4K60 FPS on YouTube uses the VP9 codec, and is CPU intensive because unless you're one of the lucky few to have a Pascal GPU, it's decoded in software by the CPU.
I'm curious to see how various CPUs (especially quad cores with and without SMT, and dual cores with SMT) handle this test video of BF1 @ 4k60 in browser. (note that the actual resolution isn't 4K, but it shouldn't matter)
Check your CPU usage, and look for stuttering or lag. On my 5930K @ 4.4ghz I'm getting mid 20s to low 30s as far as CPU usage goes, and very smooth playback.
It doesn't default to 4k60 so you'll have to manually set it. Also, to get 4K you'll need either Chrome, Firefox or the latest Windows 10 insider's build of Edge.
