It is pretty bad, but I just got to a conclusion that it is worse than it seems.
Thing is, I bought BF3, and I started playing. Got 20FPS on medium. Taking everything to low, turning off shadows, AA and anitosropic, turning off all background proccesses, turned the resolution down to 1280x800(from 1920x1200). Getting 45 FPS on METRO which is the least demanding map on this game as I understood, AND the game looks like shit. Low FPS + shitty graphics, come on.. My PC isn't that bad, there must be something I'm missing... any clues?
