NVIDIA driver release version 466.11 is a game-ready driver for Mortal Shell’s RTX Update and Valorant’s Reflex update. This update also includes a few minor bug fixes, including a fix for an Adobe Lightroom bug, which would sometimes show RAW files as black.
This update also fixes a known bug in Microsoft Flight Simulator when using VR while Hardware-accelerated GPU scheduling is disabled. There aren’t many bug fixes in this release to write home about, as it’s mainly a game-ready update for Valorant and Mortal Shell.
I have included the complete list of driver fixes and other changes below, or you can read more about this release directly on the NVIDIA website here.

As with every released driver, version 466.11 WHQL of the Release 465 driver has open issues and enhancement requests associated with it. This section includes lists of issues that are either not fixed or not implemented in this version. Some problems listed may not have been thoroughly investigated and, in fact, may not be NVIDIA issues. Others may have workaround solutions.
- [World of Warcraft: Shadowlands]: Random flicker may occur in certain locations in the game 
- [Batman Arkham Knight]: The game crashes when turbulence smoke is enabled. 
- [Steam VR game]: Stuttering and lagging occur upon launching a game while any GPU hardware monitoring tool is running in the background. 
- [Prepar3D]: The application crashes to desktop after launched. 
- [YouTube]: Video playback stutters while scrolling down the YouTube page. 
- [Notebook]: Some Pascal-based notebooks w/ high refresh rate displays may randomly drop to 60Hz during gameplay. 
Issues Not Caused by NVIDIA Drivers
This section lists issues that are not due to the NVIDIA driver as well as features that are not meant to be supported by the NVIDIA driver.
Cross-adapter Clone Mode
Under Windows 10, clone mode across graphics processors is handled by the Windows OS, and not by the NVIDIA driver. Consequently, there are no controls for cross-adapter clone mode in the NVIDIA Control Panel under Windows 10.
Functionality of some display controls in the NVIDIA Control Panel may be affected if cross-adapter clone mode is enabled through the Windows Control Panel. In this case, use the Windows Control Panel to adjust display settings.
Because cross-adapter clone mode is handled by the Windows 10 OS, there are no display controls in the NVIDIA Control Panel if no display is connected to the NVIDIA GPU on Optimus notebooks.
Windows 7 Considerations
Under Windows 7, the default settings are not applied when a new display is hotplugged, and there is no message balloon alert stating that a new display was detected. All display connection and detection events are handled through the Windows 7 Connecting and Configuring Displays (CCD) mechanism.
Operating System Issues
- [Windows 10 Fall Creators Update][HDTV]: 12 bpc is automatically applied even on HDTVs that support only 8 bpc, resulting in a scrambled display. To work around, open the NVIDIA Control Panel->Change Resolution page, select “Use NVIDIA color settings”, then set the Output color depth to 8 bpc.
- When upgrading from Windows 7 to Windows 8, the system fails to retrieve the installed WHQL display driver.
