Nice comprehansion. The quality render values are quite too low to get real working results. It would be great, when we could see the render result comprehanded with Details 0.8, 0.9, 1.0, AA 8, 9, 10, 11. Just to see, if max render detail settings will bring the same result as 0.8/9 but you saved 4 hours for example.
Just a little notice, thanks for your work and the upcoming quality examples.
