Nvidia releases its game ready driver version 461.40 for The Medium, which is set to release at the end of the month on January 28, 2021. This driver release also comes with over a dozen fixes, including one for Assassin’s Creed Valhalla, where the game may crash after playing for an extended period of time.
What’s New in Version 461.40 WHQL
GeForce Game Ready Driver
Game Ready Drivers provide the best possible gaming experience for all major new releases. Prior to a new title launching, our driver team is working up until the last minute to ensure every performance tweak and bug fix is included for the best gameplay on day-1.
Game Ready for The Medium
This new Game Ready Driver provides support for The Medium, a new adventure-horror game that features ray tracing and our performance-accelerating NVIDIA DLSS technology.
Includes support for GeForce RTX 30 Series laptops (RTX 3080, RTX 3070, RTX 3060).
Behavior Change in NvEncCreateBitstreamBuffer API of Video Codec SDK
In the NVIDIA driver, Release 415 and later, the behavior of the Video Codec SDK API (NvEncCreateBitstreamBuffer) has been changed to return NV_ENC_ERR_UNIMPLEMENTED instead of NV_ENC_SUCCESS when the encoder instance is configured to run in the motion estimation-only mode. As an indirect consequence of this change, the AppEncME sample application from the Video Codec SDK prior to SDK version 8.2.16 will crash due to a bug in the NvEncoder class.
The latest version of the SDK fixes this bug that affects the AppEncME sample application. NVIDIA recommends downloading the latest version from https://developer.nvidia.com/nvidia-video-codec-sdk.

Open Issues in Version 461.40 WHQL
As with every released driver, version 461.40 WHQL of the Release 460 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.
Windows 10 Issues
- [World of Warcraft: Shadowlands]: Random flicker may occur in certain locations in the game 
- [Supreme Commander/Supreme Commander 2]: The games experience low FPS. 
- Wallpaper Engine app may crash on startup or upon resume from sleep. 
- [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. 
- [G-SYNC][NVIDIA Ampere/Turing GPU architecture]: GPU power consumption may increase in idle mode on systems using certain higher refresh-rate G-SYNC monitors. 
- [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. 
- [G-Sync][Vulkan Apps]: Performance drop occurs when using G-SYNC and switching from full-screen mode to windowed mode using the in-game settings. –To workaround, either launch the game in windowed mode directly or disable G-SYNC.
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.
