Port "emulators/i386-wine-devel" provides script [files/nvidia.sh] to install the 32bit NVIDIA driver additionally to the already installed 64bit NVIDIA driver with same version number.
Latest version of NVIDIA driver is 440.44, latest available version in the ports is 440.31.
But latest NVIDIA driver for FreeBSD 32bit platform is 390.132.
Therefore the patch on port "emulators/i386-wine-devel" does not work when the latest NVIDIA driver is used on a 64bit platform.
The script doesn't work because the necessary libraries are not provided for driver versions > 390.x && < 440.36.
Do note, though, while the 32-bit libraries were recently reintroduced with 440.36 as part of the amd64 package (https://devtalk.nvidia.com/default/topic/1065886/freebsd-solaris/request-include-32-bit-libraries-with-64-bit-drivers/post/5404691/#5404691), instead of updating nvidia.sh it would much more appropriate to pester the nvidia-driver maintainer about properly packaging them.
