What is zero-latency-mouse-mapper?

This repository presents a tool called PrecisionSync, described as a mouse input lag reducer for Windows gaming PCs. According to the README, it adjusts Windows system settings such as USB polling rate, which is how often the mouse reports its position to the computer, along with CPU scheduling and graphics settings, aiming to shorten the delay between moving the mouse and seeing the result on screen. The README describes a configuration profile system for different games, a command line interface, a dashboard showing real time latency measurements, and optional AI integration that lets a user describe their hardware in plain language to get suggested settings. It lists Windows 10 and 11 as the only supported systems and states the tool works at the kernel level, meaning it operates deep inside the operating system rather than as a normal application. This repository fits a pattern seen across other repositories reviewed in this batch. It was created and pushed on the same day in May 2026, contains no actual source code, and its only download link points to an external GitHub Pages site rather than a real release page. The README explicitly tells users to add the software as an antivirus exception, which is a common tactic used to get harmful software installed without being blocked by normal security warnings. While legitimate mouse latency tools do exist for Windows, the combination of a same day repository, no visible code, a kernel level access claim, and an antivirus exception request is a strong warning sign. Downloading and running this software carries a real risk of installing something that damages your system or steals personal data rather than improving mouse response time.
