I guess that's a very valid point - though owning the game on PS4 perhaps gave me a sense of messure on what is lost and what isnt when comparing the real on-screen experience to the HD YT footage. It's not a perfect tepresentation for sure. I guess my observations are that BF4 has a lot of faked foliage. It comes across, on numerous occasions, of a game with generally flat surface (compared to that other game), but makes up for it by having a very robust and realistic lighting model and extremely detailed textures. It's a nice mix and as i've mentioned before - looking at it from a purely untrained POV, i think it's simply gorgeous.
If I am however comparing it from a more tech angle and put artistic direction aside, that other game is a LOT more complex. The geometry is a lot higher as evident by the complex terrain and the open nature and lighting is just showing off to the point it's just on a IMO different level. IMHO, it's hard to judge this through YT videos, but was quickly evident after playing for the first hour and comparing.
In other words: BF4 might be the prettiest, but it's not close to as demanding what is being rendered. Different approaches i guess, with different design goals, different art-direction which IMO is fine.
As a personal preference thing; BF4 wins for me since I value the framerate and the realistic style more - and when i want to show off some great next gen graphics to a non-tech person, BF4 would be the game I'd show. If i want to gloss and marvel at the complexity of what is rendered, I would be showing that other game instead.
