It was some time ago but I think to remember rendering time was about 3 
hours - with an overclocked and well cooled i7 that is.
But I might very well have used different settings for the isosurface 
and I think a recursion limit of only 8 and not 10, but I'm not sure.

Anyway this SDL function *is* slow (mostly because the recursion I 
think) and it would be much faster by implementing the mandelbulb 
function as iteration within POV-Ray itself. Should be fairly simple. In 
case you are compiling POV-Ray from source and are interested I could 
give it a try and send you a patch?
