A fast, easy to use, free, and community supported 2D game engine
My application runs at 30 FPS with no issue with most devices:
- 4G / 3GS / 3rd gen iPod / iPad with 4.1 / 3.2
- 1st gen iPhone on 3.1.3
But on 3G running 4.1, the framerate drops at random times from 30 fps to 15 or 7... The game can run fine for a minute and then suddenly it chokes...
Tried using instruments to see if there was any clue, but I couldn't find anything. Did anyone experience the same thing? Any suggestions on what to look for?
Thanks!
Usually intermittent performance drops occur when you're using too much memory.
An app on the 3G has about 20MB RAM to play with, though even that can sometimes be problematic with the newer iOS depending on how long the phone's been running. Once you go over a magical threshold, the OS starts rearranging blocks of memory, slowing everything way down.
Have you tried the 3G with 3.X? I believe that may be the problem, I have a 3G with 3.1.2 I can test for you if you like, in exchange I would be interested in testing my game on the 3G with 4.1 as I don't really like to upgrade and I'm afraid I may have the same problem.
The problem is the new iOS4 on old devices like iPhone 3G, do a bit of research:

Anyway, optimize your game, for what you said, it fails after a while, so it could be your game leaking and running out on memory.
