Game looks blurry or cut off in Windows? See here.
If you have issues with the game looking blurry or the display being cut off under Windows, please try the following:
Locate the OOTP 18 shortcut (or the OOTP18.exe), right-click it, select properties, select the compatibility tab and toggle the setting for high DPI scaling. Restart the game. That should fix the issue!
