You want to tone down the saturation?
If I remember correctly, it's either in the config file that you have to remove 1 line to remove the saturation. I'm not sure since I haven't changed it in a while. There's a readme file with it when I downloaded it, read through it, if not, check the config file itself. There's usually comments inside it, so it will help you out if you ever wish to alter the file.
Or do as Logan says, go to Crymod.com, it's the Crysis modding portal. You'll get answers there as well.
Hope this helps!
