HOW TO:

Extract and copy "Engine.ini" file from .rar archive, and paste into your C:\Users\"YourUserName"\AppData\Local\MGSDelta\Saved\Config\Windows folder, overwriting already existing file.


NOTE:
If it is hard for you to find the said folder, just paste %LOCALAPPDATA%\MGSDelta\Saved\Config\Windows into your Windows Explorer's path bar.
