Is there a way to change game resolution without jailbreaking?

[iMore Question]

I've playing a game called [redacted] in my samsung galaxy s4 before. Then I bought this iphone 6s plus just a week ago from now. I would say that even though this phone is much latest, the resolution on my old phone is much better.

Not unless the game itself has a setting for it.
