Don’t get me wrong; OBS is a great tool to record your screen, regardless of what operating system your using. But you might have noticed something while trying to record gameplay on Linux: the CPU gets taxed quite a bit, even when using the NVENC encoder on NVIDIA GPUs. As a result, the framerate drops. Introducing a new, open-source screen recorder: gpu screen recorder. The developer of this project claims this significantly reduces CPU usage, “at around 0%” due to keeping the window image on the GPU and sending it directly to the video encoding unit with CUDA.
