Serious? Look at the steps, look at the lights. Look how the lighting on the steps goes from blocks on the XB1 to an actual design on the PS4. This is easy stuff man. Look at the jaggies everywhere. All the XB1 has is the darker image which was added via Digital Foundry or can be found on most TV's.
Yeah, If you want to see resolution differences made really obvious look at a scene with detailed objects at a good distance. I was looking at these pics before wario posted the comparison gif, and wondering how the two could be so diffrerent. The xbox version seems pretty close to current gen. Not that the ps4 version is incredible, but at least it feels like something I haven't seen on a console before.
