  Why AA0.0?
  You have big areas of very low contrast, so using an antialiasing threshold
>0.0 would have probably speeded up the rendering considerably.

  If you want high-quality antialiasing you should use the antialiasing
method 2. It's slower than method 1 (the default) but gives a better result.

  So something like: +a0.01 +am2

  Of course the best antialiasing is got with +a0 +am2, but that's really
slow. (In some special scenes this is the ONLY setting that gives a
decent image quality; for example I posted some time ago a scene with
a landscape made of spheres viewed right from above, and the only way
of getting it look right was using +a0 +am2.)
