After installing the 1.8 patch, it seems like HDR, motion blur, and a few other effects are deactivated in single player regardless of my graphics settings (everything is extreme, GTX 580, any driver). I have not touched any cfg files or modified the graphics through the command-line interface.
A second problem may or may not be related. I noticed that the Statue of Liberty at the start of the game is missing. Yes, missing. The soldiers make the comment about the statue still standing, and all you see is a dark outline (very easy to miss in the night sky) of the statue plus a dull light where the flame should be. It almost seems like a fog is blocking it.
This happens with any nVidia driver I try (GTX 580), but only with patch 1.8. Anyone else seeing (or not seeing...lol) this? Surprisingly, I do not have any major missing textures. If I had not finished the game once already, I never would have noticed these new problems.
