When you compare using Mac OS X and Windows, it is the movement lag of the mouse cursor that you notice. This time lag32 msecBecause of this, the Macintosh (Mac OS X) is not suitable for game play or design use, and the solution is "to switch to Windows or Linux" only.

I noticed this that I live in St. Petersburg, Russia,Moonlight Media Productions GroupEugene Zuyev, IT project manager for IT. I feel lag in mouse operation and touch pad operation in general.Mac OS X 10.4 TigerAs already bothered by the time,Snow Leopard (10.6),Lion (10.7)But it is said that it is occurring.

There are tools like ControllerMate that users change acceleration, but it can not be said to be a very useful method because it takes time for the head to get used to rugs.

By the way, since 'millisecond' is 1 / 1000th of a second, 32 milliseconds is 32 thousandths of a second.
