Well, Tomb Raider is the next multiplatform game to enter the THUNDERDOME(tm) and information is trickling out as we near release. We're a week away so no crazy analysis yet but this is already out there:

On average:
PlayStation 4 = 60 fps
Xbox One = 30 fps
Yes, the PlayStation 4 build is, on average, twice the framerate of the Xbox One build. Both builds are rendering at native 1080p resolution, and generally look the same in graphical effects (though some minor differences may apply). Performance is a different matter. Both feature unlocked framerates, meaning framerate fluctuates between higher and lower values. The Xbox One build can technically reach around 45 fps, though this performance is generally only achieved during the most empty, simplest environments. For most of your play, and during action scenes, the Xbox One build will sit on around 30 fps. On the other hand, the PlayStation 4 build will attempt to hit 60 fps as often as possible, and does a pretty good job of doing so, but does have slight dips under 60 fps during certain scenarios.
So there it is. Both 1080p. PlayStation 4 = ~60fps average. Xbox One = ~30fps average. Take with a grain of salt if you’d like, but we’ve confirmed it on our end, and confirmation for the rest of the world is only a week away.
Actual gameplay with the producer here as well - it looks pretty good. 50:00 mark for PS4 frame rate confirmation. No mention of Xbone framerate though.

EDIT: 59:30 mark he also talks about the team specifically going after 1080p gameplay and 30fps as the absolute minimum.
