Hyper-v virtual machine 100% cpu usage

I am pretty new at creating virtual machines.

I have this MacBook: Apple MacBook Pro "Core i7" 2.5 15" Mid-2015.

I run Windows 10 in a BootCamp.

I installed this virtual windows with Hyper-v inside my windows Bootcamp: https://developer.microsoft.com/en-us/windows/downloads/virtual-machines

I installed a video game inside the virtual machine.

When I run the game it uses up 100% of the CPU and is so slow it's unplayable.

It doesn't matter how much virtual processors I give it.

The same game runs pretty normally with very low CPU usage on normal Bootcamp windows.

What should I do?

I've figured it out.

The problem was that the virtual machine wasn't using the GPU.

I've fixed it by following steps here:

When installing everything normally and not doing any additional setup or tweaking etc. the virtual machine is not using the GPU.

I followed the answer by Victor Miasnikov in the link above.

  1. Start Powershell as administrator and enter: Get-VMRemoteFXPhysicalVideoAdapter
  2. In the returned results check if "CompatibleForVirtualization" and "Enabled" are "True". Mine luckily was.
  3. Enable Host GPU for RemoteFX vGPU. Here I followed the documentation and in my case entered this command: Get-VMRemoteFXPhysicalVideoAdapter -Name \*Radeon\* | Enable-VMRemoteFXPhysicalVideoAdapter
  4. Add RemoteFX vGPU to your VM by entering this command: Add-VMRemoteFx3dVideoAdapter -VMName <vmname>
  5. Open VM Settings dialog box, you can configure RemoteFX vGPU. But I think no additional configuration was necessary.
  6. Start VM.
