Hi,
I have every setting maxed out except chromatic aberration at 0 and no motion blur. I usually cap fps wise at refresh rate of 144hz and while in combat drop to around 130ish. Now while in Green Bluffs I still have the exact same fps except when I enter the first side area. Then my fps drops to barely over 30. The only place in the side area which has 'better' fps of around 60 is right next to the thing that lets you leave the area at the end of the dungeon.
I hope this report is of some use.

Cheers!
