If there is no text appearing at the top left, it isn't ENB. If you have an image adjustment that takes a second to realize itself, perhaps you are using an injected visual graphics mod?
I'm not sure what you mean. A lighting mod?
This is what I use:
I used them all before and they produced the image I wish to go back to. Relighting Skyrim, Quick Light, ELE and Imaginator have been in my mod list since forever, only weathers had changed over time.
I also have SSE Engine Fixes, if that is of any relevance.
I might add that at one point (recently) I had Luminosity, but it made interiors too bright comparing to ELE; the latter is much more realistic and plays really well with Relighting Skyrim.
When I installed Luminosity, however, I also installed the misc Light Editor - these files: JW_Light_Editor.pas and mteFunctions.pas, which are placed in Edit Scripts folder of SSEEdit. I forgot about them when I removed Luminosity, but eventually I remembered and removed them. Could it be that those files have done some damage? Removing them didn't change anything.
Otherwise, I can't think of anything else. The only thing that "injected" changes in my image was ENBoost which is now gone. Do you perhaps have a suggestion on what files I might be looking for? I'm already scouring my Skyrim directory to find the culprit as it is.
Thank you for still bearing with me, DoubleYou, I really appreciate it.
