PC Started doing this artifcating after the 1.12 update this week. The darker the area, the worse it is. Broad day light looks fine. Didn't have this issue before 1.12. I have updated drivers etc.. I also blew out the heatsink on the GPU before i discovered it didn't happen in a well lit area.
Game is unplayable for me now, was on my second run through trying to sneak my way through the game.
