[Bf-committers] Does Cycles waste half it's possible performance or am i wrong?

[Tobias Oelgarte]

Hello,

I'm curios why i never see fireflies in cycles that affect more then one 
pixel. I have chosen to speak about fireflies, because they are the most 
unique sample that one could observe. It doesn't matter if set the 
gaussian filter to 1.5 or 10. The fireflies, no matter how strong they 
are, only cover one pixel. I see no distribution to other pixels of the 
film. If I'm not mistaken then i should see this sample contributing to 
at least four pixels (except the sample is perfectly centred and 
gaussian is 1.0).

So I'm wondering why this samples do not contribute to neighbour pixels. 
If they would, then it would expect a significant noise reduction. 
(about half the samples for same result)
