Same trouble here, always when go to the planets (large areas) or when on a fireteam and need to change to another area. The single player experience is impossible and the multiplayer is annoyning (for me and for my friends) I already open all ports, change all cables and conections possibilities, some people even told me to change my IPS (but for just one game...nah....) The problem don't occur when on the tower or crisol, (small areas full of people connetcted?), is something related with "taking" a playing stance, this stance aparently don't stabilize for my setup..
