53sanmon: I have found that the fixes by Wile_ECoyote does not fix all the problems for people who have wide screens. My changes to the ini file is slightly different. I changed the Resolution to 1024 x 768 and added after the last line "Window 1". In addition, you must change the desktop Resolution to the same (i.e. 1024 x 768). DO NOT change the in-game Resolution or your game window gets smaller. And you don't have to modify Nvidia Profile Inspector. You get all the cut-scenes and with no flickering that occurs when starting a new episode. The only down-side is the black bar on the left-side and the right-side of the screen. I played all of the episodes of the game and found no glitches or any problems loading a saved game. My desktop Resolution Is normally set on 2560 x 1440 @ 150% using Windows 10. My Hitman 3 Contracts' Configuration Settings (or ini file) replacement changes are as follows:
