Game in Slow Motion (Packet Loss)

Ok so, The game is pretty great to play, but I'm having an issue that makes me stop playing the game, which is the packet loss,  when I have lots of players around me, my game just starts to getting slow, when I start a mission, the game looks fine because when you're doing a mission, you cant see other players, but when I finish the mission, the slow motion come back, and dont stop, already tried everything and nothing changed, no problems with my internet also, great speed, i dont really know why that happens only for me
