Here's the problem: i'm playing the game with almost everything on ultra, except shadows, that are on medium, anisotropic filtering to 4x and i've disabled depth of field. My game have always runned smoothly, with fps varying between 40-60. But now, after i load a saved game and play for about 10 minutes there is a sudden and huge fps drop, to about 5 fps more or less. The game gets unplayable. And if i close the game and open again even the open screen is with this fps, i need to restart or log off the computer to get back to normal. Is there anyone else experiencing this?
