I hadn't played BF3 in a long time and as you know, I play on a PC and have most of the goodness turned up full. I'm telling you there isn't a noticeably massive difference in meaningful graphics quality. Don't forget (as I recall) you didn't initially install the extra textures on your Xbox.
But BF4 does look look very nice I agree and the lighting and level of detail is pretty breathtaking. I was surprised that BF3 had so much detail after some of the games I've been playing recently. Maybe you should view some of the BF3 'pretending to be BF4' videos on Youtube that some nobheads have put up, to see for yourself?
