Game running on 15-20 FPS max

Can anybody tell me how ea can just ruin their game every 2 weeks? This joke of a game is just unplayable I tried everything to improve fps but then i realized my pc is not the source of the problem. Every other game (more graphically demanding) running smoothly without any problem. I start my game with locked 60 fps in lobby then i want to play match which drops my fps to 15-20 and when I leave the match (because its unplayable) I have 15 fps even in the lobby. EA please fix your game, I want to play it earlier than in April when you start taking minimal care for your game on pc.
