A free mod for Witcher 3, by Skypat.
EDFX is a free utility which can add special effects to your 3D graphics. It works with all games that use the 3D rendering engine and is compatible with all resolutions. It can also be used to adjust the resolution and use custom textures.
The effects are applied on a per-frame basis and are updated instantly. There is no need to restart the game and the effects will work for the entire duration of the game.
EDFX is based on the free library Reshade. It has been developed to make it easier for users to set up and manage their profiles. It can also be used to add effects to videos.
