What's the best way to programmatically detect the iPad 2's graphics hardware? -

My app needs to run a separate code (big texture) on iPad 2. How do I find the programmatics of graphics hardware faster?

The code should be future proof (i.e. it detects fast graphics hardware on iPad 3 or any other future iOS devices).

Maybe you can go with framerate, if it gets too large, then small texture Take it, if it is above 100 fps, take big size.
