Where does this information come from Dennis? Where is this delay happening? I doubt it's triple buffering, since the extra memory would have to be accounted for, and it makes tearing mostly impossible (as on the Mac). So you believe the Gl command queue is buffered/delayed somewhere? Doesn't that have huge implications for things like glGet, making them impossible to use without at least halving the frame rate?
