Wow.
I wonder how fast Chaoscope will run on a quad core machine.
Says the man who is still working with a single core AMD 3,2 GHz ;)

Hi all,
thanks to Scott, Alan and John for their input on HyperThreading.
Charles, sorry for the technical mumbo jumbo, I can get carried away
sometimes! :) What it all meant was Chaoscope will run noticeably faster
on multi core processors, like Intel's Core Duo or AMD's Athlon 64 X2.
For instance the first benchmark project completes in 11 seconds
instead of 16 on my machine, and I have yet to optimize the code.
Also, given you have enough memory, subsequent renders of an attractor
will read the points from the RAM rather than iterate the equation.
Calculating the equation for each point can be a very time consuming
operation. The first render the 15th benchmark project takes 10
seconds, subsequent cached renders (providing you don't modify any
attractor parameters) only take 2, which means that if this project
was to be animated it would be rendered five times faster.
Regards,
Nicolas Desprez
