CCC (Cuban-Ultima-Doom-Arch-Assassin-Taowolf-Sword's Custom Crysis Config) is a custom configuration that a lot of people really seem to like, so I decided to try it. I got it here: http://www.incrysis.com/forums/viewtopic.php?id=23117&p=1.
For me it just creates lag, so I want to uninstall it. I just cannot figure out how, since there appears to be no uninstaller.
EDIT- By the way, that level is not really too important anyway. I thing it lags simply because it is a plane mission. But anyway, if I do revert the graphics for that level only, will it mess up my custom settings?
