Most tiers of the popular GeForce NOW game streaming service are "sold out," and NVIDIA says it's because of high demand.

Nvidia’s GeForce Now is an easy and convenient way to play PC games if you don’t actually have a gaming PC, or you can’t fit a 30-pound desktop into your carry-on luggage. But at the moment you’re going to have a hard time getting into the service if you don’t already have a subscription.

Most of Nvidia's GeForce Now game streaming tiers are currently unavailable, reportedly due to high demand. Gamers looking to opt for Nvidia's cloud gaming platform will be left disappointed, as five of the eight subscription tiers are currently sold out. Nvidia (via ComputerBase) attributes the current unavailability to high subscriber demand.

Case in point, the first two tiers of NVIDIA's GeForce NOW gaming service are now sold out, as well as a few others. The Valve Steam Deck is also getting its own GeForce NOW app later this year, which can help explain some of this growth.
