Hello Everyone!
I’m having performance issues with an itouch 4, i investigated in-depth the scene and it seems that if a texture is rendered as a background and is sized as large as the screen, it consumes a lot of rendering time. And drops the framerate drastically. The input and the animations of the character seems to be less smooth (cause the lower framerate).

I’m not having this problem in a Iphone 2g and suposedly, the hardware of the itouch 4 is better than de iphone 2g. There is any hardware problem with this? Anyone is having the same troubles?
Thank you in anticipation, any suggestions would be very helpful.

No there is no hardware problem, but the itouch4 has 4x the pixels to render so it can end on being slower.
even more so if you use shaders that would not be used on iphone 2g or if you happen to use transparent / blending shaders which hit the fillrate where the 4th gen is relatively seen weaker than the pre 3GS hardware

a texture as background should not ne be a problem on 4g, but as dreamora said , the kind of shader you use and most of all if you have several object overlaying each other with big chunk of transparency, that will be certainly a major issue

Solved! Thanks folks! :smile:
