I have the same processor and an RX570. I can pass through the dGPU to the VMs and keep the iGPU for the host, but the reverse was not possible for me.
Does the motherboard matter for this? Mine is not so fancy.
I have probably a couple of more Linux/BSD VMs than here (with some with GPU passthrough and one or two for ARM crossbuilding and so on) but only 2 Windows VMs - the only 2 I have legitimate licenses for.
So now what will I run on my one plus one? ಥ_ಥ
I dunno how the guy managed this for 10 years for so many devices. I can't even build my own ROM for just this phone. ¯(ツ)/¯
