Sunshine serves as the engine for low-latency streaming. Originally developed as a cross-platform alternative to NVIDIA’s now-discontinued GameStream, Sunshine is hardware-agnostic, supporting NVIDIA, AMD, and Intel GPUs. It functions by capturing the host PC's video output, encoding it in real-time, and delivering it to a client running . Its open-source nature allows for deep customization, enabling users to stream entire desktops or specific applications with minimal overhead. The Role of Gamescope: The Sandbox Environment

For the first time, a Linux gamer can say not "it works if you tweak it," but "it works better here than anywhere else." The sunshine has finally broken through the Gamescope.
