I thought I would post this here instead of in the bug tracking area, because there might be a simple solution to solve the problem.
When I am in DLCs via the capital wastleand (all up to date, tested with just TTW 2.2a active) I get this interior fog stuff appear, that you sometimes get inside of massive internal spaces, but it is present in exteriors whilst outside in DLCs. It really ruins the DLCs for me.
Is this a persistent feature that cannot be removed due to the nature of mashing Fo3 and FNV together or can it be overcome somehow?
My settings are all on max for everything, including the LOD distances. So it is not that, and it is definitely not any other mod besides TTW.
I had a similar problem with a FNV mod called dry canyon, the mod author then released a fix for it, so I think it can be solved, If anyone has the final solution to this problem please post.
