Just upgraded to a PIII 800Mhz (256Mb) from a Celeron 400 (192Mb). I ran
skyvase before and after here are my results:
Before:
skyvase.pov
1024x768 AA 0.3
168 s total

After:
skyvase.pov
1024x768 AA 0.3
77 s total

I'm stoked!
Isosurfaces, here I come!

I guess this means I shouldn't mention the 1.1 Ghz AMD with 256 MB of RAM
and ATA100 30 GB RAID drives I just configured yesterday ;)

Shame it's my Dad's though, I've already done some quick benchmarks on RC5:
4.1 million keys/s.  No doubt I'll be using it for network rendering of a
night time though >:)

Mwuhahaha!

I'd really like to try some MegaPOV stuff some time, since I've got enough
power now to try all the neat features :)

That would be 2.18181818 times faster then.  I went from a 500MHz to 800MHz
(both PIII) and had 1.8166666 times change.
I did the skyvase.pov too except per the POV-Ray Benchmark way.
The one constant remains, never fast enough.

Try the proximity pattern...that should cure you. ;-)

// disclamer: code below has been typed from memory, may contain errors and

Two or three of those types of isosurface in a scene and my machine grinds
to a halt.

I would add:

global_settings{
   ini_option "+QR"  
   radiosity{     
     count 2000                
     error_bound 0.01   
   }   
} 

so we can get equal rights for memory and CPU :-)

I never tried rendering skyvase.pov before. Here are my results:

1024x768 AA 0.3
Windows (render priority HIGH)
540 s total

Not so good eh? No point me mentioning the spec of my clockwork,
steam-driven PC....

Pentium 166? Perhaps 200? It's really not about your speed, it's about your
patience!

Yeah, P200 MMX. I find that it's the design of a scene that takes the time..
tweaking media parameters etc. I don't mind so much waiting for a final
render.

And your patience ran out? :-)
