Q9FN Bros. It seems no one knows what firmware 1251 did.
I, too, do not know what it did.
But I, for one, wonder if others do. I was watching a QA video (shhh, just wait. I know 87% of you just stopped reading), and he was trying to bash the firmware like always. But he did mention he noticed more shadow detail.
Granted, this was on his Q8FN - but perhaps this means that the algorithm is a bit less aggressive? Anyone want to take a stab at looking at scenes that were hilariously crushed before? I havent had mine long enough to really be familiar with what to expect from the detailing.
