This is a GLES 2.0 Shader Demo which can be used to benchmark your GPU Fragment Shader Performance. It won't reflect your devices performance in real games. Some devices with a non unified shader GPU (eg. tega) perform much slower because this is the worst case scenario for them. This benchmark uses the maximum resolution of the device, so tablet devices (or the galaxy nexus for instance) doesn't perform good. This benchmark is meant to measure the raw fragment shader performance for a full screen resolution.
It's quite demanding, so it won't run on older devices.
Makes heavy use of the fragment shader.

Check out the Live Wallpaper Version of this Benchmark Monjori Live Wallpaper which also runs, thanks to reduced resolution, on slower devices.
