Optimizing for Performance
When we run this example on a beefy second-generation device like a Droid or a Nexus One, everything will run smooth as silk. If we run it on a Hero, everything will start to stutter and look pretty unpleasant. But hey, didn't we say that OpenGL ES was the silver bullet for fast graphics rendering? Well, it is, but only if we do things the way OpenGL ES wants us to do them.
Measuring Frame Rate
BobTest provides a perfect example to start with some optimizations. Before we can do that though, we need a way to assess performance. Manual visual inspection (“doh, it looks like it stutters a little”) is not precise enough. A better way to measure how fast our program performs is to count the number of frames we render per ...
