I just built this PC in May. How come I can hardly run this game? I need to play on absolute lowest shadows, no multi sampling, and everything else on "standard". Even with these settings (which make the game look disgusting) I'm not breaking 25 FPS. Did I build a pile of junk? What the hell does it take to run this game at max?
