Locked at 30-40Fps

I’ve been struggling with low FPS— it drops to 2–5 FPS at times. I’ve tried every possible setting, but nothing seems to help. I’ve even attached screenshots showing the game running at 30–40 FPS in cities, along with extremely long loading screens and fully loaded shaders. I’ve tried every fix I could find online and changed every possible setting, but nothing works. I’m losing hope. Other games run perfectly smooth — this is the only one my PC struggles with. Please help!
