FPS Dropping Problem

[bballn45]

Ever since the version 1.1.0.4 came out, I have had enormous problems with my fps. It is a very weird thing. My fps on average is 190-200. Now in basically every location it is 20-50. I will post screenshots of what I mean on the bottom. It's not the area too, I will just be sitting still in one area and my fps is 190 and then it will just drop to 40 without even touching my keys or mouse. Is anyone else having this issue because it is occuring on every map for me now. I am playing on a mac and I have been playing for awhile now and I have never had a problem with it until 1.1.0.4. Please help.
