Yet again, we're faced with another case of development of a game for the previous console generation holding back performance on the current generation of consoles. Development for four platforms is apparently the reason why Destiny does not run at 60fps on the Xbox One or PlayStation 4.
"It's a lot of different things," explains Jason Sussman who is the senior environment artist at Bungie. "I could get really technical, but I’d bore you to death. A lot has to do with performance. We’re cross-platform, so we had to be very delicate with all four consoles, making sure they have the same experience, that it looks as good as it possibly can on all these consoles. A lot goes into that, from geometry to textures to post effects to particles to how many players you get on the screen. We’re always balancing that out to make sure everyone gets the same experience."

Parity. Terrible, terrible parity. The sooner these cross-generation games are done being developed, the better off we'll all be.
