You should consider using page flipping instead of double-buffering. As a
matter of fact, it's almost the same as double buffering with one except:
you do your rendering right into videomemory, so no data moving is needed.
You just change visible area on the screen from one page to another and so
on - this is obviously faster than double buffering (assuming that videocard
has enough memory to hold more than 1 page).
