Sorry for the dumb question, but I'm kind of new to using Sweetfx. What is the difference between Sweetfx preset in the presets folder and Sweetfx settings in the main game folder?

SweetFX settings are the settings. Without it you don't have SweetFX.

Ok, easy enough. What do the presets do?

Presets are modifications to default sweetfx settings...

What rishabh47 said, presets are modified settings that other people create to make the game look a certain way.

Ah, ok so they work hand in hand with the settings. Thanks for clearing that up everyone

You have to try reshade 3.0, it's easier, cuz it's in real time: https://reshade.me/
