When vid_wideaspect 1 in use, cfg_save saves wrong values. It saves the recalculated values .. thus, they get recalculated again on next cfg_save.
.. are wrong.
I also confirm this issue.
Moreover, it recalculates it based on 16:10 ratio as I read from the help, but many monitors are 16:9
fov is calculated after resolution in ezQuake 3.0 so this bug is invalid/fixed in upcoming 3.0. Closing
