I have a PC with an I7-2600 and 16 gigs of RAM (though I don’t really think RAM makes a big difference in render times).
My Render settings were on automatic - final. No IDL but I did use SSS. I believe only one light was raytraced and the others were depth map shadows (I can’t check cause I am working on another scene and rendering in the BG - very cool feature).
It’s really tough to compare render times because there are so many variables. Different materials in content can be set up very differently causing much longer render times. I’m not expecting every render to go that fast.
I’ve had DS renders go this fast (and even faster) with ray tracing even several lights with ray tracing. But the SSS went really fast and looked nearly photographic. That’s what surprised me. For me to get photgraphic looking skin in DS I almost always have to use reality.
I can get Carrara renders that look realy realistic in a couple of minutes - sometimes in seconds but when you build a whole scene the times can shoot up there - especially with clouds and thousands of plants and final render settings.
This render took under 15 minutes at 1720X1920 - It was just a test while I ate lunch. But the render with IDL is going now and after 20 minutes it’s not even part way done with the first of three render passes.
