After using Nvidia Settings app for my prefered settings, they are not retained after reboot. They go back to default. I have had this problem always with linux Mint through many versions. I am now on version 18.1 and Cinnamon 3.2.7. I do save the settings with nvidia-settings Configuration from list on left side of window, then Save Current Configuration button. Although it does create .nvidia-settings-rc file, this file is either not read at login or cannot be read. Here is the file contents:
/home/greg/.nvidia-settings-rc
Configuration file for nvidia-settings - the NVIDIA X Server Settings utility
