Major decrease in graphics quality in new Heavensward areas- unacceptable

[Pancakesandsyrup]

I dunno, in PS4, I've never found any issue such as those, everything's beautifully rendered, except those 2D tree leaves, which is I think to accomodate PS3 and low spec VGA cards.

You've never noticed them, or they aren't there? Things like low polygon hills, clipping furniture and pixelated textures aren't the result of your system- they're a result of the amount of effort that goes into constructing the game.
