fx files of the mod in game root folder and in the enbseries folder. Also you can edit parameters to your own taste inside integrated editor (show it by pressing SHIFT and ENTER keys together, by default). Modification do not have graphic preset, by default it's ugly unconfigured (unless specified in description of version), so you need to download such presets made by users, feel free to visit my forum. I rarely play games which modify, but when was satisfied enough with result of modding, played GTA5 till the end. Technically, there are many things done already, just they gives more attention to details, so not impressive for the most players. So for me this version is not primary and add features only when want myself. Versions of the mod for GTASA and GTA4 were very popular, but GTA5 not at all because people are satisfied with visuals. Vanilla game looks good and have many features included, but for perfectionists there are always something not good yet, so i hope to cover their needs.
