Can anyone tell me what settings would cause this?

If I disable my ENB everything looks normal so I don't think it's a mod issue, it's just from the ENB. I'm using Midrahstic ENB.

When I'm outside or in building everything is fine, I've only come across this in the Metro tunnels, and not every tunnel does it either. This is the Farragut West on the way to GNR in the screenshot. Any help would be appreciated.

Edit: after trying a few google searches I found that It's a common problem with ENB where interior cells aren't loading far off objects and the game will use fog to obscure the unloaded areas. It was said in a few places to adjust INI settings and the fog settings in the ENB ini, but none of the changes I make affect it even a little.
