I tried your settings out on my "Arnold" character and it used just 9 megs
for a 320 by 240 image and took only 4 1/2 minutes. Count was 200,
error_bound 0.0001 (yep, I made it that low), otherwise the same.
I noticed the "radiosity samples calculated" shown in the stats said nearly
99% and it occured to me I usually see 50% there, or around that. I
commented error_bound out and it showed just 0.45% (bad render too). Also,
the reused amount was much smaller with the smaller error_bound.
And yes, I could see the differences in your renders although it takes some
scrutiny.
It doesn't seem the pretrace is much of any matter by the time error_bound
is so low but still makes a difference (visually) when using 0.1 on up I'd
say.
The render time was a fraction faster than one using a pretrace start 0.1
pretrace end 0.01. By "fraction" I mean 5% percent or so.
