Nvidia says it’s aware of an issue where some games could have “lower performance” after recent Windows updates, and it’s rolling out a new display driver (version 581.94) to address it.
Nvidia confirmed that when KB5066835 (October 2025 Update) or newer (KB5068861, November 2025 Update) is installed, a bug could reduce FPS. This issue was first observed in our tests in October when the Patch Tuesday update shipped, and Nvidia has finally confirmed our reports.
KB5066835 is a Patch Tuesday release, and it is automatically applied on PCs running Windows 11 25H2 or 24H2 (these two are the same platform, so you’re affected regardless). Even if you skipped Windows 11 KB5066835 somehow, you’re still going to experience performance issues because newer releases also include those changes.
