    I second that there is no other windows 3D accel working other than passthrough at this time. I have tinkered with a number of hacks, but they all had their failures! I am curious though, what sort of issues you are having getting passthrough to work? I have been doing it for the last 5 - 6 years on several different systems; 4th gen i5 with an early version of VT-d... this was a bit of a pain, but stable in the end, and now a threadripper system where it has been an absolute delight. These days I always have windows running on a VM with a second GPU and I just swap monitor inputs and use "barriers software KVM". Its freaky simple, stable and useful!

    There is no working 3d accel in qemu except for hardware vgpu solutions

    No. Qemu doesn't even have support for it yet, so there is no real way to test it regardless so I doubt anyone is working on it at the moment. I think it is a safe assumption that someone may pickup the project in the future. but as of now, none that I am aware of. Viogpudo needs to get modified to work for vulkan passthrough (the virtio-gpu driver for windows), and then you need a userspace vulkan driver for venus.

    I agree; I don't think Zink should be baked into a program.

    In general, I don't think Chrome really needs a Vulkan stack, though I wouldn't complain if it got one.

    Oooh lol. Yeah, I can definitely see the benefit in that.

    Are you asking whether Google could integrate Zink or are you asking whether Zink would work with this? If the former, I'd agree with what Quackdoc said.
