Shadows are very blurry

I’m building a world, and I saw that the shadows are very blurry. How do I fix this?
I’m using the future lighting and the shadow softness is set at 0.2.

Maybe its because the castshadow property on the baseparts is random? Or maybe try decreasing shadow softness?

Probably your studio graphic mode. What is your studio graphic mode?

The graphics mode is set on OpenGL.

Try immigrating to Vulkan setting.
