unplayable with my acer nitro 5

When it doesn't freeze during screen changes, I have another problem when there are many monsters, lowering the fps to -3.

I reached the endgame and my balls swelled. I have a lot of pain. Money back
I don't want to destroy my PC because of poorly programmed software.
