Previously I could watch 4K videos perfectly fine with 1050ti. Now I have new videocard and even at 1080p I'm getting skipped frames. And 4K it's totally unwatchable. Tried different browsers: chrome, chrome canary, edge, edge chromium, firefox, opera. It stutters everywhere. Hardware acceleration on/off makes no difference at all. CPU usage 100% all the time. Sometimes, GPU load is 30% and 4K videos are pretty watchable for 10 seconds or so, then it drops to 0% and so on...

I watched Peru video and it's impossible to watch at 4K. But it was silky smooth with 1050ti, I know it, because I was testing new monitor.

I think whats going on here is that the rx590 doesnt support vp9 decoding, so its falling back on your cpu.

The 1050ti, however, does.

AMD used to have a page like this, but then they got rid of it for some reason. At least I cannot find it.

edit:

You can get a plugin for chrome to force h264 fallback on most videos, however, some features such as 60fps or higher resolutions might be missing from some.

And I think google fixed it, I reported them about this issue, and now I can watch 4K almost perfectly. No more 100% CPU load, GPU is in use also.

After having a look around, it appears that the hybrid acceleration for vp9 only supports the base codec, profile 0, not profile 2 which google is moving it. 

Whatever fix you have is most likely coincidental
