Video chat tool with low CPU usage?
I've tried Google Meet, Hangouts, Zoom, Jitsi meet. All of them hover at around 100% CPU usage for me, especially when there are multiple participants. I teach programming via screen sharing, so it makes my job very difficult. Any alternatives?
Answering your question properly requires more details about your platform (CPU, GPU, resolution, operating system, etc.). If your hardware can offload video encoding from the CPU, that would probably be your best strategy. I would suggest experimenting with OBS Studio to create an CPU-friendly encoded stream from your screen, then exposing that to conferencing software using something like OBS-VirtualCam on Windows or ffmpeg+v4l2loopback on Linux.
