For paravirtualized hardware rendering you can use virtio-gpu. In addition to Linux, a Windows guest driver is available but it's highly experimental still and not very easy to get working.
What's the best solution for remote viewing with virtio-gpu? I vaguely recall that it had some incompatibility with spice.
I have a bunch of qemu/kvm virtual machines for various tasks. For two of them I decided that graphics performance needed to be at least OK and ended up buying and passing through old Quadro cards. It'd be lovely to not have to do that.
