GPU Screen Recorder has been released in version 6.0.0 on Flathub.
The tool records the screen using GPU acceleration and works similarly to NVIDIA’s ShadowPlay on Windows, supporting X11 and Wayland on AMD, Intel and NVIDIA hardware.
The new version mainly adds support for Apple hardware on Asahi Linux and IPC support in the command line tool.
Support apple (asahi linux). Switch to software encoding in video options to use it. Add support for IPC in the gpu-screen-recorder command line tool. Slightly improve performance of saving a replay. Minor bug fixes.
