Battlefront 2 Game lagging, stuttering and freezzing after phasma and finn updat

Since the finn and phasma patch, my game is running really bad, my game is running at 1285 clock speed and 1099 memory clock speed. The gpu is running at 100%. The main menu is smoother than ever (only lags at opening crates), but then when it comes to gameplay it's horrible, multiplayer, arcade and campaign all lagging, stuttering and freezing. The game looks like not usi g the full gpu usage. Because the temp is too low to be true 55 - 57 at maximum overclock, ehich is not normal at that speed playing fifa 18 is about +60 degrees C. And yeah No problem with other games only Battlefront 2 (also no problem with the first battlefront)

Things that i already tried
1. Setting all setting to low
2. Checking the power Plan
3. Uninstall and reinstalling 3 times in a week
4. Reinstalling the gpu drivers
5. Reinstalling other games too, to make sure
6. Trying to contact ea with chat for more than 3 times with no answer
Please i really this game to be fixed, i bought this game to play at mid semester holiday, and now here we are at mid semester holiday with a unplayable game
Thanks
