Basically, if you've learned one thing from these early reviews: processor
speed _still_ matters a great deal.  Something I've been telling people
over and over, but even I was a litlte surprised at these results.

The Monster Truck/Hellbender comments on a P100 were quite disappointing-
cripes, it doesn't sound as if they're beating the Virge that much with
these two!  After numerous discussions with 3DFX employees, I am a little
underwhelmed- we were led to believe a P90-100 would be enough to get 25+
fps on _everything_.  And heck, it's not like most of the games were
graphical powerhouses.  If the Voodoo can't run them all at 30fps, it's a
sad comment on PC 3D (hardware and software) and the PC architecture in
general.  It will be interesting to see how the 3D Blaster fares.  Very
early I know, but I was a little surprised with the Voodoo's much-touted
power, I wouldn't think you would need a P166 just get a consistent 30fps
on everything.

A helpful equation to keep in mind?  Take any frame rates on a system a rep
from a 3D company gives you, and HALVE them. That's your _real_ frame rate.

Respectfully, lets wait till we here some others reviews before we "Rush to
judgement ;)" Anyway, I think its been hinted about that a 133 would probably
be the realistic minumum for full use of a 3d accelerator. When I get mine
tomorrow (doubtful) or Monday, I will post *very* complete and detailed
benchmarks. My machine is a P-200, so I assume Ill be getting full frames from
these games. If there is slowdown on this puppy, then I think its time to
complain.

Actually, looking back at that review the user had a Neptune chipset, and
his 256k cache was probably not pipeline burst, not to mention non-EDO
memory.  That's a P100, but likely quite a slow P100 by today's
comparisons.  I imagine a good P133 EDO PB cache system should perform
significantly better, more so than just the clock speed increase would
indicate.  Anyone with a decent P133+ system, post your review when you get
it!

Right now they don't seem to accelerate anything but how fast money

Because the 3D cards offer other features besides raw speed, they look
much better at the same resolution.  Realize that resolution isn't
everything, which has been the case so far with PC graphics mostly.

>It seems like they try to much and achieve to little.

A p200 could NOT get but around 2fps with all the same options enabled
where the OR3D gets 60-70fps on a P166 with all options enabled.
Again, it's about looks, not just raw resolution as well.

There is a drastic difference between the two, get the DirectX2.0
demos and play around with the color modes, and you'll see what I
mean.

It's actually best if a 3d card is "scalable", meaning the graphics
performance scales with the CPU, because the CPU does and will always
share the task of rendering complex graphics.

:), is true somewhat.

I'm debating that myself.

Dave, you know my home system. I rushed over to work after reading these
messages at 1 AM, and sure enough the package was sitting on my chair.
I've been out of town so I had no idea, but the timing was perfect!

P5-133, Triton-I chipset, 512k PBC, Matrox Millenium 2MB.

I have the full version of Monster Truck Madness, so I want to comment
on that first. Without the 3Dfx card, 640x400 mode is unplayable on
my machine. With the 3Dfx card, at 640x400x16 bit mode with all
3D features on it looks really close to 30FPS all around. I don't
know how to get a frame rate counter, but it is definitely smooth.
I'd say 25-30fps. It beats 640x400x8 handily on my machine. And it
looks really good. There are some strange visual artifacts on the
horizon, but overall the game looks great and runs *fast*.

Descent 2: Quartzon is also much faster than software at 640x400x16.
I can't get the "framerate" code to work, so I don't know the exact
fps but it is over 30fps in most rooms so far.

Conclusion: this card is obviously faster than software.

However, there *is* a good Win95 benchmark with FPS on the CD.

1. Copy the r3ddemo\wiz folder from the CD to your hard drive.
2. Make sure you mark all the files you copied as read/write or
   the demo will not run. To do this, just select all the files
   right click them, select properties, and turn OFF the read
   only flag.
3. Double-click on WIZ.EXE, wait til it starts up and you are
   in a 3D room.
4. Press CTRL+P.
5. it will say "INIT", wait, then show you a FPS rate.

This gives you a good framerate counter which we can compare
to see how much effect processor has on this card.

I get 29.9 FPS from the starting point. Interestingly, CTRL+M turns
mipmapping on/off, and CTRL+B turns bilinear filtering on/off. Neither
one has any real effect on the frame rate.

Yes.  You are correct.  My system is on the very low end of the
performance spectrum when compared to other P100's (Remember I'm an
overclocked P90.  The cache is definitely not pipeline).  I purchased my
system over two years ago when a P90 was the fastest system around.  So,
by today's standards, I have a pretty pathetic system as far as a
Pentium system is concerned.

Anyway, I thought that my system would be a good system to review the
R3D for that very reason.  After reading my review, there is no reason
to believe that their system will perform any worse.  Of course, from my
perspective, that sucks. ;)

Type "framerate" in the middle of playing a game.

I can tell you right now that my P100 runs faster than a non-accelerated
200 mhz Pentium Pro at 640x480x16 on every demo that came with the
card.  Plus, the graphics look better.  The $300.00 upgrade was
definitely worth it to me.

Now all I need to do is save up and GET a PPro to really make this thing
fly like an SGI. ;)

It's a good question.  Generally, a 3D accelerator requires some minimal
performance out of the CPU before you get useful frame rates out of them.
On the other hand, it would require a _very_ fast CPU before you could
get the same image quality that you would out of most 3D accelerators.
I would estimate you would need a 2 GFLOP+ CPU to achieve the same image
quality and frame rate you would get out of a 3Dfx Voodoo Graphics chip
set.

Voodoo Graphics was targeted for people with a Pentium with a reasonable
bus, say a P100 Triton based system.  I ran stuff on a P75 with a Neptune
PCI chip set for awhile, and Voodoo was always faster than software.

There are many good reasone why 3D accelerators don't support 8bpp modes.

I  used to have an Intel Plato (Neptune ?) motherboard with a P90 and
256K async cache (pre Triton). I upgraded it to an ASUS P55TP4XE
motherboard (Triton 1) with 256 k PB cache and that alone made my 3D
Bench score go from 83 to 100 (20% increase). When I then swapped the
P90 for a P133 my score went from 100 to 125 (another 20%). This
seemed to make a big difference to SVGA like Screamer were unplayable
in SVGA before the upgrade.

Anyway the point is that the motherboard alone can make a big
difference.

I can't wait to get my Righteous 3D but us poor suckers in the UK have
to wait until 14 October for it to be released :-(

Unaccelerated video may run say 10fps. Accelerated video will set to
to say 15fps. This is based on the same clock.

True. Programmers or rather, graphics artistes rarely uses 32K colors.
They may only use 200 colors but think, they are using shades ouside
the 256 colors boundary. Only at 32K colors can they get the shade
they want and you want. Get the idea?

It's just that hardware advances does not parallel software

It's the lack of a little slab of silicon known as the geometry processor.
As far as I know, not a single user-level 3D card for PCs supports any type
of geometry processing, thus leaving your CPU to do all that work.  There is,
however, the GLINT Delta (from 3DLabs) which does a great deal of geometry
processing.  However, it's incredibly expensive.  Still, I'd hedge my bets
that by the middle or end of next year, we should see 3DLabs' 'low end'
Permedia paired up with the Delta for about US$400.  One more advantage to
the Delta is that it's scalable:  you can add more than one Permedia (or
GLINT 500TX, depending upon which card you bought) for greatly increased
performance.

Your Direct3D test should be much higher than that.  See the threads on

From what a rep from 3DFX told us her, it's simply geometry setup portion-
something the Rendition and 3DFX already do.  Geometry set-up is but one
part of the pre-rendering stage. it's not a true geometry processor.

Actually no, the Delta version is only $100 more than the non-Delta
version.

To use Fastvid on the Voodoo is not that easy. If you don't supply any
parameters, Fastvid searchs for the LFB (linear frame buffer) of your
2D card. It will completely ignore your Voodoo.

What you have to do is to make out the memory range of the Voodoo and
set Fastvid parameters accordingly.

It is still unknown if Voodoo is compatible to Write Combining.

I don't think Write Combining will have that much of effect on the
Voodoo because after the textures have been loaded up there is not
much bandwidth used, unlike 3D games on 2D cards.

I first want to say how rewarding it is to read all your
reviews after having worked on the design of Voodoo Graphics
(the chipset on the Orchid Righteous 3D board) for over two years.
I am one of the founders of 3Dfx and one of our goals was
to deliver the highest quality graphics possible to the PC gamer.
It was and still is a very risky proposition because of the cost
sensitivity of the marketplace.  But your reviews help convince
me that we did the right thing.

I thought I would share with you a little bit about what is
inside the 3Dfx Voodoo Graphics chipset.  There are 2 chips
on the graphics board.  Each is a custom designed ASIC containing
approximately 1 million transistors.  Although this number of
transistors is on the order of a 486, it is a lot more powerful.
Why?  Because the logic is dedicated to graphics and there’s a
lot of logic to boot.  For example, bilinear filtering of
texture maps requires reading four 16-bit texels per pixel (that’s
400 Mbytes/sec at 50 Mpixels/sec) and then computing the equation
red_result=r0*w0+r1*w1+r2*w2+r3*w3 where r0:3 are the four red
values and w0:3 are the four weights based on the where the pixel
center lies with respect to the four texels.  This is performed
for each color channel (red, green, blue, alpha) resulting
in 16 multiples and 12 additions or 28 operations per pixel.  
At 50 Mpixels per second that is 1,400 Mops/sec.  The way this
is designed in hardware is you literally place 16 multipliers
and 12 adders on the chip and hook them together.  And this is
only a small part of one chip.  There are literally dozens of
multipliers and dozens of adders on each of the two chips dedicated
only to graphics.  Each chip performs around 4,000 million actual
operations per second, of which around one third are integer
multiplies.  These are real operations performed - if you were to
try to do these on a CPU (or a DSP) you must also do things like
load/store instructions and conditions. In my estimation it would take about
a 10,000 Mip computer (peak) to do the same thing that one of our
chips does.  This is about 20 of the fastest P5-200 or P6-200 chips
per one of our chips.  Not exactly cost-effective.  So if you want
to brag, you can say your graphics card has approximately the same
compute power as 40 P5-200 chips.  Of course, these numbers are more
fun than they are meaningful.  What is meaningful in graphics is
what you see on the screen.

Now of course, if you were writing a software renderer for a game,
you wouldn’t attempt to perform the same calculations we perform on
our chip on a general purpose CPU.  You would take shortcuts, like
using 8-bit color with lookup tables for blending, or performing
perspective correction every ‘n’ pixels.  The image quality will
depend on how many shortcuts you take and how clever you are.  
Voodoo Graphics takes no shortcuts and was designed to give you
the highest quality image possible within the constraint of 2 chips.  
As your reviews have shown, it is evident that you can see the
difference in quality and performance.

Now I am sure the subject of triangle setup and geometry calculations
will come up sooner or later in this newsgroup.  Let me make a
preemptive strike and answer your questions before you ask them.  
There is no geometry acceleration on the board, where geometry is
defined as geometric transformation and lighting.  In the Wizard’s
tower demo you see lighting being applied to texture maps through
the use of a ‘lighting map’, which is another texture map that
contains the results of off-line radiosity calculations.  This is
not traditional lighting in the OpenGL sense, but is nonetheless a
very powerful method of performing static lighting.  It is becoming
more popular with games and personally, I think its great!  It
requires bilinear filtering AND high fill rates, both of which
the R3D card has.

Now back to triangle setup.  The Voodoo Graphics chipset performs
about 2/3 of triangle setup in hardware.  When designing Voodoo
Graphics I carefully studied exactly what triangle setup our design
required and we placed things that were hard for a Pentium to
perform in hardware and left things easy for a Pentium to perform
out of the hardware design.  Our triangle engine is also very
efficient in that it requires less setup than most (I worked 9 years
at SGI and have a lot of triangle engine experience).  The net
result is that the 1/3 of triangle setup we perform on the Pentium
is not many cycles at all. That is why our triangle numbers are so high.  
With an efficient design, you can afford to use the Pentium to perform
some of your triangle setup.  With an inefficient design, you cannot.  
I know this is a very controversial subject, so I will stop right here.

I hope this answers some of your questions in advance.  Thanks for
buying the board and I hope you enjoy it.  As for the flight sims,
I am waiting for one too, and am anxiously awaiting to see what our
chips can do.  I wrote the original SGI flight simulator and hopefully,
I won’t have to write another one :-}

Did you read my post comparing 3dfx-enhanced Descent 2 framerates on
a P5-100, P5-133, and P5-166?

The frame rate at the start of level 1 without moving the ship was
30.0 on all those machines. The non-accelerated versions came in
at 14.5, 17.25, and 18.75 respectively.

I'm guessing that the direct 3D tunnel demo is not very processor
intensive and relies greatly on the 3D card
maybe a real world app would see a more dramatic increase with the
rightous involved?

Actually.. now that I think about it.. that shouldnt matter.. it might
be the way the tunnel test was coded..
I'm gonna hit send anyway.. hehehe

It sure does, and thanks for the post.  It's not often a company
