the game works fine if my screen res isnt right making it a little box in the middle of the screen but if i go into the conf file and i change it the game wont open.Anyone know how to change my res and get is to work

The correct way to do this is:

- Go to a folder where you've installed IL-2 Sturmovik: 1946 and edit conf.ini with a text editor.
- Find a line width= and change it, entering width of a screen (e.g. width=1920).
- Find a line height= and change it, entering height of a screen (e.g. height=1080).
- Find a line SaveAspect= and make sure it's set to 0 (SaveAspect=0).
- Find a line ChangeScreenRes= and make sure it's set to 1 (ChangeScreenRes=1).
- Find a line EnableResize= and make sure it's set to 0 (EnableResize=0).
- Save a file and launch a game.
