I tried it, and the old version is MUCH better. I had more control, and the images were more realistic. Now they still take hours to render, but are terrible.
Ignoring the artifacting, which I believe I've solved:
Old Renderer:

New Renderer:

Sorry, but the new one does NOT include the features of the advanced renderer. I'm going back to the old version.
