If you spend a little time with MR you can get some great results with it for quite a small render time, for example the guitar that I did was rendering a frame in 20 mins, Once you get the hang of what the settings do you can get going pretty fast.


The more photons that you add to the scene the longer the render time, I doubt that it would get to the render times of Maxwell though.

End of the day it does take a bit of fiddeling to get the render looking nice, but its worth it.
