In Final Fantasy XV, pre-rendered and real-time graphics do look different. Not that different, apparently.
Recent Japanese magazine scans show a pre-render and real-time comparison for FFXV character Cidney, the first female Cid.
While she's not a playable character, Cidney appears as an in-game mechanic.
Of course, these are still images, and thus, should be viewed with slight suspicion. Seeing the character in motion would show an even wider rift between them.
But as Square Enix showed off last year, the game also seems to look lovely in real time. If true in the final game, the days of a wide pre-render and real-time gap are numbered.
