gpu-screen-recorder is a hardware-accelerated screen recorder that uses GPU encoding (NVENC, VAAPI, or AMF) for minimal CPU impact. It is designed for recording gameplay and screen content with low performance overhead.
Key features include a replay buffer (recording the last N seconds like instant replay), support for both X11 and Wayland via portals, and efficient hardware encoding. The replay buffer can be triggered to save via SIGUSR1 signal. The tool supports multiple monitors, specific window capture, and simultaneous system audio and microphone recording.

Requires compatible GPU with hardware encoding support (NVIDIA with NVENC, AMD with VAAPI/AMF, or Intel with VAAPI). Wayland support depends on desktop portal implementation. Some desktop environments may require additional configuration.

gpu-screen-recorder was created to provide an efficient, GPU-accelerated alternative to software-based screen recorders. It's particularly popular among Linux gamers for its low overhead and instant replay capabilities.
