The demo version of Mafia 2 is packed with errors which are concerning to graphics and hardware problems. I guess Mafia 2 is not saving the brightness details of the game after quitting the game once. I have noticed that when I am closing the game then the birhgtness of the screen seems to be bit low then it was earlier. Brightness problem of mafia 2 shows graphic errors like black lines regarding the map black npcs and strange shadows.
