Hi there, i’m in the final of developing a game for the iPhone.
Until now, I had a iPhone 3GS and 4S to test and it runs well on both.
But today, I tried it on someone’s iPhone 4 and get like 5 FPS. It’s as slow as the 3GS and has the high resolution of the iPhone 4S and now I have a problem.
What do you think are the best way to optimize for the iPhone 4?
my game relies heavily on pixel lights in combination with very few models (only planes and spheres, but normal mapped and a lots transparent shaders). I use up to 3 lights simultaneously and it works fine on the 4S because it’s fast and the 3GS because the resolution is low.
Is there a way to force the resolution on the iPhone 4 to be the same as on the 3GS? (one quarter) this would be a quick and dirty solution… but i guess, customers won’t be happy having no retina-graphics on the iPhone 4.
Any other ideas?
What is the general way of making a game on the iPhone 4 look as good as on the iPhone 3GS even when it has to render 4x the resolution but isn’t 4 times as fast?
