Take the 2-minute tour ×  I'm interested in some performance
tweaks for a relatively simple OpenGL ES based 2D iPhone game.
What performance tweaks have you found? The performance of the
game is pretty good on most devices (3G, 2nd gen touch, and
iPhone 4)... But I still want to give the user the best
experience possible.  p.s. I'm still using OpenGL ES 1.1

down vote accepted  Some low-level things that might help:    •
Turn "thumb mode" off. This is especially important if you have
lots of floating-point operations, like most games do.   • Use
CADisplayLink to drive your loop   • If you're using a lot of
floating point math, consider using the vector floating point
processor or the new intrinsics library.  And of course, profile
your game with Instruments and Shark to narrow down where the
performance bottlenecks are.  Check out my presentation from
last year's GDC Austin for more details on iPhone performance
optimizations.  share|improve this a
