Hi All,

I'm trying to do a simple test for my embedded board to test the GPU to CPU data rate, and is it fast enough for doing computer vision or not.

So Basically, I'm doing some fragment shader, then I'm copying the screen using glreadpixels, then I'm writing the screen to a file, and watching the FPS.. Is this test enough ?
