tictactoe, I believe those frame rates suggests that vsync is enabled,
limiting the rendering to the refresh rate of your screen. The same happens
here. Unfortunately, though, 3D and 2D graphics don't seem to be synced to
vblank, since I still notice tearing.

I'm using the same setup with you (Jaunty with latest updates), except that
my video card is a Intel X3100 on a Dell Inspiron 1525.
