Lags on the high resolution (retina)

Unity Engine
1

Hello. Sorry for my English. I have completed the simple 2D mobile game. The problem is that at high resolution (eg 2048 × 1536) proposes a game (30 fps). On the other resolutions (eg 1440x900) all good.

If I turn off the UI then game runs smoothly

The profiler can be seen that “Gfx.WaitForPresent” loads of about 80%

I really hope for your help because I do not know what to do.

Anything? I’m trying to do for about 4 months. I think to throw this thing. :frowning:
