[Radiance-general] Radiance - Mac Performance

[Lars Grobe]

Hi! 
 
First, I have just ordered my 12" Powerbook ;-) Second: my 
experience is that rendering speed depends on memory (nothing 
is as stupid as a rendering process on a fast machine waiting 
for data from the swap!!!), cpu frequency and - that is really 
important - the optimization of the compiler you are using! 
 
I couldn't find great imporvements with radiance on 64bit so far. 
 
However, one thing to mention - a stable 800MHz machine doing three 
renderings over night is much more performant than a 3200MHz 
machine which crashes three timer per rendering ;-) In my personal 
experience, the "rendering speed" is not the critical point any more 
in our days, much more is the stability of machines. I put 90% into 
the preparation of a rendering, and only 10% in the actual render 
process ;-) 
 
So, these were some thoughts of someone who prefers to render his 
pics on an old AMD K6-2 300 ;-) CU Lars.
