It sure does! At the lowest, cloud gaming is on-par with constantly streaming very high-quality videos, using seemingly a few GB of data per hour. When the cloud gaming services say they need a 15Mbps internet connection, they mean it, so you can extrapolate from there. While all of these services are figuring out the optimal quality and compression options, it’s fair to look at some of the long-time players in media streaming as the ideal for what cloud gaming data usage could be, but know it will be more. If you’re looking to take advantage of the 4K options where available, expect the data usage to go up to match.
