For me, the Crysis, Crysis Warhead and Crysis 2 SLI profiles still work best rather than using the default SLI XIV profile. I have strange things happen in game when I use the default one so I stay with the Crysis profiles for now. However, for me, the Crysis profiles still have one problem for my system. The in game cutscenes flicker really bad when fading from one scene to another i.e. getting on to boat to Limsa Lominsa. Its annoying but I dont see it enough for it to be that big of a problem. I have 2 480 GTX's and I hear a lot of players with this same issue are running the 400 series card in SLI.
