ohhhh sry lol i see to many questions about games, anyways i once had the same problem and its easily fixable, what u have to do is go into the nvidia options and theres something about colour correction and u have to set it to all, im not certain where it is or what its called but if u can find anything like that then that should do it, i would tell u exactly where it is but i cant use my comp at the moment so im stuck with an old ati card
