Introduzione

Per molti appassionati la scheda grafica 3dfx Voodoo5 6000 ha rappresentato e rappresenta un sogno irrealizzabile, un traguardo più forte del tempo e dell'evoluzione tecnologica. Abbiamo dunque pensato fosse doveroso dedicarle uno spazio attraverso il quale mostrarne le prestazioni con i games attuali (Unreal Tournament 2003) e del passato più o meno recente (Medal Of Honor Allied Assault e Quake 3 Arena).

La configurazione della scheda per i test non è stata delle più agevoli: la Voodoo5 6000, a differenza delle sorelle minori Voodoo4 4500 e Voodoo5 5500, evidenzia infatti scarsa compatibilità con numerose motherboards: bisogna ricordare però che tutti gli esemplari in circolazione sono delle versioni di pre-serie, non avendo mai avuto questo modello una fase di commercializzazione, per cui essi rappresentano in buona parte la realizzazione di un progetto che andava ulteriormente ottimizzato.

Specifiche ufficiali

Di seguito sono riportate le caratteristiche principali della scheda pubblicate da 3dfx sul proprio sito.

General Features	Benefits
Fully integrated 128-bit 2D/3D/Video Accelerator	It's not just for gaming! Voodoo5 6000 AGP enables outstanding 2D and video applications too.
128 MB of Graphics Memory	No, we're not kidding. How about having enough graphics memory to handle 1600x1200, 32 bits per pixel, with full-scene hardware anti-aliasing enabled?
1.32 to 1.47 Gigapixels Per Second Fill Rate	Not kidding about this one, either. The first gigapixel board delivers frame rates beyond belief. Virtually all games are limited by fill rate at resolutions of 1024x768 and above so the higher your fill rate the faster your game will perform.
Real-time Full-Scene HW Anti-Aliasing	Removes annoying jaggies and flashing objects from the image to dramatically improve the visual quality of any title, new or old.
T-Buffer Digital Cinematic Effect: Motion blur	Can be used to smooth motion to improve image quality or to exaggerate motion for special effects.
T-Buffer Digital Cinematic Effect: Depth of Field Blur	Enhances reality by rendering a scene as if viewed through a real lens. Enables artistic depth of field effects often used in cinema, such as blurring all but the most important objects in a scene.
T-Buffer Digital Cinematic Effect: Soft Shadows	Adds soft edges to shadows, giving them a much more realistic appearance.
T-Buffer Digital Cinematic Effect: Soft Reflections	Enables realistic reflections from semi-gloss surfaces like polished wood or stone and stainless steel.
FXT1 and DirectX Texture Compression	Dramatically reduces the size of texture images with no loss in visual quality; higher frame rates and better image quality. VSA-100 supports all five DXTC compression modes. Texture compression is critical for use of 2048x2048 and 32-bit textures.
8-bit Palletized Textures	The most widely used form of texture compressio. As with FXT1, palletized textures enable higher frame rates and enhanced image quality. Graphics cards that do not support palletized textures often experience severe game compatibility problems.
32-bit Rendering	Supports the highest possible image quality for the latest titles.
32-bit Textures	Allows use of the highest quality artwork seen in today's titles.
2k x 2k Textures	Allows you to enjoy the full impact of the most detailed artwork used by game developers; larger textures enable more complex, more stunning images.
24-bit Floating Point Depth Buffer (Z or W)	Virtually eliminates "Z aliasing," or having surfaces that should be visible being occluded and surfaces that should be occluded being visible.
8-bit Stencil Buffer	Improves image quality and realism by supporting a technique widely used by 3D content developers to create complex shapes such as shadows.
350MHz RAMDAC	Allows users to run at insane resolutions and incredible refresh rate --2048x1536 at 85Hz for example.
The industry's most complete API support: DirectX, OpenGL, and Glide	Assures the industry's highest title compatibility.
DVD hardware assist: planar to packed-pixel conversion	Assists DVD titles in running at 30fps without dropped frames.
Windows 95, 98	Allows you to run the Voodoo5 6000 AGP with all popular operating systems.
