Optimization - forge etc

It was fixed in my testing.

Each forge had a burning light and a crafting light. I merged them into one light and with a reduced radius, which improved performance of each forge. I also reduced smoke particles by 25%, which also improved performance. This rendered with less than half the FPS drop on my 3070 TI.

You can also try lowering the graphics Particles setting which will scale down the amount of smoke particles.
