The game is lagging and stuttering to being unplayable; FPS drops PC

The game lags and stutters to the point of being unplayable, FPS drops are terrible. The problem is with your game. It's insane that you've let this problem persist for 5-6 months. I've been waiting for a fix, but the team doesn't care. Many people have reported this, but nothing has been done. If you can't fix it, please give me a refund. This game isn't cheap, and PC players are being completely ignored.

System: AMD Ryzen 7, NVIDIA RTX 3050 (laptop), 24GB RAM, Windows 11.

Many players report the same issue online; some fixed it with these steps, but none worked for me.
