Advanced Lightnings VFX [Niagara]

Can you have more than 1 lightning bp on a level? It seems if i have 1 out , i can see the lightning , but if i add another , and both auto activate , its like the FPS just freezes up or something. Yea this thing is really jacked . You move it just a little and you cant see it anymore , its extremely hard on FPS when trying to run it. Freezes up the whole project.
