I've connected both a magic mouse and a Logitech mx518 and both dont have as precise of tracking as they do on my HP Envy PC. Is this a common issue with OS X, or is there something wrong with my MacBook Pro? I just got the Mac and it's my first one, so this is new to me. I couldn't imagine OS X being poor in this regard. When I say not as precise, I mean that the actual pointer when moving is a bit "jagged". On my PC it's smooth and accurate, on OS X its a bit jump. Even when I adjust the tracking down it still does not work as good as I'm used to.
