Though the PlayStation 4 has been soaking up the majority of the spotlight, the Destiny beta is also available on the PlayStation 3, and based on this side-by-side graphical comparison, the older hardware does an admirable job of keeping up.
While the PlayStation 3 game runs at a lower resolution and features less detail than its PlayStation 4 counterpart, the broad graphical strokes remain the same. Characters bear the same futuristic, decidedly Halo-esque aesthetic in both games, and actual game content appears to be the same, down to the infamous, ominpresent Peter Dinklage voiceover. Most impressively, the PlayStation 3 beta does an admirable job of providing a stable, fluid framerate, even when the screen is filled with explosive graphical effects.
Obviously the PlayStation 4 version of Destiny looks and performs better than its PlayStation 3 counterpart, but if this comparison is any indicator, the older generation of hardware offers a perfectly suitable Destiny experience.
