I can't believe I'm watching Youtube completely fluidly on this 2010 thinkpad running #OpenBSD.
I mean, of course, it's 720p, and it's using mpv streaming via yt-dlp, not the bloated hellsite youtube dot com, but STILL.
P.S. Tried youtube dot com, just out of curiosity. Set it to 720p, and after the initial thrashing once I hit full screen, it was dropping about one out of every four frames, with the CPUs nearing 100% utilization. In contrast, with mpv, 50% CPUs utilization (core 2 duo), 0 dropped frames. And that's with streaming the video from youtube with yt-dlp, not pre-downloading it.
