Yeah, but can it run DOOM?

The author of this text describes their experience in building a cloud gaming service using LiveKit's SFU-centric model, after initially managing to play DOOM over LiveKit during a hackathon. They discuss the various technical challenges they faced and how they were resolved, such as capturing inputs from the client-side browser and sending them over LiveKit data channels, or encoding the screen on the VM and piping it back into the LiveKit room. The author also mentions their success in playing Portal 2 co-op with a friend using this setup, despite some minor issues like stuttering controls and unresponsive buttons. They acknowledge that there is still room for improvement and optimization, but overall they consider this project a success.
