And then the question becomes, just how many textures do you need at any one time and can you load them on demand? What are their dimensions? I recall that powers of two were usually faster to load, though that may also depend on the OpenGL implementation and drivers.

I've also heard about keeping a context somewhere where it won't get destroyed, somewhat like this thread: opengles view switching problem
