  • Known issue: 3DF Zephyr and CUDA Toolkit RC 11

    Problem: 3DF Zephyr v.4.530 and lower (All variants) crashes at startup after installing CUDA Toolkit RC 11

    The new CUDA Toolkit (RC 11) installs a dll (nvcuda.dll) with missing file version information.
    See this thread on NVIDIA forums

    Consequently, due to a bug in our code, Zephyr crashes at startup because it cannot find the version information in the file.

    Temporary solution (until patching or new Zephyr versions):
    1) Download the latest drivers for your video card from NVIDIA site:

    (both "Game Ready Driver" and "Studio Driver" are fine.)

    2) Check the option "Perform a clean installation" during the installation process:

    Note: do not use GeForce experience for this process because it might detect that you already have the latest drivers installed.
