Alright, so did a little test. No ENB at all. Whiterun gate looking at market without JK - 47 fps. Whiterun gate looking at market with JK - 25 fps. (this is about 20 frames as stated but puts me into the 20s as I stated before) Whiterun Dragonsreach looking over the city no JK - 52 fps. Whiterun Dragonsreach looking over the city with JK - 25 fps. (ouch! 27 frames down.) Mesh differences perhaps. In any case, I can visibly see it chug when I walk through towns and it bugs me too much to use. It does look very nice but think it goes a little overboard in places which might cause the performance hit.
