ARKHAM KNIGHT_BaseSystemSettings.ini

This is edited .ini file of Arkham Knight. This helped me to run it on Nvidia 730M. Ofcourse, there is reduction in quality but the game is smooth and playable. This for those who are really interested in playing the game for the story and gameplay rather than graphics.

Rename ARKHAM KNIGHT_BaseSystemSettings.ini to BaseSystemSettings.ini
Go to the Arkham Knight Installation folder and then go to:
/Engine/Config
and replace the file BaseSystemSettings.ini (Make a backup copy of your Original file)

Also the in the Game: Graphic Options set resolution to 1280x720 and make other settings either low or off.
