Pshemak,

Jmol 12.0.9, just released, doesn't fix the problem with atomic orbitals.
Actually, it made it worse. Sorry about that! I forgot to test it with
radial functions that approach 0 from below at infinity. The next release
will fix that; I'll let you know when I finish it.

By the way, which version of 11.8 were you using?

I did not find any difference between 12.0 and 11.8 regarding timing, but I
did notice that setting z_eff to 1.0 for an atomic orbital:

 isosurface estrans2 cutoff 0.09 phase color darkred darkblue color
translucent atomicOrbital 2 0 0 1.0;

generates an unnecessarily VERY large grid, even for 11.8 and 11.6. In this
new version, that's limited to 40x40x40, which is fine for most work; you
can make it prettier (and slower) by adding RESOLUTION 6  or something to
that effect prior to the atomicOrbital parameter. This speeds up the
calculation immensely.

Also, contours: Yes, there are serious problems with contours in 12.0. I'm
looking into that.
