What Artemis Qt is
Artemis Qt is a free client for connecting to NVIDIA GameStream, Apollo, and Sunshine servers on Linux, macOS, and Windows. It streams with hardware-accelerated video decoding and supports H.264, HEVC, AV1, HDR, and 7.1 surround sound. During a stream, users can open a quick menu, scale resolution, adjust fractional refresh rates, and control virtual displays. The client also syncs clipboard content between client and server, runs custom commands on Apollo or Sunshine, and supports one-time-password pairing. It launches apps by UUID when available and falls back to legacy app IDs otherwise. The project describes its interface as optimized for handheld devices such as Steam Deck, with touch and gamepad navigation and power-efficient rendering. It supports multitouch and gamepad play for up to 16 players, as well as local co-op. Downloads include Windows x64 and ARM64 builds, a universal macOS binary, and Linux x64 AppImage and Flatpak packages. The project is GPL v3 licensed. AV1 requires Sunshine and a supported host GPU, while YUV 4:4:4 support is listed for Sunshine only. The latest release page is a development prerelease, and its builds are described as unstable and intended for testing.
