Razer DEATHADDER ESSENTIAL Master Manual page 17

Performance
The Performance subtab allows you to modify the sensitivity, acceleration, and polling rate.
Sensitivity
Sensitivity refers to the distance the cursor will travel based on how far the mouse moved. The higher
the DPI, the farther the cursor will travel given the same distance of mouse movement.
Polling Rate
The higher the polling rate, the more often the computer receives information about the status of
your mouse, thus increasing the mouse pointer's reaction time. You can switch between 125Hz (8ms),
500Hz (2ms) and 1000Hz (1ms) by selecting your desired polling rate on the dropdown menu.
Mouse Properties
From here, you can access the Windows Mouse Properties where you modify operating system
settings that can directly affect your Razer DeathAdder Essential.
