Adaptive DMC - Lowersubdivs = burned out

[Numse]

Hi,

When I lower my Adaptive DMC max subdivs from 20 to 4 the whole image just burns. Why is that?

Maybe becouse subpixel mapping is on, and when you lower AA subdivision - less AA rays override the correct calculated gi rays. I mean, if you keep subpixel mapping off and rise AA subdivisions you will get the same correct brightness (that may look burn out comparing with clamped result) but when you switch on subpixel mapping the value of AA subdivisions matter as they override pixels with clamped result.
Sorry for my english.
