2. Users have reported new stuttering issues in games after installing the update, which do not appear to be related to low frame rates or network delays.
3. A suggested workaround is to disable Fullscreen Optimizations for specific games, which has resolved stuttering for some users.
4. Microsoft has not officially confirmed any performance decline linked to the update, and complaints do not seem to target specific hardware or games.
5. Users experiencing issues are encouraged to report them via the Microsoft Feedback Hub, providing detailed information about their setup and the problem.
Microsoft released a cumulative update for Windows 11 on February 10, 2026, specifically for the 24H2 and 25H2 versions (KB5077181). This update brings the OS to Build 26100.7840 for 24H2 and 26200.7840 for 25H2. While this patch has already been associated with various user-reported issues, such as strange shutdowns and networking problems, gamers are now sharing their concerns regarding stuttering issues that have appeared after the update.
User Reports of Stuttering
In a thread on Reddit discussing Windows Help, a user with Windows 11 Pro 25H2 on Build 26200.7840 mentioned encountering rhythmic stuttering in games right after installing KB5077181. They noted that this stuttering does not seem to relate to low frame rates or network delays, but rather resembles a new pattern of stuttering that only occurs in-game following the update.
Workaround for Stuttering
The same user also pointed out that turning off Windows “Fullscreen Optimizations” (FSO) for the specific game stops the stuttering, although they hadn’t needed to make that change before the update. Currently, this issue is mostly categorized as “user reports”—there’s no official Microsoft statement confirming a decline in gaming performance linked to KB5077181, and the complaints do not seem to point to a specific graphics card manufacturer, driver version, or particular game.
Suggested Actions for Users
The most reliable workaround mentioned by users in the thread is to disable Fullscreen Optimizations on a per-game basis, which has helped at least one user resolve the stuttering issue, although it might alter how overlays function (like how volume displays work in full-screen modes). If you experience the same stuttering after updating to KB5077181, Microsoft recommends submitting a report through the Microsoft Feedback Hub, providing detailed information about your build, hardware, and steps to replicate the problem. This method is often the quickest way to highlight an issue to the Windows engineering team.
Following the widely discussed issues from January’s updates, any new “gaming hiccup” from Windows 11 Patch Tuesday will certainly attract attention, even if the cause turns out to be a driver interaction, a conflict specific to certain games, or a coincidence affecting only a handful of systems.
