Do some people have images turned off? The sheer astonishment in some posts make it seem like they are imaging a game like the original 2D tower defense Plants Vs Zombies.
Sure it's not a visual power-house, but it's running on the very modern Frostbyte 3 engine. I too would be disappointed by the sub-native resolution, but the fact that they're prioritizing 60fps for a responsive action/shooter game is refreshing at least.
I think the astonishment comes from a brand new, next gen console not being able to push 1080p/60fps on a relatively average looking game.
