There's always been this visual glitch when you take a high zoom sniper and observe buildings on long distance, they appear to be glitchy and constantly jittering... But it's not always the case, sometimes it's alright and looks clean and perfect but sometimes when you prone it goes crazy. Here two pictures and you can see and compare them http://imgur.com/a/DXsAI It looks like it has LOD problems (it's easier to notice it with a video)
