Quote - Hm, something else seems to have changed too. It used to be that increasing IDL bounces greatly increased light spread, so that you didn't need extra intensity to lighten up dark areas. My initial testing indicates that may no longer be the case.

Anyone else checking in this area? Maybe I don't have a complex enough scene to make a different yet, I dunno....

It must be that having the IDL intensity to 1 is just as BB stated. It is way to much and adding bounces just compounded the problem, increasing the brightness to much with each bounce.

With the intensity turned down, the light still bounces, but it doesn't drastically increase the brightness with each bounce.

I real world lighting each bounce should only increase the brightness by a small amount off of most surfaces anyway.
