Apex Legends Gunfight Lagging/Stutter

First of all, I'm really enjoying this game. Good on the devs!

I'm running the game more than fine, I'm able to pull 120+ fps, but when somebody uses their ultimate, or when I get shot or start shooting at someone my game goes to 5-10 fps for a good 2 seconds. And it happens very often and constantly in a match. However if nothing is happening, or I just shoot my weapon out of combat my fps is fine. If I'm playing as Blood Hound, and I use my ultimate, the fps drop lasts the entire time of his ultimate. I've tried all the optimization tutorials I can, even tried using half V-sync and running the game at 60fps cap. It will still happen. I've tried changing my resolution. I've concluded that I don't believe my pc or the game settings is the issue, and I do not know what to do. Its really hard to make big plays in this game when I'm afraid to fight people because I'm at a disadvantage in every fight.

My specs are...
