Man, it's almost as if you guys have never played Battlefield. I've always thought huge maps and draw distance has been a mainstay of the series since BF2. And you need good resolution to really experience it.
Okay, yeah, all that's been pointed out is stairstep powerlines and jaggy scaffolding. But you know what, you really will notice it a lot more when it's an enemy on top of a building, or down the street. It matters a lot, and a lot more when the image is actually moving. There's a lot of diminishing returns at play here in terms of money:res, and obviously the PS4 seems to be pretty high up there in those terms.
But I think 1600x900 is too low, and 1280x720 is just unplayable garbage. I think DICE should have delayed it a month (if it was a matter of fine tuning performance), or just dropping the quality a little and giving us at least 1080P on the PS4. But I don't know, maybe that would have been not feasible.
720P is just a mess. Yuck.
