How on earth was it possible to render such a monster model in 1 minute ? 
I have a mesh of approximately 1 million smooth triangles which takes a 
long time to render, mainly because of the long parse time (the file 
containing the triangles is approximately 150 MB). Is the parse time not 
included in the 1 minute time ? And doesn't this also require a *lot* of 
memory ? I'd love to be able to render bigger stuff than my 1 million 
triangles; they are a 'subsampled' version of the original model in order 
to get acceptable speed.
