A lot of bugs

Hi there . I have purchased the Ultimate edition of Fc26 via Steam so that I can play the game a lot sooner (19th Sep 25) and after the download and few minutes of gameplay the game started to lag a lot I was getting 5-10 fps. Then after restarting the game works as normal till the menu screen after starting any match let it be online or career mode or kick off it starts to lag. I was comfortably getting 120-140 fps in FC 25 and not even a stable 60 in FC26. I have tried everything reinstalling, Turning off strand based hair settings and all. But no use.. 1 get almost 250-260 fps at menu screen and 5-10 fps while gameplay.. EA.. please fix this issue ASAP!!
