bf4 is most certainly not ran at 1080p on the ps4.
TR is one of the 2 or 3 games that runs 1080p @ 60fps on the ps4. If you look at it, its because shaders and lighting effects (huge performance pigs) are turned down or off.
Assassins creed is 900p @ 30fps.
1080p rendered video =/= 1080p in game performance.
edit: again, its not that the ps4/xbox look "bad". Its they are already hitting their glass ceilings, whereas PC's are magnitudes (almost laughably) more powerful, and in terms of 1080p gaming, nothing is even close to "pushing the envelope" at this time.
this picture should sum up the difference between pc and ps4 pretty nicely.
Note the reflections off the water on her face, the extra detail in the skin and lips, the more complex shading going on, and althought you cant see it, the hair is WAY different on the PC version. The extra detail in the clothing as well. Most of the differences right now come in those "Details".
