Windows 11 mouse stutter in games: after KB5127648 or the November update, is your camera smooth again, or was it your polling rate, dock or driver?

Microsoft says its October 13, 2026 update KB5127648 fixes an issue that could make mouse input stutter in some games on Windows 11, but it names no game and no cause. If you had a jerky camera in a PC game, did the update fix it, or was the culprit somewhere else?

It presents the November 2026 update (KB5132061), which includes the October fixes; it does not specifically cover the mouse issue: https://www.youtube.com/watch?v=viCna57sYW0

What Microsoft's notes say: KB5127648 (builds 26100.9711, 26200.9711, 26300.9711) "fixes an issue that could cause mouse input to stutter in some games", and the November 10 update KB5132061 (builds x.9974) includes it. Windows 11 24H2 Home and Pro received their last update in October 2026.

Our questions:

1. Which game(s) stuttered for you, and since when (a specific Windows update, a new mouse, a new GPU)?
2. Check winver: which build are you on now, and is the stutter gone since the October or November update?
3. If it still stutters: did lowering the polling rate (8,000 or 4,000 Hz down to 1,000 Hz), plugging the mouse straight into the PC instead of a dock/hub/monitor, or a clean GPU driver install fix it?
4. Wired or wireless mouse, which brand and software (G Hub, Synapse, other)? Does G-SYNC/FreeSync change anything?
5. Still on 24H2 Home or Pro: did you install KB5127648 before moving to 25H2/26H2?
