Sudden onset dark in game

[Tetrol88]

So - quit out of game, all was going fine.

Restarted game, start menu, ENB loaded, normal. Loading screen normal brightness.

In game indoors close to pitch dark - in game menus normal. Brightness slider in normal position, and works, but even at maximum is still a lot darker than usual.

ENB working, and environment light settings are as they should be,

Zoned outside - everything is sort of "misty". Loading screen was normal.

Tried different saves (ones I had previously used) - all dark (inside) or misty (outdoors).

Exited and did the following, trying loading a save each change made

1) Total PC restart

2) Reinstalling all light associated mods, including weather mods

3) Reinstalling ENB

all with no effect

 

Tried console "SG 1.5" to increase gamma - worked indoors, but outdoors was now bright and misty. Returned it to 1.

 

Any ideas please?

 

Edit - Noticed it is still dark indoors with ENB off as well (and still a white out outdoors) Tried different ENBs and no change.

 

Well - "fixed" - Nice of NVidia to update without informing me it was doing it. It doesn't even save your settings, so activated aliasing etc which stop your ENB from working. Oddly kept a Skyrim preset, but installed everything to default in it. In the meantime I stupidly managed to overwrite my preferred ENB settings.....
