It's a console title, so they have standards. I don't have the exact number but I believe it's 60FPS.

It was a point of technical pride that it was designed to run at 60 fps. Unfortunately the game was so poorly designed and coded that any time things started happening the game was incapable of running at 60 fps.

It is basically like if Windows ME team had designed it to work on 4k. It would've made things worse knowing they wasted time on putting a flower on a giant pile of turds.
