ok, seems to work with almost everybody, CLICK OFF full screen mode, as easy as that, its in the game options, your flickering is now fixed, now we wait it out till the game producers fix the bug. I REPEAT you dont have to change anythign in your ccc or whatever for sli, or rename files that have no need to be renamed, just take off full screen mode in the games options, have fun =D and someone from crytek should definately put this solution for the time being on top of support page so that it doesnt get burried by other peoples forums. making it harder for people to find. later

Thanks works for me, that light was driving me insane
