I'm just about at my wits end today. I had a game started that I was hoping to just use UIKit for all the graphics. Yes, it's hackish but it worked until I got about 95% of the stuff in the game.

Now I've switch over to OpenGL but I cannot for the life of me figure out why it's running at about 46-47 fps instead of 60. Right now I'm drawing three quads (as three triangle strips). All three are textured and sampled from one 512x512 sprite sheet (so I never switch textures). This isn't my entire game, so I'm worried that it's already at 46-47 fps when it really should be able to tear into this and get 60fps.

I think I need to be using Instruments for this but I can't figure out what to look for in terms of bottle neck. I used the OpenGL template (which is how I found out the frame rate), but I can't figure out what to look at to determine the bottleneck.

Any ideas or help?
