hi, I am doing a game, starting from a prototype, which seemed ok, so I have started to add things and tweaks. Now from an unknown reason to me it looks slower, the accelometer or buttons don't respond how they should, sometimes it freezes for a micromoment, basically it does things it never did. I am not looking for ultimate answer, cuz this might cause anything as the code has more than 1500 lines, but some kind of tips and trick what to look for or maybe somebody is experiencing the same problem. ie I know that NSLog() slower it down significantly so I watch out for this. I dont know, it might be some bad memory management as the game is getting bigger... Thanks for ANY help.
