Thanks for the suggestion. I made the suggested changes (check github for the latest) but it doesn't seem to be significantly faster than the other fragment shaders (within 0.1 FPS over a 150 second video). I'm at a bit of a loss as to how to investigate the performance/behaviour of the OpenGL pipeline on the N900. How'd you come up with the cycle counts? I'm new to GLSL, so any documentation beyond the spec would be super useful to me.
