Quoting: ShadowPlay for Linux? Make Screencasts With GPU Screen Recorder —
GPU Screen Recorder is a lightweight screen recorder for Linux that works like ShadowPlay on Windows. It keeps everything running smoothly using your GPU for recording, so your CPU is not overloaded. Whether you're on X11 or Wayland and using AMD, Intel, or NVIDIA graphics cards, this tool has you covered.
One of the most excellent parts? You don't need an internet connection to record and capture your screen offline. It even has an "instant replay" feature, similar to ShadowPlay, letting you save the last few minutes of gameplay so you never miss a crucial moment.
