I was told that my link wasn’t working; here’s the pertinent information:
Depth of field is sampled when antialiasing samples are taken, so
the way to achieve a smoother depth of field bokeh effect when doing
batch ray tracing for movie rendering is to crank up the antialiasing
samples significantly, e.g.:
render aasamples TachyonLOptiXInternal 256
render aasamples TachyonInternal 256

When rendering with the new GPU accelerated TachyonOptiX in interactive mode, ambient occlusion (AO) has ample time to sample lighting to produce a clear, crisp image.
However when comparing the PPM file from the interactive render to a PPM file generated from the moviemaker TCL plugin (also using TachyonOptiX) the PPM file looks like the AO is not done sampling yet and looks rather coarse.
From this I have two questions:
1. How can I increase the rendering time for TachyonOptiX using the moviemaker TCL script to allow for AO sampling to finish?
2. How can I set --aasamples for the TachyonOptiX render? --aasamples seems to not work as an excepted flag.
