I haven't found B+ faster than B3d (2d mode), if anything it's considerably slower in canvas mode, not talking about the new pixel writing routines(haven't tried these yet). Although speed is OK for aplications and games. Also Mark S. is doing something about this. Also most games will run in full screen mode.
But one frame a second seems ludicrous, are you sure you have turned debug off?
