I think the millions of procedural hairs are actually one of the less hard parts on the render engine compared to the GI and all that stuff. As I've learned from my recent attempts at using hair and fur in 3dsmax hair is often rendered with some kind of buffered method, rendering one procedural hair at a time. keeps memory usage rather low, which is good, and it goes TONS faster then creating polygonal geometry for all those hairs :) especially so if you create a seperate render tool for the hair passes, like something that's not good for anything other but hair... lol

The hair doesnt impress me as much within the 13 hours, what does impress me is the 4k resolution rendering with GI! That's massive. Especially if you use lots of water 'n stuff. Ever tried rendering a scene with GI and raytraced refractive objects? I did and quite frankly i wished i was back in bryce 'cuz even bryce renders refractive objects faster then that!
