What's the fastest way to read pixels from the frame/depth buffers? what's the best data format to use, and pixel storage parameters?

Hi !

There is none... glReadPixels is always slow, but keeping it simple is usual the best thing, if you are using a format as similair as possible to the actual video resolution you should have something to start with. (RGB or RGBA as bytes).
