Artemis Qt
What it is
Artemis Qt is a free client for streaming from NVIDIA GameStream, Apollo, and Sunshine servers on Windows, macOS, and Linux. It supports hardware-accelerated decoding, H.264, HEVC, AV1, HDR streaming, and 7.1 surround sound. The client adds clipboard synchronization, custom server commands, one-time-password pairing, an in-stream quick menu, resolution scaling, fractional refresh-rate control, and virtual display management. App launching uses UUIDs when available and falls back to legacy app IDs. The project describes the client as optimized for handheld devices such as Steam Deck, with touch and gamepad controls. Downloads include Windows x64 and ARM64 builds, a universal macOS binary, and Linux x64 AppImage and Flatpak packages. 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, which is described as unstable and intended for testing. The project is licensed under GPL v3.
