"Grate effect"

[Thaliur]

Looks like the normal maps or textures could be damaged. If that's the case, a reinstall should help.
It could still be damaged hardware, but here in Germany we have a nice proverb for these situations that roughly translates to "Let's not paint the devil on the wall"

Does this also happen in nightvision, and does it look the same then, or in lower resolutions?
