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. Sega solicited two competing designs: From the ground up 3dfx planned to build high end 3D gaming board capable to deliver smooth gameplay at x resolution with bilineary filtered textures. Image quality is top notch, Voodoo beats others in drawing atmospheric effects using it’s proper blending, quality bilinear filter and rich table fog. For DOS games, one would analogically copy Glide2x. Retrieved from ” https:

Normally, to use a framebuffer device, one would open it, mmap its display memory and then copy data into it. A problem with them is vooxoo games written for Win9x are not necessarily compatible with modern operating systems, so only a at best period-correct Win9x system can be guaranteed to play all Glide 3dxf properly. I use 2 monitors — one plugged into the Voodoo and one directly to the regular VGA.

The original Voodoo 1, however, only honored 10 bits of these registers, allowing for framebuffers up to pixels wide.

Retrieved from ” https: Finally, for maximum Glide compatibility, one could even use three cards e. After 3dfx came to an end, fanmade drivers tried to solve this problem and make some and later games playable on these cards.

The company’s next and as it would turn out, final product was code-named Napalm. Voodoo Registers — Part 1 Posted on September 7, by graham 6.

Experience With latest official driver vooroo. Testing those two with their last official driver I got these results. 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, note that all overclocking happens at the user’s own risk. By default, windows is set up to reboot on errors This feature, which was introduced by Nvidia a year before, was slowly taking off in and games which use it to a great extent are not optimally suited for 3dfx hardware.

From the ground up 3dfx planned to build high end 3D gaming board capable to deliver smooth gameplay at x resolution with bilineary filtered textures. Vokdoo Rush had the same specifications as Voodoo Graphics, but did not perform as well because the Rush chipset had to share memory bandwidth with the CRTC of the 2D chip.

Some 3dvx had slightly higher clocks to close the performance gap. Dual monitor support with V1.

Its 2D acceleration was very capable. I did a few quick tests with 6 MB version of Voodoo.

The Industry’s Foundation for High Performance Graphics

In March of 15 titles with Voodoo support debut in E3 and audience is shaken by wholly new levels of visual quality. For authentic hardware, VSA can provide the best visual quality in these titles.

Some are raw unsigned integers, some are floating point values, and some are bitfields as you have seen above. This allowed 3dfx to scale solution with versatile chip counts for arcade machine end very high end PC boards from Obsidian. Though at that time few games supported large textures and bit color, and those that did generally were too demanding to be run at playable framerates, the features “bit color support” and “x textures” were much more impressive on paper than bit color and x texture support.

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.


After STB was acquired by 3dfx, Nvidia focused on being a virtual graphics card manufacturer for the OEMs and strengthened its position in selling finished reference designs ready for market to the OEMs. These devices follow the Linux framebuffer device protocol, which essentially consists of being able to open them from an application using open query their properties and change video modes using ioctl and mmap them in order to access linear framebuffer memory.

Despite some shortcomings, such as the card’s dithered bit 3D color rendering and x resolution limitations, no other manufacturers’ products could match the smooth framerates that the Voodoo2 produced.

Texture memory capacity and bandwidth limitations are elevated by proprietary FXT compression. Navigation Main page Recent changes Random page Help.

Now whether this move is to roll out another home console platform or move strictly to the PC gaming space is unknown. The method used to engage the Voodoo’s output circuitry varied vooodo cards, with some using mechanical relays while others utilized purely electronic components.

The acquisition of STB was one of the main contributors to 3dfx’s downfall; [ citation needed ] the company did not sell any Voodoo 4 or 5 chips to third party manufacturers which 3dfxx a significant source of revenue for the company.
