I've found POIs to lag immensely no matter what settings I use. Seems to be something to do with the new lighting. It reacts strangely, sometimes lagging badly just staring at a wall. Everything else runs buttery smooth for the most part, even getting close to POIs or walking thru Dierville isn't that bad, but as soon as I walk into one of them my FPS tanks! Even the abandoned houses you tend to start by. I haven't even been to any of the bigger POIs yet.. something isn't right here. My machine is no slouch.
