This looks much worse than Crysis. But then again, console vs pc. what can one expect.
Im guessing going from jungle to city also has a big impact. Harder to make an openworld city than openworld jungle island look good.
It is the reverse. It is far harder to make a believable, interactible/dynamic, good looking jungle than city. Been there done maps, citys are by far easier to get pretty while still having lots of spare resources. The taller and denser the city buildings are the better for perfomance vs visuals.
Where talking about going upwards 2x or more in perfomance gains while having same or better IQ. You save so much by not having to do 3D water rendering, water reflections, tons of vegetation moving forcing shadows to be updated at any distance, very limited occlusion culling and more expensive terrain geometry to model all bumps etc et etc.
