GeForce NOW, the cloud gaming service by NVIDIA, has been around for quite a while. Originally known as NVIDIA GRID, it allowed streaming access to a curated library of games via a monthly subscription business model. Users could play those games from their PCs, Macs, or NVIDIA Shield devices.

At CES 2017, NVIDIA unveiled another version of GeForce NOW. This one would essentially rent you NVIDIA's powerful servers, allowing users to access their existing PC libraries (such as Steam).
