Microsoft revealed on Feb 24, more details about Xbox Series X — 12 teraflops, hardware accelerated DirectX raytracing, variable rate shading, etc.
One of the most exciting feature among them is Smart Delivery. It allows you to buy game once, and play it on Xbox One or Series X, and always get the right version on that platform.
But it’s up to game developers to decide whether to use Smart Delivery. Microsoft has confirmed that the titles from its own Xbox Game Studios, including the incoming Halo: Infinite, will support this feature.
On 25, CD Projekt Red said they will do the same with Cyberpunk 2077:
