The difference is perhaps so small because the card cannot deliver high framerates in newer games even if it had enough texture memory. The Voodoo2’s third chip was a second TMU that allows a second texture to be drawn during the same graphics engine pass, and thus with no performance penalty. Voodoo3 was a series of computer gaming video cards manufactured and designed by 3dfx Interactive. Hardware , Retro Glide , Hardware , Retro. This massive raw performance made all the difference.

Common texture formats up to 16 bit are supported, up to x resolution.

Later games, starting with ca. However, in the early 3df of the 3D graphics card, Direct3D and OpenGL implementations were either non-existent or, at minimum, substantially less mature than today, and computers were much slower and had less memory. The mechanical relays emitted an audible “clicking” sound when they engaged and disengaged.

Voodoo Registers – Part 1

The and models offers performance exceeding Voodoo2 SLI in certain environments. This also further alienated 3dfx’s remaining OEM customers, as they had a single source for 3dfx products and could not choose a CEM to provide cost flexibility. Finally, for maximum Glide compatibility, one could even use three cards e. The Glide library is a low-level rendering and state management subroutine library that serves as a thin layer over the register level interface to the 3Dfx Interactive family of graphics accelerators.

But first a warning about 3dfx screenshots. Sales of the Voodoo Rush cards were very poor, and the cards were 3dfs within a year.

By clicking on the image a highlighted are will zoom in to show obvious pattern. Voodoo drivers are now placed in Windows Fl folder where in Windows 9x they are placed in Windows System.


Webarchive template wayback links All articles with unsourced statements Articles with unsourced statements from November Voodoo is close to single cycle performance and sustains 30 millions bilineary filtered textured pixels per second in non trivial scenarios. In August 3dfx abandons plan for own exclusive card as falling memory cost make board manufacturers accept unusually high price of 3d only Voodoo Graphics.

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.

So I finaly put together a voodoo1 machine. This offered better quality than running in pure bit mode. Of course, specific framebuffer device vkodoo are free viodoo implement more, custom ioctls.

As long as a texture has similar color components the image quality should not suffer. Performance Upon it’s release power of Voodoo was so shocking that it was hard to imagine a need for something more in the future.

Voodoo2 – Wikipedia

At that time, 3dfx’s marketing was centered around speed, but to demonstrate that the image quality was still better than their last year’s high-end setup, they invented the term “bit”, describing the added 2×2 box filter that masks dithering.

It was also common for game developers to put 3dfx logos on their games’ boxes, leading to misconceptions for a decent amount of games ostensibly supporting Glide which actually do not at all, or only provide a special MiniGL driver for 3dfx cards. Near the end of3dfx released the Bansheewhich featured a lower price achieved through higher component integration, and a more complete feature-set including 2D acceleration, to target the mainstream consumer market.


The register file of the Voodoo chipset is essentially organized as a large set of state registers with a few command registers interspersed amongst them.

Unfortunately the passthrough impacts 2D quality because of the signal passing through additional circuitry that may not be of optimum quality.

Here are a few tips I can give, based on web docs and my own experience, to possibly help you guys. When using this method, it is important to install the drivers in ascending order, so that games which access the drivers in the Windows folder use the newest gk card.

A notorious example for this is Unreala game that was geared towards software rendering at first, but had a Glide renderer added during development as soon as it 3ddfx clear that Voodoo would come out as the best 3D accelerator. Unsourced material may be challenged and removed.

V2 SLI which will automatically engage when Glide is chosen in games.

Screenshots from this demo emerged around November and the actual program was released in Decemberafter 3dfx went foodoo. Articles needing additional references from November All articles needing additional references All accuracy disputes Articles with disputed statements from December Go to the 3dfx Drivers Original for the 3dfx Released Drivers.

PCI and AGP versions of 3dfx hardware were considered to perform virtually identically with contemporary games, but testing has shown that later games can largely profit from higher bus bandwidth.
