It can be seen that there are three types of return rates: 125, 500 and 1000Hz. The higher the rate, the more accurate the cursor positioning, but at the same time, the requirements for computer performance are also higher. In terms of DPI, there are four options: 450, 900, 1800, and 3500dpi, but it’s a pity that you can’t set the DPI at will. Different Profiles can save different settings. For example, Profile1 is set for normal use, and Profile2 is set for playing CS. Then press the Profile button at the bottom to switch between them.
