U nlike the usual screen recorders, GPU Screen Recorder uses the GPU for video encoding, which keeps the CPU free for other tasks. It works with Intel, AMD and Nvidia graphics cards, and has all the features you’d expect from a modern screencasting app.
It’s available as a Flatpak, so you can install it on any distro with flatpak install flathub com.dec05eba. gpu_screen_recorder .
The app has a simple GUI with all the controls and settings neatly organised in a compact main window, and it’s pretty straightforward to use. You first need to choose whether you want to record a specific window, a follow-focus window, or the entire desktop. Depending on your choice, you then have to pick the window, area size or monitor you wish to record.
You can also optionally alter the video resolution of the recording. Before recording, you can tweak the frame rate and video quality, too. If you want to include audio as well, just select your audio playback device from the drop-down menu. If you switch to the Advanced view, you can alter several more parameters, such as the audio and video codecs.
The app also has an experimental ShadowPlay-like full-screen user interface. Once activated, it runs in the background and can be brought to the front with Alt+Z.
