I was mostly referring to speed, apart from that it's never good if a
technique totally depends on aa (or focal_blur) to function.

Using focal blur for smoothing will not work in the focal plane, you will
always get a grainy appearance there.

BTW, did you use the default normal accuracy or a different value?
