afi

and tell me please, how to use sweetfx

I've used this preset: https://sfx.thelazy.net/games/preset/1841/

And this is sweetfx: http://www.mediafire.com/download/55w1kcn99k4nths/Swfx_Injector_20130601.zip

You have to put both into the folder with your ss2.exe. And you have to rename the preset to SweetFX_settings.txt. You probably should save the original settings.txt in case something goes wrong.

Much thanks
