Just wondering because I tried IB2 on my 5S for the first time and it looked a lot worse than I thought it would... Plus there was all those issues with games not recognizing the iPad Air so I wasn't sure if this was the same kinda issue. Idk maybe I'm just spoiled by IB3
I can't vouch for the *maximum* setting (i.e., as graphically intense as when the game runs properly on an iPad Air), but it certainly looks smashingly stunning on my 5S. The differences between IB2 and IB3 on my device lean more towards subtle than overwhelming, which might give an indication as to just how good IB2 looks.
i played ib2 on both my ipad 2 and ipad air, and graphically they are identical, just with a better resolution due to retina display on the air
IB2 looks absolutely fantastic on my iPad mini with retina display. I can't vouch for the iPhone 5S or iPad air, but since they all have near-identical hardwear I assume it's all the same.
