I noticed this same issue on my "new" monitor in 7 Days to Die, even though I haven't noticed it at all in any other game. I have played more than 20 games published in the last 3 years on this same setup (so I know the problem CAN be avoided), but 7 Days to Die is the only one where I have noticed this, and it's bad enough to make the game unplayable.
What seems to cause it is what joshwa0816 suspected earlier, Black Smearing (my in-game experience with 7 Days to Die was almost as bad as the example in the video he linked). It seems to be a problem with almost all VA panels out there, and considering they are going to be more and more popular because of their low price for an otherwise great screen, this should be relatively high on the things to look into for the development team.
What made it better for me (but did NOT fix it), was to set Contrast 10% lower, and Brightness 10% higher from NVidia Control Panel. It does make the game look flat and dated in comparison, especially the shadows, but at least I can now play for over an hour in one go (I actually got a migraine attack after 10 minutes of play).
