The Darkness 2 Cheats
from what i've read and heard..not all games support SLI/Crossfire and if u have it on then it cud be the reason. try turning it off and then see.
also u cud try changing the resolution. see if that helps. i hope u'll excuse me from stating the obvious about updated sound and gfx drivers.
