A great advance. As of Jan 28, 2021, it's still pretty buggy and incomplete, but not enough to deter from a good experience. I'm upgrading my rig to 16 G of RAM, and an SSD to speed things up. I'm getting by with an Nvidia GTX 770. If I stick to 1080p, I'm ok. If I hook up to 4k, it never gets off the ground. I'll have to research the minimum req's for that...
