method 3
intervals 1

Instead of increasing intervals, increase samples.
intervals 10 samples 10 give you 100 samples
intervals 1 samples 100 does the same BUT is much faster. samples 300 is still 
faster than intervals 10 samples 10.

The sampling parameter DOES affect photons sampling in media. It works 
complementary with the photons parameters.
