I'm using 0.99.2-RC on iPad (Device).
I have only one big texture (2048x2048) in a CCTextureAtlas.
If I setDisplayFPS to draw FPS the game run at 50-60fps.
The weird thing now: if I don't setDisplayFPS, the frame rate drop radically, Instrument give me 15-20fps.
I'm trying ton pin point how drawing the FPS on the screen can make such a difference in the frame rate.
I checked out drawNumberOfQuads... can it be related to VBO?
I tried to disable CC_TEXTURE_ATLAS_USES_VBO, but I get around 25fps, so VBO is definitely the way to go, in my case at least.
