Google Stadia is a different gaming platform from what we are used to. Given that the hardware is located in Google’s data centers dispersed across the globe, it will be easy to upgrade as needed by the developers and users.

However, perhaps even more interesting is the ability for developers to push their games even further with multi-GPU rendering in the cloud. To demonstrate this possibility, Google partnered with UL Benchmarks for a dedicated tech demo available at the Game Developers Conference 2019.
