I could not agree more Asuka. Granted framerate does drop in some instances and areas and such, PS4 does not have trouble maintaining 30+framerate at all times like some seem to think.
Unless there is hard evidence of this fact and even then not all PS4's run exactly the same, just like cars both can have the same exact engine and yet one will run a little faster. My car for instance being an example of that, hehe
Graphically it does not really matter all too much to me, the game looks beautiful and am happy with how it is at this moment.
