c# - Unity VM crash (looks like acceleration issue)

There is a problem with run Unity project on Hyper-V virtual machine. To make a long story short, my Unity project is working on my PC, but doesn't work on a VM. I described this in detail here:

https://stackoverflow.com/q/65550732/5709159.

I found a crash log where Unity wrote everything. Because there is a restriction on number of chars that I can post on stack overflow I uploaded the full file here: https://drive.google.com/file/d/1xAtTUytNGH7WFSSIr8WGotCDrvQKW9f-/view, and here I just posted the last part of this file:

The execution fails when it tries to enable or access a dedicated graphics card/driver:

Dedicated video D3D11 device creation failed (error: 0x887a0004).
[h264 @ 00000126dd07d5c0] Failed setup for format dxva2_vld: hwaccel initialisation returned error. Failed to get HW surface format.

As of July 14, 2020 RemoteFX vGPU is disabled due to security concerns. Though, if you are only using trusted software and sources, you can re-enable it with the guide microsoft is giving especially here. If you want, you can learn more about the adapter here: here If you don't want to enable this, you have to configure DDA - just as Grizzle suggested.

If you really want to use GPU passthrough, I can recommend you this guide on running a Windows GPU passthrough with a Linux host system.

If a Linux host really isn't an option for you, go with this guide for DDA by microsoft. Though be aware: There are some bugs with it (like this one with WinServer v2019).

Theres even a whole guide on this by the microsoft-team found here. But I strongly recommend to use LinuxKVM for that stuff - it's up to you.

Caveat: afaik the GPU gets disabled on the host and is used by the VM from now on. So you need to either live with that, use a noGUI (linux-server build f.e.) env. for the host or have 2 GPU's (dedicated and APU style f.e.).

TL;DR: You don't have a graphics card enabled in HyperV or it's not functioning. Ensure D3D11 (DirectX 11) is usable inside the VM and by the passed GPU.
