There appears to be a faction of hardcore PC gamers within the Microsoft Windows software engineering team—as evidenced in a developer blog post from late May. The section relating to "Reduced game stutter with high report rate mice" provided an early preview for improvements recently rolled out in a Windows 11 update (KB5028185 issued on July 11th). This week's fix "improves your computer's performance when you use a mouse that has a high report rate for gaming." Gamers running PCs on Windows 10 (or earlier) are—unfortunately—missing out on this latest and greatest feature.

Microsoft's blog stated: We know gamers hate stutter, and we're fixing issues throughout Windows so that an untimely frame-freeze won't take gamers out of their immersive experiences. Gamers love to push their systems to the limit in search of the best experiences in-game. Many also use sensitive, high DPI, high report rate mice to shave milliseconds off their response times and increase precision. At the same time, the world of gaming is more connected than ever with gamers relying on an increasing number of background apps while playing, like voice chat, streaming, apps for configuring your keyboard, mouse, or graphics card, and more. The Windows input stack was being pushed to its limits with high report rate mice and their input being delivered to not just the game, but also multiple background processes. In turn, that caused a significant amount of time processing input rather than providing as many cycles as possible for rendering the game experience."The entry continued: "We set out to reduce the amount of processing time it took to handle input requests by throttling and coalescing background raw mouse listeners and capping their message rate. Prior to these changes, we observed on a Surface Laptop Studio with a 1000 Hz mouse, a test bed of background listeners, and popular games that there was significant stutter. After the improvements, on the same setup, we now deliver a smooth, uninterrupted gaming experience and preserve the low latency, high precision input experience in games while being efficient with input for background listeners!"Several high polling rate enthusiasts have provided positive feedback on the /MouseReview subreddit, following the discovery of KB5028185's beneficial effects—well heeled owners of high-end Razer gaming mice and HyperPolling Wireless dongle claim that they are no longer experiencing stuttering and juddering issues in several fast-paced first-person shooters, when selecting polling rates of 2000, 4000 and even 8000 Hz.
