Valheim is the goddamn worst about this. It's so bad that I bust out laughing the first time I looked into the distance.

The DOF in Valheim is ludicrously aggressive, especially since it's not on a set distance but based purely on where your cross-hair is aimed. 
The result is that it will quickly and constantly change with even the slightest movement just because your crosshair touched a tree or bush for a moment that was very close.

I genuinely get motion sick from it so turn it off, thank god that unlike some games it's actually a separate option, I hate games that just make one general post-processing toggle.

On the other hand, turning of DOF makes the grass pop in very obvious.
