit in a small Pentium MMX system.

The same wrong estimation could happen if you look at how the Apocalypse 3Dx scored in the system with the Pentium II However, if you have got 3Dfx Voodoo Rush AT3D system with e. If you want to buy a 3D graphic card, you got to realize the 3D geometry performance of your system. Then you have to know if you want to play Quake, Quake II or any other game that's using this engine.

Forsaken or Incoming aren't either. Videologic's PowerVR chip is another one that scales well, but doesn't score as high, and the same is valid for 3DLabs' Permedia 2.


However, the absolute 3D performance of the Voodoo is what makes it still the best choice for a high 3Dfx Voodoo Rush AT3D system as well. The soon released Voodoo 2 will solve this problem and scale much better. The owner of a mid range to low end system still wants a 3D chip that scores high 3Dfx Voodoo Rush AT3D, but it doesn't matter if the chip scales well, as long as the performance is good in systems with lower 3D geometry performance of the CPU.
