Just yesterday, Microsoft announced through the Twitter Xbox account that GeForce Now was being added to Xbox.com's "Play With Cloud" dialog, providing an option besides Xbox Cloud Gaming for Xbox's first-party published games. Since this has yet to be fully implemented, the full extent of this change can't yet be tested. However, from what we know about both services, Xbox Cloud Gaming (formerly Project xCloud) can't provide image quality or input responsiveness on par with GeForce Now, so this is a better choice for cloud PC gamers who own Xbox games.
Xbox Cloud Gaming is limited to 1080p and 60 FPS for those unfamiliar with either service. It is fine by console standards but still inhibited by cloud streaming. Meanwhile, the premium version of GeForce Now can go as high as 240 Hz, implements Nvidia Reflex, and is powered by an RTX 4080 per user. Nvidia estimates end-to-end latency to be 66% lower than a local Xbox Series X. That number is heavily reliant on your Internet connection. This factor is truthfully never entirely in the player's control.
