Cloud gaming promises an amazing future: Instead of being tied to a console or a powerful computer, with a game-streaming service you have the freedom to take your games from one device to another without buying multiple copies, installing more software, or losing your progress. And you can enjoy visuals and performance that aren’t limited by the device you play your games on. In theory, cloud gaming offers a way for you to pick up your games from anywhere on the planet, on any device you own, with virtually no downtime in between.But after more than two years of research and multiple rounds of testing, we’ve found that even the most popular cloud gaming services can be difficult to predict or rely on, and it’s tough for us to recommend any of them. In our most recent round of testing, we were impressed by one service: Boosteroid. However, we tested it in only one geographical location — though we plan to evaluate it again with a larger pool of testers to see how it fares under a more diverse range of network conditions.
