Still having the same problem (Map is dark with a single lightray) and I can't seem to find the Hook Patch to download it. Can anybody help me ?
Same problem here, just got the game, everyone here seems to having the problem since 2008 so I don't have much faith in them releasing a fix.
The patch linked above isn't accessible any-more, does anyone know of any other workaround to this annoying issue?
EDIT: FOUND A PATCH: http://www.giantswd.org/?file=60
FIXES BOTH THIS PROBLEM AND ANOTHER PROBLEM INVOLVING VSYNC/MOUSE SENSITIVITY. I RECOMMEND IT.
