Over at its booth on the show floor, Microsoft has been showing off a particularly impressive tech demo for the Xbox One it had made with the help of a little US government agency known as NASA.
The aim was to test the limits of the new Xbox's horsepower by simulating - get ready for this - 35,000 light-years of space.
Cloud? Nahh, space!
Microsoft went to NASA to use its vast database, which has details of every part of the solar system - planets, asteroids and comets included. They then teamed up to replicate in a crazy-impressive simulation harnessing the new console's power.
"Each of the 40,000 asteroids are calculated and rendered, presenting its time and place to a high degree of accuracy," said Xbox One engineering manager Jeff Henshaw.
Henshaw added that the Xbox One has the ability to feature "10,000 or 100,000 enemies in-game" without buckling by working alongside the cloud.
