If the pointer is moving a fraction after you move the mouse then the answer may be a trojan/virus in your system.
To test, close all applications to rule out CPU/Memory load as the cause and see if the lag still occurs by moving your mouse left and right in quick, single jerks on the desktop. If it still happens then maybe some malware has inserted a program between your mouse (and video/keyboard) driver and the processor to remotely monitor your actions. This can cause the delay.
I wouldn't trust any currently installed AV software since it may be compromised.

Turn the mouse off by flipping the on/off slider on the bottom of the mouse to the off position. Replace the batteries, turn the on/off slider to the on position and set it down in front of you iMac.
