Must have for any graphics engineer

This app is a must have for any graphics engineer using OpenGL. Quick access to extension specs, easily accessible hardware limits.

Minor Problems

This is a great app for benchmarking the iPad's OpenGL capabilities. My only problem is that after the last update, I have not been able to see the framerate after doing a benchmark. Also, no new benchmarks seem to have been added to the iPad version.

Amazing app

Nice documentation, and neat benchmark feature. I look forward to using this app once I start programming in OpenGLES!
