Any of you using the Pro, the system update to 4.5 added a Boost Mode option in System. This unlocks the full system power of both CPU and GPU. I just did some running around areas that were notibly sketchy, like Caustic Caverns and Washburn Refinery. CC was much better. I spend too much time farming varkids down there and usually when you open the door and run to the hut you can see fps droppping, but with boost mode on this seems to have gone and plays much smoother around that area. Washburn on the whole is much better, but still a couple of places where it dropped.
So good news really for Pro owners, another performance boost. Cha-ching!!
