hahahha Fran on images with slow anti-aliasing you can set the render to "fine art" or "premium" mode at 4 rays per pixel. In these modes, bryce oversamples each pixel, so there is actually no final anti-aliasing pass, it's included in the normal passes. This can really help when you have a lot of bump maps and usually gives better quality than with regular AA in the first place. I find that for regular setting images the clock is way off because anti-aliasing takes a lot longer or shorter depending on the scene. On premium settings, since there is no AA pass, the clock tends to be much more accurate.
