I moved from vbox to qemu/kvm. Windows UI was much faster on vbox thanks to its 3D acceleration solution. That is kind of translation layer which utilizes/shares your host GPU. I couldn't get such performance gains with qemu/kvm. Possibly it is available with dedicated GPU passed thru to the guest, but my laptop only has one GPU taken by the host.

This is indeed a real sore spot for qemu/kvm. VMware has good tech here as well.

One thing you may be able to do is use GVT-g to use a time slice of your Intel iGPU and pass that through. But it doesn't work on all Intel iGPUs and will never be available on newer Intel hardware.

I have read a bit about SR-IOV and MxGPU of AMD, but they also seem to be not available in consumer grade Ryzen 7 laptops. So far I need Windows to do some minor MSVS dev or Edge web testing which is absolutely manageable with software emulation.
