Hi,

I have had similar issues to you but find rendering at 50% of the final
width/height to usually be acceptable (although comparissons may show that
rendering with 50% the radiosity quality at the correct resolution will be just
as good..).

I do not normally specify much for the second pass just set:

pretrace_start 1
pretrace_end 1
error_bound = same as step 1 (although I might try your technique in future).
recursion_limit = same as step 1
always_sample off

I do not really understand the radiosity settings very well I have a rough idea
of how most of them work but tend to resort to trial and error more than
educated guessing..
