1000Hz is more than enough for almost all gamers. Higher rates (like 4000Hz or 8000Hz) can theoretically reduce latency further, but the real-world improvement is minimal and requires a stronger PC.

All high-end mice allow you to alter the polling rate via driver software or bespoke buttons. A few of them offer hardware one-click switching depending on specific circumstances.

Wireless high-end mice (e.g., ATTACK SHARK series) also support 1000Hz polling rates. Their lag is practically imperceptible from wired mice, meeting all esports demands.

A higher polling rate means more frequently chatting with your machine, but a bit more power consumption. That being said, the battery hit at 1000Hz is imperceptible and will not even become a concern for general usage.
