You can synchronize your Xbox account with GeForce Now
, by Thibaut
Subscribers to NVIDIA's cloud gaming service now have a new feature at their fingertips. An Xbox account can now be linked to a GeForce Now account.
This synchronization offers a number of advantages. For example, players can access games included in the PC Game Pass catalog (provided they have an active subscription). In addition, all titles purchased from the Microsoft Store can be launched via GeForce Now.
