Hi guys,

i am experiencing a weird graphics glitch. Black grids show up where light sections and dark sections intersect. They are visible in particle effects and when sun or the moon shine on a surface. They randomly show up on NPCs, monsters and the floor. It's super strange.
I have tried reinstalling the entire game, updating to the newest driver (removing the old one clean) and every graphics setting possible. The grids still show up and it's ruining my fun quite a bit, especially when it shows up during important story moments. I have no mods installed.
Please help.

Here are images of the glitch. (You will need to click on the images and make them bigger to see it clearly)

For some reason i can't make an URL out of the link, so i attached the pictures as well.
