(PC) Optimization issues and sudden fps drops in FC 26

First of all, my system: Processor: Intel Core i7 11800H
Graphics Card: Nvidia Geforce RTX 3050 Ti
RAM: 16 GB

I haven't been able to play FC 26 on this system since its release. I bought the Ultimate Edition, and it's very difficult to buy it at this price in Türkiye, and it's not easy to earn money there either...

Since the game's release, I've experienced issues like the gamepad not working, unfixable FPS issues, freezing, and sometimes the game dropping to almost 5 FPS, mostly after the second half or after the match starts, and even in the lobby, it feels like 5 FPS all the time.
FC 24 and FC 25 didn't have these issues, but FC 26 had almost every issue. Either refund my money or fix these issues. Instead of the Halloween cards update, fix these issues as soon as possible, because I really want to play FC 26 now.
