On Windows 11:
- Download and install Nvidia GPU Driver for Windows: https://www.nvidia.com/download/index.aspx
- Download and install CUDA Toolkit for Windows: https://developer.nvidia.com/cuda-downloads
NOTE: Nvidia Official doc says, the GPU Driver includes "CUDA Support", which is very confusing. It doesn't mean CUDA is included in Driver. What included is only some support files, not CUDA itself. You still need to install CUDA separately.
