For low or full speed devices, that is 1000Hz. The polling rate is how often the USB host (your PC) asks for information from the device. Increase your polling rate - Increase the polling rate of your device to the maximum. That processing time can vary in duration depending on the mechanical parts used in the peripheral, the techniques used to handle click detection, and the polling rate of the device.Īs gamers, we only have a couple options when it comes to optimizing our mice and keyboards:

Mice and keyboards sense and process key presses and movements. Until you can get your hands on one of these butter-smooth displays, you can get started by measuring parts of the latency pipeline using in-game latency stats in games that have integrated NVIDIA Reflex technology, or with the rendering latency metric in the GeForce Experience performance overlay.

Using the NVIDIA Reflex Latency Analyzer integrated in G-SYNC 360Hz Esports displays coming this Fall, you can measure end-to-end system latency, peripheral latency, and PC+Display latency.

System latency breaks down into three key parts: peripheral latency, PC latency, and display latency. When optimizing for system latency, we recommend starting at end to end system latency, and digging down deeper from there.Īs a gamer, system latency impacts us in a number of ways: aiming precision, peekers advantage, and PC responsiveness. If you are new to system latency, check out our recent NVIDIA Reflex article that starts at a high level and breaks down the concepts of end to end system latency.Īs a quick refresher, here is a video that details the differences between network latency and system latency, walks through the rendering pipeline, and discusses some basic optimizations that can be done to reduce system latency. In this guide, we’ll cover how to optimize your setup using NVIDIA Reflex technologies, system changes, peripheral tweaks and more for the lowest possible system latency - the time it takes your mouse clicks to end up as pixels on screen. If you want more responsive gameplay, but don’t know how to get started, you’ve come to the right place.
