Failed to find adapter on Dx12

[madmaxio]

I have vmware based virtual machine with win 10/ Dx12 driver, wgpu can't find any adapter both native and on the web. Also I have dx-diag output.

Your DX12 doesn't support even Feature Level 11_0. We can't reasonably run on it, sorry!
Updating your OS may help.
Getting DX11 in #2443 would also solve this.

This means wgpu works fine with DX12, but I need latest update for DX12?

(just some random thoughs, I don't know if they gonna works)

Updating drivers is almost always a good idea, but in this case I think the problem is more particular and related to virtualization.
I haven't used a vmware machine in a long time, but I think you can proceed with these attempts:

• in case you do not already do a search of all the adapters to get a clear idea if even if the wgpu does not find an adapter at least someone visible you have it on the vmware (poll_all method here)
• i have no idea how vmware can communicate with the gpu, but it might have a software layer, in this case it might be an idea to play with the force_fallback_adapter option

I see drivers are pretty old, will try to update them to make things clear.
