FAQ
What are the system requirements?
A powerful computer is not needed to use Stratus since games are run remotely on Stratus' servers. Stratus works in Google Chrome on all major operating systems, although some users may need to disable graphics acceleration in the Chrome settings. However, Stratus does require a game controller, as keyboard & mouse input is not currently supported.
How fast is Stratus?
Stratus is capable of streaming at 1080p at 60fps with an round-trip "click-to-photon" latency of as little as 40ms, depending on local network latency and bandwidth. It also starts new streaming sessions in under 2 seconds.
How does Stratus compare to Nvidia GeForce NOW, Amazon Luna, Xbox Cloud Gaming, etc?
Stratus offers comparable streaming performance to commercial cloud gaming platforms, but starts new stream sessions much quicker. Additionally, Stratus is the first fully open-source web-based game streaming service.
What games are supported?
Stratus is capable of streaming most games that run natively on Windows or Linux with controller support. The Stratus library currently contains various popular open-source games including AssaultCube, SuperTux, and SuperTuxKart.
What hardware do the servers run on?
The Stratus servers were designed for and tested on a cluster of 12 BC-250s that was originally created to mine cryptocurrency. Each BC-250 contains a PlayStation 5 APU with 6 CPU cores, an RDNA 2 GPU with 25 Compute Units, and 16 GB of RAM, making them a great fit for game streaming.
Is Stratus available to the public?
Stratus is currently only available to students at Oregon State University. We unfortunately have no plans to expand access due to hosting costs and complexities.
