I learned a few tricks in this article which improved my frame rates 10 fps. Things like: "Use the same sampling function for minification and magnification If both the minification and magnification filters are GL_NEAREST or GL_LINEAR then there's no reason OpenGL has to compute the lambda value which determines whether to use minification or magnification sampling for each fragment. Avoiding the lambda calculation can be a good performace improvement.
