The company has released a new deep-dive video showcasing the console's speed in comparison to the Xbox One S, and has been testing it on The Outer Worlds, Obsidian's 2019 RPG that suffers from some long wait times.
Xbox Series S Speed Showcased In New Video
You can check the video out for yourself at around the 3:50 mark.
The Series S loads the game within 12 seconds, while the One S takes almost a minute. That's a hefty 77% faster.
The game is also being enhanced for Series S and Series X, although we don't know if the demo shows the optimised version or not.
Interestingly, it also seems as though the Xbox Series S will be faster than the PlayStation 5.
It's been quite the week for Microsoft after the company revealed both Xbox Series S and Xbox Series X will both launch on November 10, along with pre-orders beginning on September 22.
The tech giant has also sweetened the already saccharine Xbox Game Pass subscription by adding EA Play at no extra cost, while also opening up its all-in-one finance option, Xbox All Access, to more countries.

Meanwhile, Sony has been silent on pre-order information, although a gold PS5 is available for the princely sum of £7999.
The Japanese firm has, however, been very vocal about the benefits of the console's SSD drive.
A recent blog post highlighted just how developers are using the speed afforded by the technology, while a new trailer also offers a look at the advancements made in the leap to a new console generation.
