Kixum, your results here are beyond amazing. Either your system is very far ahead of mine (possible, since this thing is about 5 years old now), or you are doing something that I need to learn how to do :).

Could you share your scene file with me somehow? So I could run a render and compare the times I get with the same settings on the same scene?

(If you don't want to share it publicly, maybe you could e-mail it to me, I am antara.nn on Gmail)

The quality of the light in your scene is exactly what I am trying to get, but I am not getting anywhere near it within the same render time scopes. I was able to fake it though, using Ambient Occlusion only for Indirect lighting and then faking the bounce.

I will post the result when the big image renders.
