Microsoft just rolled out its freshest Xbox One update, delivering native mouse and keyboard support across select games. Further expanding the console's feature set, its implementation brings a viable gamepad alternative, with compatibility for most USB-connected peripherals. However, despite extensive Xbox Insider testing, it appears some users are experiencing mouse issues following the public release.
We're seeing numerous reports of Fortnite Xbox One players experiencing input latency when using a mouse and keyboard; a delay between moving the mouse and a subsequent on-screen action. The issue's cause is unclear, affecting only select Xbox One players, and we're currently unable to replicate it as of publication.
Given the variety of modern mice and keyboards on the market, it comes as no surprise issues are arising in the early days. Current reports detail extensive latency in Fortnite exclusively, with both Warframe and Minecraft mostly absent of the issue, indicating something isn't playing nice with Microsoft and Epic Games' solution.
It's hard to identify a fix, but one likely culprit could be polling rates, essentially the response time of a mouse, measured in Hz. For example, a mouse with a polling rate of 500Hz will report its position to the PC or console 500 times each second. While a higher polling rate means finer control in theory, it requires both hardware and software to keep up, which can be a cause of input issues.
Depending on the polling rate used by your mouse, you may be able to increase or decrease it to alter performance and how the pointer handles in-game. Microsoft doesn't offer the functionality natively on Xbox One, meaning this option is limited to those with onboard mouse memory, by changing polling rates via a PC. Razer Synapse, Corsair iCUE, and Logitech Gaming Software are among those touting configurable polling rates for respective accessories.
Alternatively, if you have multiple mice in the home, switching it out could be a temporary fix until Microsoft addresses the issue.
