This guide describes ways to optimise OpenGL Shading Language (GLSL) code for PowerVR Rogue and Volcanic architectures. These optimisations are low-level, and therefore can be used to get the last ten percent of performance boost from the hardware. Before using these techniques, it is essential to make sure that the most optimal algorithms are being used, and that the GPU is well utilised.
