This is a screen recorder that has minimal impact on system performance by recording a window using the GPU only, similar to shadowplay on windows. This is the fastest screen recording tool for Linux. It's currently limited to nvidia GPUs.
This screen recorder can be used for recording your desktop offline, for live streaming and for nvidia-like instant replay, where only the last few seconds are saved.
