Toggle SweetFX on/off = `(~) = tilde key

Extract SweetFX into the following directory = \Steam\SteamApps\common\SS2\

I've tweaked this preset using a bunch of Graphics Mods, too many to list, I found the source files on a Reddit Post

CTRL + F (Find) a post by the user name "Genghis_Tron187"  he has an all-in-one download link, that's what I used

Just extract the file into  \Steam\SteamApps\common\SS2\DataPermMods\  and enjoy!!
