Severe FPS Drops (5-10 FPS) in every game mode, even in Menus

when playing squad battles, the frames drop from over 115 to about 5-7, which makes the game impossible, most often it happens after the first half ends and the second one starts. I spent a lot of **bleep**ing money on this game and this **bleep**ing **bleep** is taking away my enjoyment of the game.
