At 0.16.51, graphics-quality can be set to very-low, but 0.17 does not have this option.
But there is this option in the config.ini comment, but it has no effect after the modification.
This is a small problem, maybe 0.17 does not support this option, this is forgot to update the comment.
I have not verified if other comments have options that are not supported. You can check it out.
