Yeh, I has P7 before 2012 and it was very, very stable.

P2012 SSS adds more felexibility again with skins and seems to render quicker by plugging some memory holes of previous versions.

I haven't applied any service pack as I've heard bad stories from others, but very rarely does it balk, and even more rarely crash, but it has a few times, usually when I try to do something outrageous, like 7 figures in a scene all with SSS and IDL and huge maps.

BTW, that's a lot of lights in your scene LOL. Mostly these days I just use one.
