Yeah but that needs to escalate well.If i buy $1000 machine i expect more graphical inprovments that LOD and AA.PC version should be like the teaser.

Imo they delayed the game in order to downgrade everything cause it wouldn't run on consoles.(aka "polishing")

Why wouldn't they just downgrade the console version, aka optimising?
