The Razer Viper V2 Pro.

A device’s polling rate refers to the number of times a mouse or other peripheral relays its information to your desktop. The typical polling rate for wired or wireless peripherals is around 1000 Hz, which means your desktop receives updates from your mouse once every millisecond. Not to be outdone, manufacturers like Razer have started making peripherals that offer polling rates up to 8000Hz. While maintaining a 4000Hz refresh rate over wireless is certainly impressive, it’s hard to say how much this will affect a gamer’s performance given that current high-end gaming monitors top out at 500Hz. Similar to how peripheral manufacturers have been scrambling to equip their mice with more powerful sensors, it seems that poll rate has become the new metric used to gauge the effectiveness of mice in the gaming landscape. While there is empirical data to support claims that a higher poll rate leads to lower latency with your inputs, it’s still debatable whether this makes you a better player. Razer seems to think so, and believes you’ll pay for the privilege.
