I there a config file that turns things on and off, like film grain for example?
Yes, most of them are in SweetFX.txt. At the top of each section next to the effect name there is a "0" for off or "1" for on. See highlighted "0" below.
////-------------//
///**EXPLOSION**///
//-------------////
#define USE_EXPLOSION
0 //[Explosion] //-Explosion : Scatters the pixels, making the image look fuzzy.
//>Explosion settings<\\
#define Explosion_Radius 2.0 //[0.2:100.0] //-Amount of effect you want.
#define Explosion_TimeOut 0 //[0:100000] //-Defined Toggle Key will activate the shader until time (in ms) runs out. "0" deactivates the timeout feature.
#define Explosion_ToggleKey RFX_ToggleKey //[undef] //-
You can then change the amount each setting has using the #define values, edit the value to a value between the range. So radius for example here is set at 2.0 which is between 0.2 and 100.0. Changing these values will have no effect if the main on/off value is set to off.
If you have ED running and the SweetFX.txt file open in notepad, you can make changes and each time you click save the whole reshade preset will reload with that setting added so can see straight away the effect. Hope that makes sense
