Google Stadia made a splash at GDC 2019 not because of the technology involved, but simply because of Google's official involvement in the console gaming world. Similar game streaming services have been available for years with GeForce Now and Playstation Now being the most notable. The former, however, is still in its beta phase as Nvidia is continuing to work out the performance kinks and quality of service.
For readers interested in beta testing GeForce Now, just leave a comment on our Facebook post here saying how you think the service can improve your gaming experience or what games you'll be trying out. We won't make users jump through any hoops or follow our pages to enter the drawing, though that would of course be appreciated. We'll be messaging two random users with a beta key at the end of this month for them to experience GeForce Now themselves.
Of course, all users can still request beta access to GeForce Now via the official Nvidia page here. Please note that the service is only available in North America and Europe as of this writing.
GeForce Now differs from Stadia in several ways. First, it only supports a specific list of games as stated here. Furthermore, users must have already purchased the standalone game on PC in order to stream it through GeForce Now. Thus, the service will likely be trivial if you're not already a Steam user with a sizeable library of titles. The service requires Mac OS, a Windows PC, or a Shield TV console with no Android or Chromebook support at least for now.
