So far I'm moderately enjoying it. The visuals for PC are quite beautiful, however I am disappointed that TressFX takes such a massive hit on framerate. As others have said, it can look pretty wonky at times, but it can also look amazing. Game runs smooth as butter maxed without it on a 670, but I think it's worth the hit to leave TressFX on.
The 'PC Features' article sold me on this, got it for $24 on GMG with discount and credit a couple days ago.
I wonder if they will release a patch or something for it, or if it's just that demanding.
