After watching both versions in action (multiplayer) the XB1 version has a shit load of jaggies everywhere. I think the DF comparisons are pointless.
Wait till you see proper high quality 1080p footage from site like Gamersyde.
Quality of 1600x900 same as 1080p can't be shown with crappy youtube player that has worse quality @ 1080p than native 720p and from IGN video which looked good but still had terrible compression artifacts.
Unfortunetelyy Blim Blim said already he doesn't have PS4 nor Xbone right now.
