Hello guys. recently i bought Civilization V on steam. Great game and man do i love it. Problem is, it seems to be rather hard on my grafic engine. Even in lowest grafic settings it's still horrible slow and lags way to much to be any good. The thing is my iMac is only a year old and that shouldn't really be a problem hardware wise. Here are my specs: ATI Radeon HD 4850 Intel Core 2 Duo - 3,06 GHz so i should totally be able to play the game. Am i the only one with the problem or do the rest of you experience lag issues. Im not sure if it is my computer or it is the ported version of Civ V that sucks? help would be nice, thanks. Sea-Monster.
