But as said, that was on the landing page with no video playing. What is it even doing there that can load up the CPU like that? I was rather surprised then that playback was actually smooth at least at 480p. Otoh I doubt core2duo had any sort of hardware acceleration for video decoding, but don't quote me on that...

> I doubt core2duo had any sort of hardware acceleration for video decoding That would be the job of the GPU anyway, but H.264 decoding was pretty much standard back then. That's why plugins like h264ify[0] exist for old hardware.

      Hah nice digging, that issue was an interesting read. I will definitely check the IGD version of that laptop.

Make sure to use an ad blocker and turn off that weird Ambient mode graphical effect that just kills framerate. Videos should play fine after that on a Core 2 Duo if you have hardware accelerated decoding enabled.
