Ultrapolling increases the amount of times the firmware on the mouse reports its tracking data to the computer to 1ms (or 1000hz). This reduces the interval between each transmission of movement calculations, giving the cursor on -screen a smoother and more precise feel and increased responsiveness. (also see Polling Rate)

This means that once Ultrapolling is set, the mouse can be used on other computers and the computer will always receive 1000 reports every second.

Increased polling rate translates to smoother and more true to movement tracking. One second of mouse movement is communicated to the computer through 1000 different reports of location and tracking data. If you took one second to draw a circle, traditional polling would have that circle made up of 125 position points while a Razer mouse with Ultrapolling would draw that same circle with 1000 points producing a smoother more accurate picture. This translates directly to in game accuracy and movement.

Once the driver is used to switch the firmware to ultrapolling, the mouse will permanently poll at 1000hz, regardless if drivers are installed on the computer or not. This means that once ultrapolling is set, the mouse can be used on other computers and the computer will always receive 1000 reports every second. Ultrapolling increases accuracy and quickens response time giving increasing the effectiveness of the mouse in game. Any game that requires quick precise moments will benefit from Ultrapolling.
