No, vfio is still the most recommended option.

This is essentially something like VirtualBox or VMWare 3D acceleration - the host is still the "owner" of the GPU, and has to juggle receiving OpenGL commands from the guest and sending the render results back to it, with lots of overhead. But easier for users than setting up passthrough or using proprietary GPU virtualization solutions.

People pointed out that there is a similar project for Vulkan, already being used in production for ChromeOS, called Venus. Should be the one to watch nowadays.
