Computer question

I’m wondering if I can get help. I have a pretty good Laptop, but playing Waterpark Simulator on my PC, the further I get in the game the more it lags. I think I might need a PC with more power to run games that have a lot going on. I don’t know anything about computers or what to look for. My current specs are. Lenovo Legion 5 Gaming Laptop, 15.6" FHD 165Hz Display, AMD Ryzen 7 5800H, GeForce RTX 3050Ti, 64GB RAM, 2TB NVMe PCIe SSD, RGB Backlit Keyboard, Wireless-AX, DP, HDMI, Windows 11 Home. Thank you for your help.
