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).
