I've the game and its running well for MP..i get about 50-55 FPS in medium ..but in SP it dropes heavily to 30 and below..please release a patch for SP bad performance it is not playable for me.

Dude I know right? I can run the mp on high nice and smooth but in sp I have to go to low/med settings. what gives? The mp maps look better than sp anyways.

In fact the SP is a slightly better than SP in graphics..but idk why the poor performance in SP?

Same here! The campaign is waaaaaaaay more laggy than the beta was.

I get frame rate drops mainly during the cutscenes, for instance at the end of the first level when the shutters open to show New York 2.0, my frame rate dropped to 22... The moment the cutscene ended my fps went right back up to 30.

i'm getting the same problem, in single player if I look around at different points while moving threw the level my fps drops from 80-90 to lowest 30-35 range and then shoots right back up once I look back. But in multiplayer I average 85-100 fps at all times with no drops or stutters

what's the deal here?

my rig is :

i7 990x
evga 690 GTX
16gb Ram
Win 7
