Polling rate of 8000 Hz in Fara Razer Viper

The gaming mouse often sends data to computers to locate the mouse every 1000 times every second, while the Viper 8K Hz mouse comes at a faster rate of transmitting data up to 8000 times per second.

The Viper 8K Hz mouse also comes with a faster response and a lower delay rate compared to the competition’s distinctive 1000 Hz fuses, as the latter often comes with a minimum delay of 1 millisecond, so it takes less than 1 millisecond to send data.

While the Razer mouse came at a lower rate of 0.125 milliseconds, and it is planned to support the increased polling rate for users in games with better efficiency and performance, in particular with correction and in the synchronization of correction and launch.

The Viper 8K Hz mouse combines a sensor, a fast switching feature and also the polling rate that meets to provide the highest efficiency in games, and the click rate comes with faster performance and supports smooth use in games, so the player will not face jumps in games, as the mouse works to move smoothly.

The new rate of the mouse Viper 8K Hz corresponds to the height of the modern screens in the frame rate, where the effect of the polling rate of 8000 Hz appears, clearly when testing the mouse with a distinctive screen with a refresh rate of 300 Hz, and the gaming monitors Alienware AW2521H and Asus ROG Swift PG259QN at a rate 360 Hz update. The Razer mouse is among the versions distinguished for its fast response, amazing tracking capabilities, and low latency.
