Let's talk specifics. What resolution, what codec, what CPU, what usage. You're pretty vague so far, so it could be that you're watching a software decoded 360p h.264 video on a Threadripper, in that case I agree. It will be a very different situation when you try to watch 4K h.265 / AV1 video on a couple of years old laptop dual-core CPU.

Generally 8-bit or 10-bit h.264, occasionally h.265, at either 1280x720 or 1920x1080 progressive with frame rate usually 23.976. Split and decoded in software via LAVFilters then ran through ffdshow before rendering on Enhanced Video Renderer. CPU anything ranging from an i7-14700K to an i3-2100 (yes, Sandy Bridge). Seriously, decoding video has never been a significant workload for over a decade. >4K h.265 / AV1 video on a couple of years old laptop dual-core CPU. Kindly, why the hell would I even watch 4K video on a laptop? Y'all keep throwing out contrived situations like that, meanwhile I'll be a sane man living in reality and re-encode it (in software, finer tuning of parameters) in my spare time down to 1080p or 720p so I save myself precious disk space and CPU usage while travelling.

  > Kindly, why the hell would I even watch 4K video on a laptop? Because that's the file I have on hand. Why on earth would I re-encode it if I want to watch it once? I also connect my laptop to my 32" 4K screen. There the battery life is not a consideration, but the spinning fan is. > in my spare time down to 1080p or 720p so I save myself precious disk space and CPU usage while travelling. Your use case might work for you, and that's fine, but you claim that software decoding is universally not a problem. But it is, if you don't limit yourself to 720p h.264 pre-encoded at home. Most people are not fine with having to do this and having to limit themselves to low resolutions / bad IQ.

  > Kindly, why the hell would I even watch 4K video on a laptop How about if you have a 4K monitor plugged in? Or if your notebook display is itself 4K (which is a completely valid configuration nowadays)? I have a pretty beefy laptop with an RTX 3080. I regularly watch BDRips that exceed 50+ Mbps, and software decoding even on my 8-core Intel Xeon will cause some stutters. Hardware decoding is just so much faster.
