Gameplay FPS drops to 10 at the start of a match or after half-time

In Ultimate Team online game mode matches, my FPS sometimes suddenly drops to 10 and stays at around 5-10 FPS no matter what I do. This occurs either at the start of the match when loading in, or upon entering the Half-Time screen. This makes the game completely unplayable and the only way to fix it is to restart the game. Sometimes it fixes itself upon returning to the menus after the match, but it is inconsistent. I have tried everything in order to avoid this bug, including locking my settings files in local app data, changing all my graphics settings to low and even changing my resolution to 1280x720 (even tho I play on a 1920x1080p screen), changing the render scale, etc.

Please fix your broken game and whatever glitch is happening in the background causing this to happen. I don't know what it is exactly maybe the game is overwriting the graphics settings at half time and turning everything to ultra which then makes my PC have a stroke. This is an embarrassment of a game and an embarrassment of an issue to be happening FROM RELEASE all the way until 4 months into the game's life cycle...
