when you first enter the nukara prime exterior map i'll run at 50fps (19.9ms/fm) after running around the easy area and come back to teh main base i'll sit at 22fps (45ms/fm).

I've noticed this also, pop into the caves and come back out again and it goes back to the original FPS rate it was at when you beamed in,

this is still prevalent even after some tweaks that were done in the latest patch,

in my case, I dropped all the way down to 9fps, popped into the caves, came out 53fps solid, also to prove my card isn't at fault because it's a gtx580, I dropped the res to 50% render, made no diff
