Technical Help: My Game is Constantly Dropping Frames Mid-Fight Since Yesterday

This has been happening a ton the last 2 days on Infinite. The game will be running at 165 fps and then suddenly drop to 12 when I see enemies, and the only way to revert to 165 is to tap the xbox button on the controller and back out of the game bar on pc. If anyone knows wtf is going on please help.

I called it packet loss, but if its something else please let me know. My PC shouldn’t be the issue, as I have been running games like COD and Warhammer 40K titles on high texture settings with no issues, and Infinite has only started doing this since maybe yesterday.
