The Logitech G PRO HERO Gaming Mouse originally had a 16k sensor with a maximum CPI of 16000. Logitech has since released a firmware update (version 128.2.7) to upgrade the sensor, increasing the maximum sensitivity to 25600. The sensitivity is adjustable through G HUB, where you can also adjust the polling rate. You can set the polling rate to 125Hz, 250Hz, 500Hz, or 1000Hz.
