No Map / Black Map?
Remove patch.dat and patch.fat from data_win32 folder.
Apparently this release contains an incomplete patch file and it's causing a bunch of issues.
Game Not Saving?
Try running the executable with Administrator privileges. Also, you must complete the tutorial before you can save as well.
Super dark shadows?
Change the ambient occlusion. Some users have said turning on SSAO helped fixed this problem. Others said turning it off fixed it.
FoV giving you a headache?
Go into "My Games\Far Cry 4\Gamerprofile.xml" and change FOVScaleFactor to 1.2 or 1.3
By default, the FoV seems to be around 60 or 70 which can cause headaches and motion sickness in sensitive individuals.
Sporadic keyboard & mouse controls?
"... disconnecting the controller entirely fixed the problem so if anyone else has that issue hopefully this will help you to fix it."
