/edit googlil jsem, zde je řešení:


cituji:

if you type within the explorer bar: %USERNAME%\AppData\Local\2K Games\Mafia II\Saves

it will direct you to the save games folder. Within that folder is a file called videoconfig.cfg. Open it with notepad.

Within that file will be something like:
0 0 1680 1050 1 0 0 1

if you change it to:
0 0 640 480 0 0 0 0

Save the file. Exit notepad. Attempt to run the game from steam.

Let me know if this solves your problems.


EDIT: if the file/folder doesn't exist create it.
