I love the new wingsuit, map and the other little improvements from JC2.
I get arround 40 to 50 fps (over 60 fps sometimes) playing on medium/high which im not complaining about considering my specs of
NVIDIA GeForce GTX 750ti SC
8 GB RAM
I have heard about high end pc's not even getting 30 fps but the game has been nice to me i suppose. =D
