It seems after 30 minutes or so of play that some textures start to have a rainbow pixelation effect and is consistent until I restart the game. What seemed most strange to me was that the objects have the rainbow pixelation at a distance, but when I approach it disappears. I have looked online for a while and some people claim it's a problem with AMD hardware or drivers. My GPU is an RX 480 (8 GB) with latest drivers. The pixelation happens to random objects in game, but the objects will consistently be pixelated until I restart the game. I don't have any graphical enhancers like ENB or SweetFX installed. As far as I can tell the pixelation started recently for me, but has been a problem for other users for a long time.
