Wow! 

So without PBO's the app works slightly better but is still pretty slow (using
glGetTexImage() and RGBA) however when I enable PBO's using RGBA the result is
blistering! I'm now getting much faster rates than Windows :D :D

If it's useful I could send another trace without the PBO optimisation.

Otherwise I'm back in the land of the living :)
