    Same build date as 471.22 (June 29th)... will try it on Windows 11 later today hoping it fixes some of the bugs specific to it! Thanks for the heads up.

    But 471.22 already supports WDDM 3.0. Or am I missing something here?

    CUDA on WSL :: CUDA Toolkit Documentation (nvidia.com)

    4.1. 471.21

    4.1.1. Changelog
    • 7/14/2021:
      • NVIDIA Driver for Windows 10 and later: 471.21
      • Windows 11 officially supported
      • WIP build: 22000, WSL Linux Kernel 5.10.43
    4.1.2. New Features
    The following new features are included in this release:
    • None.
    4.1.3. Known Limitations
    The following features are not supported in this release:
    1. Note that NVIDIA Container Toolkit has not yet been validated with Docker Desktop WSL 2 backend. Use Docker-CE for Linux instead inside your WSL 2 Linux distribution.
    2. CUDA debugging or profiling tools are not supported in WSL 2. This capability will be added in a future release.
    3. cumemmap IPC with fd is now supported. Other Legacy IPC APIs are not yet supported.
    4. Unified Memory is limited to the same feature set as on native Windows systems.
    5. With the NVIDIA Container Toolkit for Docker 19.03, only --gpus all is supported. This means that on multi-GPU systems it is not possible to filter for specific GPU devices by using specific index numbers to enumerate GPUs.
    6. When running the NGC Deep Learning (DL) Framework GPU containers in WSL 2, you may encounter a message:
      The NVIDIA Driver was not detected. GPU functionality will not be available.

      Note that this message is an incorrect warning for WSL 2 and will be fixed in future releases of the DL Framework containers to correctly detect the NVIDIA GPUs. The DL Framework containers will still continue to be accelerated using CUDA on WSL 2.
    4.1.4. Known Issues
    The following are known issues in this release:
    • In-game Vsync fails to cap the frames to the refresh rate of the display only when Gsync is enabled. This will impact DX in-game vsync scenarios on native Windows with Gsync.

    I wasn't even aware of this but dxdiag (on 22000.71) says it does. Good to know. :D
