Lowest common denominator? Most developers design software for
hardware that *should* be available by the time the product hits,
making their code state of the art...note that this group does not
contain a certain G. Crammond. ::))))

Before you buy.
That may be true, but it's not a game and that's what counts. Developers
develop for the lowest common denominator, and that's not the Geforce.

... then we'd all be playing the same game over and over and over with
no reasons to upgrade. That's a bit silly :P

I haven't seen this particular demo, but I'm sure it's impressive.

Ah, I see, then probably vertices, not polygons.

Three vertices form a triangle and a variable number of
triangles form a polygon. So, yes and no.
Regardless, I was just curious as to how close their demo
comes to the marketing BS listed in their product brochures.
So, assuming it is rendering 150,000 vertices at the frame
rate of 24 frames per second, we get a triangle rate of
1,200,000 triangles per second. Sounds impressive until
you compare it to their claimed specs:
GeForce 256: 15 million triangles per second
GeForce2 MX: 25 million triangles per second
GeForce2 GTS: 25 million triangles per second
GeForce2 Ultra: 31 million triangles per second
I'd say you are about 276 fps short of the above at a
minimum.

Sorry, but it is vertex, not vertice, plural vertexes
or vertices.
As for your math, you are mistaken. In general, the
best you can do in D3D is N + 2 vertices for N triangles
when specifying a 3D surface, which is all your creature
is composed of.
> 150,000 * 24 * 6 = 7,200,000 * 3 = 21,600,000
That is V/F * F/s * T/V = T/s, why did you multiply it
once again by 3?
Regardless, I assure you that the numbers provided by
Nvidia marketing are inflated by at least a factor of 3.
For this particular application it would appear you are
getting 1.2 - 3.6 million triangles per second depending
on the method used to specify the vertices.

Peak performance can actually be achieved, but under certain
circumstances. There's a demo that shows 14.4(or something) Mtris for
my GF1 DDR. All it's showing is a bunch of spirals, though.
But to think that 15Mtris is going to be achieved no matter what, in
all circumstances, with lighting, texturing, high resolutions, et.c.
is well... naive. Naive and silly.
Well it's always food for an nVidia bashing binge at any rate.
