This happens in multiplayer where I'm the host, but it doesn't require other players to be near. Other players that have been near are unaffected, but get affected by actors in the map lagging because of me.
After I spend sometime near the downtown area of this big desert town in our randomly generated map, my fps starts tanking hard. I normally play with around 70fps on ultra, but it rapidly drops to 30-20, eventually getting to 4 fps. It probably has something to do with loading, because when I sit still and don't move for about a minute, the fps goes back to its normal 70, but the fps drops resume after some time. I really like the new bigger cities but I really don't like the fps drops that (only) I experience. Please let me know if I can provide more information to hopefully get this fixed after experimental goes stable!
