I have a Windows 10 host machine running Hyper-V and in it I have a Windows 10 VM, which I want to use to connect to my corp VPN so that I can RDP into my workstation. For some reason, the performance of my VM while connected to RDP is just unbearable. Working in the VM is just fine, but once I open MSTSC and connect, the remote machine is like a slide show. I am able to RDP to this same machine outside of the VM, without any performance issues.
Are there any common gotchas here, or something I might turn on (or off), to improve performance?
do you have a high-DPI screen? Like a 3000x2000 pixel screen? – SimonS – 2016-12-14T14:42:17.177
I have been testing it on a 1920x1080 and also 2560x1600 resolution display. So yea, one of them is big, but it doesn't seem to be necessarily worse on either one. – Nathan Taylor – 2016-12-14T14:49:40.680

it's worth a try. try this: https://blog.brankovucinec.com/2016/03/19/fix-remote-desktop-dpi-scaling-issues/

So it would seem that MSTSC is not optimizing for performance. Turning down the color depth in MSTC helps some, but I'm not aware of anything else I can configure. – Nathan Taylor – 2016-12-14T15:31:46.303
1I should note, it still isn't anywhere near as performant a direct RDP from the host machine. I understand that there is some latency with a VM, but this seems excessive. – Nathan Taylor – 2016-12-14T16:10:45.823
