Do you think it's a good idea to use more metrics than just average frame rate when testing render performance? I mean 95th percentile, minimium frame rate, etc.

I'm trying to convert a desktop OpenGL shader to OpenGL ES. The shader uses textureOffset, which isn't supported. I tried just adding the offset manually, but that doesn't work.
Does anyone know how to emulate the textureOffset function?

If you create a depth texture using glFramebufferTexture2D will that texture still be available in the next frame?
I ask, because I see artifacts in my shadow map if the shadows are only rendered once. If I render the shadows every frame there is no problem. It seems like something is corrupting my shadow texture.

Does anyone know of a fast way to tell if a matrix has non-uniform scaling?
