Query: You need a very fast PC!

Nearly the half of the examples in this book need a lot of cpu-power to render it. I've got some p-ii 333 mhz with 128mb ram. It has a beautiful sun, but 3mins/pic is to much. All fire Effects use (Particle)Combustion. To less explanations of the parameters. Too much is given by pre-load file.
