I have an NVIDA Gforce 560 TI. I recently upgraded to driver 301.42 and I am afraid it may be the cause. This occurs in videos as well, so I know (think) it's not mod or game related.

Is anyone else experiencing this?
Is there a tweak I need to adjust?

I am not that savvy about this stuff and the dark nights and dungeons are just horrid. I don't know what to do. I just let the NVIDA site do it's thing on the update. So, I assume the install was clean.

My game is running the best it ever has. I don't want to revert to an earlier version but these solid gray nights are a real mood killer.

These shots may be hard to see but any advice will be greatly appreciated.

The clouds have no detail. It's just solid areas of blue and gray. http://cloud.steampowered.com/ugc/955010953823362306/132181A3177EC9F0A73D3CCB7B1A17A07C880880/

This is in BFB. It changes as I get closer. http://cloud-2.steampowered.com/ugc/955010953823361786/DFB4607AD60142205CBF03E7DE217AA17F4B4E91/

This is after I take another step. http://cloud.steampowered.com/ugc/955010953823363365/A29FD7268C745BC77D1C8B67CF8A8D3C1E7A1346/
