hey, im running Crysis 2 on EXTREME on 1280x1024 (yes im getting a new screen) which is my max screen resolution. Whenever i reload the L-TAG i get random FPS drop and when the animation is over it stops.
My gpu is: Radeon HD 6870 1GB

sounds weird. I have a HD5850 and I notice no drops at all.

do you have the newest Catalyst drivers?

I have exactly same issue.. and it's even worse while im cloaked - fps goes so low that its better just to be in corner and look down or smth

otherwise it just lags the f out of machine and then buttons might not work for some seconds
