I ran these scenes with one of the new binaries provided by Chris Cason. 
These all were rendered with pvengine32-sse2.exe.

The first image uses the same global settings previously posted. Render time 
was 7h 53m before I stopped the render. The low error bound of 0.02 slowed 
it to about 7pps.

The second images uses new settings including a higher error_bound and 
additional pretrace options to reduce patchiness. These are the only 
settings that were changed:

pretrace_start 0.08
pretrace_end   0.02
error_bound 0.15

render time 54 minutes

For the last image I used these new settings to rerun the scene file using 
version 3.6. Render time was 3m 58s.

If anyone has any suggestions for how I might alter the settings to improve 
the render I would be happy to rerun this test.

Mike
