NVIDIA driver version 461.09 release notes. This release includes a few bug fixes, and security updates for driver components.
Version 461.09 WHQL Highlights
This section provides highlights of version 461.09 WHQL of the NVIDIA Release 460 Driver for Windows 7, Windows 8, Windows 8.1, and Windows 101.
What’s New in Version 461.09 WHQL
New Features and Other Changes
- Added security updates for driver components
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.
Using HDR with Games
There may be issues resulting from the interaction between in-game HDR settings and the Windows HDR settings. See the NVIDIA Knowledge Base Article 5072 (https://nvidia.custhelp.com/app/answers/detail/a_id/5072) for details.
Implicit SLI Disabled on NVIDIA Ampere GPUs
Implicit SLI, where the driver makes assumptions with application profiles to achieve GPU scaling, is disabled on NVIDIA Ampere GPUs. Explicit SLI is still supported, where the application knows the SLI state and uses extensions (such as DirectX 12 linked nodes, Vulkan device groups, or OpenGL multicast extensions) to issue commands to each device in the SLI group. See the NVIDIA Knowledge Base Article 5082 (https://nvidia.custhelp.com/app/answers/detail/a_id/5082) for more information.
Image Sharpening Feature
NVIDIA Control Panel Image sharpening controls, including GPU upscaling, are introduced in the R440 driver. Currently, the following limitations apply.
- Scaling is not supported on MSHybrid systems.
- HDR displays driven by pre-Turing GPUs will not support scaling
- Scaling will not work with VR
- Scaling will not work with displays using YUV420 format.
- Scaling uses aspect ratio scaling and will not use integer scaling
- Sharpening will not work with HDR displays
- GPU scaling engages when games are played only in full-screen mode, and not in windowed or borderless windowed mode.
- Some G-SYNC displays have a 6-tap/64-phase scaler which scales better than that offered by Turing’s 5-tap/32-phase scaler.
- To avoid accidentally triggering scaling by applications or DWM, first change to the desired (< native) resolution from the NVIDIA Control Panel and then launch the application.
- Turing’s 5-tap upscaler may not engage on certain monitors depending on the monitor’s vblank timing.
- Turing’s 5-tap upscaler may not engage if the input resolution is greater than 2560px in either the x or y dimension.
- Scaling is turned off automatically when switching display devices.
- “Restore Defaults” option in the control panel currently does not revert the upscaling resolution.
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.
Changes and Fixed Issues in Version 461.09
The following sections list the important changes and the most common issues resolved in this version. This list is only a subset of the total number of changes made in this driver version. The NVIDIA bug number is provided for reference.
Fixed Issues in this Release
- [GeForce Experience]: The FPS counter is activated and the overlay appears on Windows Mail and Calendar applications.
- [GeForce GTX 750 Ti]: Blue-screen crash (UNEXPECTED KERNEL MODE TRAP) may occur. 
- [GeForce GTX 1080 Ti]: The desktop screen may flicker. 
- [GeForce GTX 1080 Ti]: The system may freeze with the screen displaying as solid color. 
- [HDR]: With HDR enabled, black levels are incorrect, notably on LG OLED TVs. [200682795/3201305]
- [Notebook][Lenovo Y740]: The notebook displays corruption after waking from sleep. 
- Blue-screen crash (0x116) may occur upon resuming from sleep mode when three 4k monitors are connected. [3054239/3195884]
Open Issues in Version 461.09 WHQL
As with every released driver, version 461.09 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.
- [X4: Foundations][Vulkan]: The game may crash on GeForce RTX 30 series GPUs. 
- [X4: Foundations][Vulkan]: HUD in the game is broken. 
- [Batman Arkham Knight]: The game crashes when turbulence smoke is enabled. 
- [Detroit: Become Human]: The game randomly crashes. 
- [Steam VR game]: Stuttering and lagging occur upon launching a game. 
- [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.
- [GeForce RTX 3070][Clone Mode]: When the resolution is set to 2560×1440 @ 144Hz, the performance state is stuck at maximum performance. 
- [NVIDIA Turing or later][Windows Movies and TV Player]: When playing a 4k video in full-screen mode on a 2560×1440 HDR monitor, the video extends beyond the edge of the screen. 
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.
