Ran around Balota in the dark with a flash light (yes I actually did that AND I am still alive, though down to 4k health as I crossed a Zed on a ladder before I realised what I was doing.. ouch). Zero artifacting from the static military corpses! Got on a server in daylight, there is the artifacting again.
(Damn you steam, before it updated I had no artifacting (and didn't have the two new graphical options), then it updated, buggered my files for a brief spell, allows me the two new options in Video settings but then gives me the artifacting. Makes it more hazardous in the military areas at least
