View Full Version : fast glReadPixels
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?

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).
