- Yeah, I know. But that's because you're not doing a WaitBOVP()
- after the LoadView(). LoadView() doesn't wait for vertical blanking,
- so you'll need to do that yourself (with WaitBOVP(), actually).

- I made this mistake myself once, with an anim player, and I got >60 fps
- in one case, and with PAL that's supposed to be impossible... :-)
