Hey guys, I'm working on my second iPhone app, but the first game. I'm running into performance problems (framerate) using OpenGL on the simulator with my game, and the performance seems to be a function of the amount of geometry. I've done everything in the programming guide regarding efficiency except lumping all of my objects into one draw call and nothing has helped. I've heard the iPhone and the simulator have varying performance, but I was wondering if it's possible that it will perform better when I pay the $99 and put it on my phone? I've played games with what seems like significantly more complex geometry. I'm not using texturing, have one directional light, and have almost exactly 2400 polys in the scene by my count, ~1/5 of which are visible at a time. getting like 2 fps. Thanks for the help!
