What Artemis Qt is

Artemis Qt is a free client for connecting to NVIDIA GameStream, Apollo, and Sunshine servers from Linux, macOS, or Windows. It streams video with hardware-accelerated decoding and supports H.264, HEVC, HDR, and 7.1 surround sound. The client also includes multitouch and gamepad support, with local co-op support and gamepad play for up to 16 players.

During a stream, users can open a quick menu, adjust resolution scaling and fractional refresh rates, and control virtual displays. Artemis Qt can sync clipboard content between the client and server and run custom commands on Apollo or Sunshine. Pairing can use a one-time password. For launching apps, it uses UUIDs when available and falls back to legacy app IDs otherwise.

The project describes the interface as optimized for handhelds such as Steam Deck, with touch and gamepad navigation and power-efficient rendering. Downloads include Windows x64 and ARM64 builds, a universal macOS binary, and Linux x64 AppImage and Flatpak packages. Artemis Qt is licensed under GPL v3. AV1 streaming requires Sunshine and a supported host GPU; YUV 4:4:4 support is listed for Sunshine only. Custom app ordering and input-only streaming are planned.

Who it suits

Artemis Qt suits players who want to stream from a GameStream, Apollo, or Sunshine server to a Windows, macOS, or Linux device, including handhelds such as Steam Deck. Its clipboard sync, server commands, virtual display controls, and local co-op support also suit users who want client controls beyond basic streaming.
