Photoshop operations (color range, blur etc) extremely slow on Azure Win10 VM with GPU support

Because of lack of GPU on my computer, I needed to use Photoshop on Azure. Everything is super fast but when I use any kind of effects, and operations like color range Photoshop too slowing, lagging, and waiting. I've changed the Photoshop GPU preference with all possible combination, closed, and opened again but nothing changed.

This problem occurs on virtual machine with no GPU support also. Existing of GPU support changes nothing in short.

I am connecting with VM with RDP.

Whats happening to Photoshop on Azure VM?
