i playes metroid some more, and in the battle with the meta ridley, the framerate drops when the camera zooms out and shows samus on the plateu and several "glitches" when showing the dragon in the intro, i can't help getting the feeling that there is someting wrong, but maybe it's just that it won't get perfect with a machine for $150, although i don't see a lot of persons complaining about low framerate.
