Ok, sure.


Scene dis: solid color sphere on solid colored ground.
Software: Imagine 1.1
Render: Ray-trace with shadows.

A3000/25.......................00:20:02
A2000/50MHz GVP 030/882........00:10:59
A3000/Progressive 040..........00:09:15 (Copyback ON)
A2000/RCS Fusion-Forty.........00:06:30 (CopyBack ON)

Note: this was the *only* test I was able to perform where I was
      able to make a comparison with the Progressive board. These
      were the results but I would hardly call one rendering
      conclusive.
---------------------------------------------------

Scene dis: a garden scene (Exploded_Garden).
Polygons: 73,104
Software: Imagine1.1
Render: 24 bit Raytrace with shadows.
Resolution: 768 x 482 hi-res x=6 y=7
Anti-Aliasing: Full (0)
Depth:10


A3000/25.......................32:27:55
A2000/RCS Fusion-Forty.........09:30:00

..and it may interest some raytracers who like to preview
their work in _scanline_ before a final raytrace:

A2000/RCS Fusion-Forty (same file,scanlined)...00:13:34 (!)

..for me, this figure is very important. Preliminary scanline 
rendering can take upto 2x the availiable memory required to raytrace.
To scanline this file, I required 22megs (the Fusion40 had 32megs
onboard) whereas to raytrace, I only needed 12megs Ram. 

---------------------------------------------

Better rendering speeds will be possible once software packages 
have been optimized for the 040. 

----------------------------------------------

Presently, I'm working with the Broadcast version of Caligari
on the 040. If anyone requires information on Caligari's 
performance, I should have a good idea within a week or so.
Preliminary tests have shown me that Caligari's _Q(uick)Render_ is
atleast 2x as fast (compared to A3000/25) and the realtime response
of a full (wireframe) representation of the object is much smoother
for complex objects.
