Yes exactly the same rad settings & run parameters.  I should explain 
that I ran the 3.6 example mostly as an afterthought.  To compare the 
two versions wasn't really the intention of the post. Mostly I was just 
posting because I'd spent so much time bringing the lighting as far as I 
had. But since radiosity was advertized as among that changes to the new 
release I thought I would try it in comparison.

I thought the main difference was the superior rendering of the 
highlighted buckle in the 3.6 example.

I am not very pleased with either outcome actually, And I am not quite 
sure where to turn next.

And in particular I have a difficult time understanding the dramatic 
difference in finish responsiveness between either of those tests and 
this one using HDR.  Obviously I have a lot to learn and running mind 
numbing numbers of tests trying to isolate the effects of contributing 
elements seems to be the only way. :)
