The 3dfx Voodoo 5 Incarnate
Up close and personal with 3dfx's next generation product

By Dave "Davo" Altavilla and Marco "BigWop" Chiappetta


Peter began by explaining to us,  in fair detail, the architecture behind the Voodoo5-5500.  In addition, Peter also covered 3dfx's multi-tier approach to the market including Quantum and the up coming Gigapixel technology.  The Quantum product is targeted to extremely high end 3D visualization requirements for applications like Professional Military Flight Simulators etc.  The Gigapixel technology, as we have learned, is targeted at a broad range of consumer applications as well.  So, as you can see, 3dfx is going after the entire "pie" here, not just a piece.

Marco interjected...   "Isn't the 64mb on the 5500 an effective 32mb because it's divided per chip?"...before he could finish the question, Peter covered his ears and screamed, "DON'T SAY IT!!".  He knew what we were getting at though.  Peter explained to us that the memory is in fact a unified 64MB on the board.  To make things simple, basically, 32mb is given to each chip for texture storage, as that is THE ONLY information that has to be duplicated for each of the VSA-100 chips on any particular board.   Vertex data for example IS NOT duplicated for each processor.  With texture compression becoming more prevalent, and 3dfx's ability to support DXTC and FXT1 in hardware, duplicating texture information isn't as big a deal as it use to be.  Just to ease some minds, Q3 running at 800x600 with motion blur and 4xFSAA enabled was SILKY smooth.  Also, remember we were looking at pre-production hardware with early drivers.  

Peter also reminded us that FSAA will be an "out of the box" feature immediately available to all users and developers for that matter.  T-Buffer Effects (Motion Blur, Depth of Field, Soft Shadows and Reflections) all have to be supported at the game developer level.  However, the beauty of the VSA-100 architecture is that the T-Buffer allows the game developer to implement these features very easily.  In the end, 3dfx is targeting a new level of immersion for the end user and exponentially higher quality end product results for the Game Developer.  The essence of all these features is to bring gaming to a more realistic level.  Having experienced the effect these features have first hand, there is no denying the impact...it was superior to anything we have seen to date.

The Demo

Then Peter cued our big bad friend PT to launch the demo...  Marco and I were jockeying for position as to who could get closest to the 20" inch Sony Monitor they had set up for our viewing pleasure.  This was exciting stuff.  PT was running a the Voodoo 5 in special "road-ready" Pentium 733 with 128MB of RAM.  The first thing PT launched was Quake 3 Arena... what a surprise. 

Motion Blur

What was a total surprise was the fact that PT fired up a version of Quake 3 that had been modified to support the Motion Blur effect!  Peter told us that this took an Engineer at 3dfx no more than a few days to do and was very easy to accomplish.  He also pointed out that it was done by an Engineer, not an artist, so even though the effect was impressive, the possibility is there for an even greater improvement.

Here are motion blur shots taken by 3dfx.  These are not the actual in game shots from our demo but the effect was exactly the same.  These are large JPEG images with little or no compression, so if you are bandwidth deprived, be prepared to wait during download.


Believe us when we tell you, that these picture don't even come close to doing the live experience justice.  The effect was VERY cool during game play.  Marco and I were extremely impressed.  A while back, AGN interviewed a few webmasters about their thoughts on the T-Buffer effects.  Marco gave an answer that we feel provides a good analogy as to why screenshots really DO NOT do Motion Blur justice.  Pop a tape in your VCR of any movie with some high speed action and pause it as something is flying by your screen.  Do that and you'll see what we're talking about!


The next demonstration PT launched into was FSAA.  Our slack-jaw look widened.  PT was showing us Microprose's Falcon 4, only this time the horizon was defined and crisp.  There were no jagged lines anywhere including the surrounding scenery, the plane and even the pilot within.  Also equally impressive was the total lack of "swimming textures".  This is an especially annoying thing for most folks.  Ever watch a textured object go by in a game and as it moves across the screen and changes its angle to your viewing position; all the while those beautiful textures are undulating all over the object?  How unnatural, right?  Believe it or not, your eyes get used to this garbage!  Once PT hit the FSAA toggle button, all the texture swimming stopped in its tracks.  It was fantastic and we will never look at a game without FSAA the same way again.  Damn 3dfx for ruining things on us!  They better release Voodoo 5 soon!

PT then broke into FSAA demonstrations on various games such as Homeworld, Lucas Arts' Pod Racer, etc.  Some demos were running at 800X600 and some at 1024X768.  The Kittyhawk demo in particular was very impressive, it was two 15,000 poly models of an airplane spinning on each side of the screen.  One had 4xFSAA enabled and the other didn't. Both were running at 1024x768. The difference was amazing, even at a fairly high resolution, the aliased plane would have fine lines vanishing as it spun around, something we're all used to seeing but hardly pay any attention to.  When you see the same exact model anti-aliased the "texture popping" disappears, which is again something that has to be seen to be appreciated.  Peter Wicher was very specific about the fact that 3dfx does not advocate dropping resolution just because you are running FSAA.  They are targeting their product to support FSAA with 32 Bit Color and 1024X768 resolution, with a silky smooth frame rate.

Here are a couple FSAA screen shots to illustrate the effectThese are uncompressed TGAs and are zipped up for smaller file size and easier downloading .  The reason we are not posting JPEG shots or thumbnails of these, is because image compression and image size reduction introduce a fair amount of distortion into a given scene.  These files are 500+K and 2MB+ in size, respectively.

To really experience FSAA , you need to see it live on a platform with excellent frame rate.  The Voodoo5 delivered this and it was damned impressive.

In addition, take a look here, if you would like a refresher on Soft Shadows and Soft Reflections.


Do we have a winner?

Our visit with Brian and the gang sure was exciting and really opened our eyes to what the future holds for 3dfx.  The Voodoo 5 impressed us as a product that will live up to the hype and marketing that has surrounded this new technology for almost the past year.  FSAA on the Voodoo 5 was so good we can never go back to non FSAA supported games and be truly satisfied.  Motion Blur was more than just a bell or whistle.  It was a real improvement in our level of immersion and sense of speed.  3dfx surely has a winner on their hands with Voodoo 5.  We can't wait to get our hands on review product! 

Many thanks to Brian Burke, Peter Wicher and PT Barnum, of 3dfx, for their time and hospitality during our visit with them in NY.  We really appreciated the "open door" environment they have created within their company and their on line community support.
