I think religion is the issue here, Susan :) Right now I'm rendering a lighting nut-case (225 spotlights), and the tests were giving me the same estimate with Premium 36rpp and Normal (counting about 30%-50% additional time for the last AA pass). Then I added Blurry Reflections on top of Soft Shadows and this increased the time a little bit, but not so much. So, why use Normal when I get almost the same RTimes increasing quality? But this is strange... :) S.
