Lags when using optics. (Star Wars: Battlefront (2015))

I don’t understand what’s the matter, whether it’s because it’s a beta or a problem with my internet. When I use the zoom on the cycler rifle, there are terrible lags, all the players jerk back and forth, you get the hell out. I tried to change the graphics settings, it's useless. Who else watched this? if there is a solution I will be grateful for the help.
