Replace the "visualsettings.dat" in the following location:

(mods)\update\update.rpf\common\data

**Installing any mods in the "mods" folder is better because then you will have the backup of the original files**

Though the backup is given here, most mods don't have the backup file, so you should use the "mods" folder.

**DON'T ENTER THE ONLINE MODE WITH MODS, OR YOU WILL GET BANNED**
