Yeah, I totally agree on the grain.
I did the last render with the realtime renderer @ 1080p. I had set the time to 24 hours What you see is the result after 24 hours of non-stop dedicated rendering on my crappy notebook

. Planning to go DP Xeon soon...
Today I reran the render, but without DOF. Still needs more time to get rid of all the grain, but this won't take 24 hours, I reckon...
