Why things like Smooth, Sculpt and Flat tools lag in an huge terrain?

If you don’t know , i’m an guy obessed with by making huge terrain but if I manipulate that terrain with the Smooth, Sculpt and Flat , they lag more.

My PC specs:

  • Chip : AMD Ryzen 5 4600G with Radeon Graphics
  • RAM : 16GB DDR4 2400Mhz
  • Graphic Card : Nvidia GeForce RTX 3050

This problem is very common when you develop the huge map with terrain

I thought it works by lowing the graphic level , Mine is at max but the problem persists

That happened when I was making my new game based on something I dreamed about while sleeping on 01/30/2025

It was a deep dream, I recreated it in Roblox because it fascinated me :face_holding_back_tears:
I don’t think I’ll leave Studio because of all this until they fix it
