There's something strange with the fps though, cause when I pressed L for the adaptive sampling, things movent noticebly more slower. The fps however stayed the same. (32~35).
I was predicting fps only from time taken by sampling, not including the actual rendering. The slowdown is strange, cause after pressing L the only thing that changes is that quads between sampled point's don't get filled, which theoretically could only improve performance :scratch:
