You are right, the stats report about 1-2% of new samples. But almost
in all my recent scenes this leads to invisible artifacts. On the
difference image you have to raise brightness and contrast to the
maximum to see them. But curiously, the artifacts do not seem to
visually have any relation with the tiles... they seem a global thing.
In any case, I suppose this happens also when I distribute manually a
rendering over my machines. And as I always use the two-pass radiosity
method, the only difference for me when using XRS is that I need much
less effort and time to obtain the same result.
