Problems in FPS after a while playing
 

During the game after a while the FPS drops to 14 and does not rise again, tenhu to land and then restart the game there back to normal, someone already had this problem?, Using the GPU is very low right now, I use a GTX 560 IT.

Is the video card, or a problem in the game?

Same graphic, same problem.

Game runs fine (50-30 fps) but after 20 m of continous play, start suttering all the time. Frames goes up and down every second, if you look at gpu work at afterburner, it looks like close peaks when before it was almost 100 full time. I will try new drivers, Ill tell.

I5 2500k, nvidia560ti 9.18.13.1422

have you deleted the cache folder?

sounds to me like a over heating problem
