Researchers help video gamers play in the cloud without guzzling gigabytes. Duke Today, May 20, 2015. Gamers might one day be able to enjoy the same graphics-intensive fast-action video games they play on their gaming consoles or personal computers from mobile devices such as smartphones and tablets without guzzling gigabytes, thanks to a new tool developed by researchers at Duke University and Microsoft Research. Named “Kahawai” after the Hawaiian word for stream, the tool delivers graphics and gameplay on par with conventional cloud-gaming, while using one sixth of the bandwidth.
