I always trow the same example.
Early gen 7 games were all 1080p, but looked gen 6.
Late gen 7 the games were all at 640p, but look far better than early gen games.
Other factors mean far more than resolution.
Anyway, the game looks gorgeous on both plataforms. If we ever had a chrono trigger remake, the perfect approach would be following DQXI look and play.
