I very seldom see my fps drop below 45 maybe even 40. I have seen a drop to 30 (lowest) for a split second but it was only in cut scene or cinematic. DOn't know why, but that's when most of the drops happen.
Also I've notice some strange interlacing (may not be the right word). Where it looks like the image was printed by a dot matrix printer?
I can't deal with it dipping below 50 it's very noticeable for me.
