Nvidia has acknowledged that recent security updates have caused gaming performance challenges for users on Windows 11 versions 24H2 and 25H2. To address these issues, Nvidia released the GeForce Hotfix Display Driver version 581.94. This hotfix driver is a beta version and has not undergone the standard quality assurance procedures, allowing for quicker deployment. Users may experience diminished performance in certain games after installing the Windows 11 October 2025 update, specifically KB5066835. The hotfix drivers are optional and have been expedited to provide timely solutions. Users can access the driver for both Windows 10 x64 and Windows 11 x64 systems via Nvidia's Customer Care support site. Additionally, Microsoft has addressed various bugs in recent Windows updates, including issues with localhost HTTP connections, smart card authentication, and the Windows Recovery Environment.
