Hyper V video performance

Hi All,

I have searched the net a lot but can not find any useful info regarding Hyper V and its performance.

I have:

AMD Ryzen Threadripper 2950X 16-Core Processor

Gigabyte X399 Designare EX, bios F11e

RAM 64GB, PC17100

AMD Radeon R9 200 / HD 7900 Series

Samsung SSD 970 Pro 512GB

Problem is that Hyper V is really very slow. Mainly video performance is very bad.

Any idea's what I can do to get better video performance, or is this just an Hyper V issue?

Thanks in advance.

It depends on the Virtual Machine you setup... remember that each VM has their own Driver Stack, by Default (unless you use pre-set such-as: 

PS C:\> New-VM -Name VMDemo -Prerelease

The above will simply pre-setup a Full Windows 10 Pre-Release Environment., but you can always add a Graphics Card via below.

Now you can manually add this from within the VM or as part of it's setup with

PS C:\> Get-VMRemoteFXPhysicalVideoAdapter -Name *AMD* | Enable-VMRemoteFXPhysicalVideoAdapter

If you don't it will simply (Software) Virtualise the Hardware,. so that means the CPU not GPU will be running it as the VM has no idea there is a Graphics Card connected. 

Thanks for your reply.

Unfortunately video is still poor.

Just using a text editor, typing text, moving around with the caret (arrow keys) is just so slow :-(.
