I tried to make a scene the other day and instanced light2D node during run time. Somehow, the fps dropped significantly.
Do you think I did something wrong?

It's just one instance of light2D node or many ?
Without further details,it hard to tell which is which that result in fps loss.

@@tutortomato You see,
I'm making an enemy scene, the finite state machine to be exact. One of the state is called "magic_casting", during this state the enemy scene will instance a magic circle with a light2D node in it (with fade-in-out animation).
Then I realized that everytime the enemy scene entered this state, the FPS dropped from 60 to under 20.
After long debugging, I found out thst the fps drop happened after I added light2D in the magic circle scene. After removing it, things went back to normal.
So I thought, is light2D node that performance-heavy?
PS: yes, it's only one in each magic circle, and the drop happened even there was only one enemy in magic_casting state

@@agriasoaks6721 one 1 light2D drop that many fps...try using addictive sprite blending for light or the glow effect.
