Having Huge Problems with EA FC 26 In PC

Since I enter the first time, the game is very lagy, during all tipes of games online and offline the game starts in slow mottion! Also during online games the controller disconnects and i can't do anything!
This are huge problems that should be corrected, there lot's of people that buy the ultimate edition have early acess and since the game launch there is no oppurtunity to try this game!
