AMD is pushing out a new Radeon Software Adrenalin 2019 Edition driver release (19.2.2) that adds official support for the Radeon VII graphics card. In addition, the latest driver release is optimized for Metro Exodus and a few other games.

The Radeon VII is AMD's newest graphics card, based on its 7nm Vega GPU. It's still not widely available—there is no stock on Amazon or Newegg right now—but you can snag one if you're quick on the trigger, direct from AMD. Stock comes and goes, though. At the time of this writing, clicking the "Add to Cart" button on AMD's website brings up an "out of stock" message, with the promise that "additional inventory will be available soon."
