Could you please elaborate on this? As someone who has suffered because of poor glDrawPixels and glReadPixels performance in the past but has never seen a good technical explanation for that, I'm interested in the details, if you are willing to at least sketch them. Is it really a pure hardware problem? Rumors on comp.graphics.opengl are that the vendors don't invest time optimizing that path (in the driver) because there's not much demand for it. The Radeon driver performs acceptably well (contrast with the mga driver, which is 10x slower, IIRC) but it doesn't hit the maximum speed allowable by the PCI bus. Could it be faster or the current implementation opmital for that particular hardware?
