This is a new one for a console release. It seems as though Square Enix has included a resolution option for the PlayStation 4 release of Final Fantasy XIV: A Realm Reborn. DualShockers noted the display setting after today's big beta update.

The setting switches between 1080p with a chance of a reduced framerate at parts and 720p with a more stable, higher framerate.

The article revealing this at DualShockers has plenty of additional screenshots and even some comparison gifs if those tickle your fancy.
