Why does the windows server 2012r2 graphical shell slow down when connected via RDP?

Question

RDP

Good day everyone!
On Hyper-V 2012r2 there are 2 virtual machines. I work on a hypervisor and virtual machines through RDP.
When working with a hypervisor, the graphics are drawn smoothly, without delays, but when connected to a VM (the same WinSrv2012r2), the graphics are very slow, the windows move frame by frame. This question is relevant, because the virtual machine will have 1C for RemoteApp.
If Hyper-V connects to the VM through the management console, then the graphics work smoothly, although it is simplified there.
The server is connected via a shared cisco switch with a 10-gigabit port.
The video card on the host is Matrox G200eR.

Answer 1

Try to enable the best performance for the user in performance.

Answer 2

There is not enough memory for the virtual machine, or processors (vCPU).
