I've coded up a little experiment and I'd like to see how it runs on an iPad 3. At the moment I'm getting 1 or 2 frames per second on an iPad 1.
You can find the code here:
Hopefully my .gitignore was set up correctly to give you everything you need. The app just displays a static image, its the Core Animation Frames Per Second from profiling in Instruments that I'm interested in.
Any help will be appreciated.
Cheers,
Brendon
