FPS much lower after coming back – did the game get heavier?

Heyy, I just came back to the game after about 2 years and I’m struggling with my FPS.

My specs:

• RTX 3060 12GB (OC)
• Ryzen 7 5800X3D
• 32GB DDR4 RAM
• NVMe SSD

I’m running the game on medium - high settings with DLSS Quality at ultrawide QHD, but I only get around 55–70 FPS. I swear I used to play at ~140 FPS with DLSS off back then.

Did the system requirements really jump that much, or could I have some setting messing things up?
Then I see a Youtuber rocking 180 FPS WHILE RECORDING at 4070. There shouldnt be that much of a difference or???

(Current settings: SSAA Off, DirectX 12, RTX Off.)

Thanks a lot! 🙏
