my guess is that you call SDL_Flip() and this synchs to vertical refresh
in fullscreen mode, and you have a vertical frequency of about 74 Hz.
It's a feature :)

good idea. sdl is driven 99% by Sam and the rest by volunteers like us,
so if you build a foundation I'm sure others will help you verify and
add to it
