How to rotate HDRI in real time?

Rendering

Hi,
I am learning Rhino via an online course.
In the tutorial(1st video), the teacher rotates the round panel then the viewport real-time rendering will follow up, but when I do the same, there is a time delay before I let the mouse button go.

It happens in all HDRIs including imported ones.

Maybe this is related to my computer, so I put my specs here:
AMD 3700x(speed up to 4.4), RX580 GPU with 8g VRAM, 32g RAM, Windows 10.

Thank you!

In the tutorial:

I’m not sure of the problem, but just to check;

Are both viewports set to the same display mode? (Rendered Display Mode)
