Hello everyone!

I have recently been experiencing issues with youtube 4K playback. It all started about a week ago and now everytime i load a 4K video on youtube, i get greeted with an error message that flashes for a milliseconds then the video plays at 4K with all kinds of stuttering (thats when the 4K resolution has actually loaded), i will include a pic of the message that flashes and i will upload a short video of how 4K playback now is. Its annoying and im worried if there is something wrong with my GPU. Games are not affected at all and even 4K videos on my computer play normally without any issues. What do u guys think the issue might be? I'm using the latest Google Chrome browser. The GPU is watercooled and has been watercooled for more than 2 years straight (since i bought it in july 2012) and the temperatures have since then never gone above 62C so i dont know.

The HD 7970 us grossly underpowered to handle 4KU UHD video

Maybe in 4-5 years cards with enough GFLOPS will come to the market for 4K and then 8K will start to come to the market

A stock 7970 at 1000MHz would have a load of less than 25% decoding a 4K video.  Well within its capabilities.

There's still quite a lot for the CPU to do, so that can make the video perform poorly, especially as the display resolution goes up.  At 2560x1600 fullscreen with an i7 3930K at 4.6GHz, 4K video is smooth for me (though YT with hardware acceleration is borderline).  With a 4K monitor, the CPU might have a hard time keeping up.

Ive been able to play 4K videos on YT since youtube implemented them and havent had a single issue, with both a 120hz 1080p monitor and with my current 1440p monitor. The issue started just about a week ago and no settings were changed whatsoever.

No its not the cpu. This is clearly a gpu issue. I have the same cpu as u and also @ 4.6ghz and my monitor is 1440p and i havent had issues at all since i bought the card. It all started last week. I have even connected my gpu to my 4K tv before and there was nothing the gpu couldnt handle. Its weird that this iis only happening with youtube videos which are alot more compressed than original 4K vids (which run very smoothly).

Can you point me to some specific videos that are giving you a hard time, so I can see if I have the same problem?

4K videos aren't as demanding as games in 4K, 7970 should be more than good enough for that (especially at youtube's low bitrates) so the problem has to be somewhere else.

It's gone now suddenly. All 4K videos are playing normally now. It might have been a minor Chrome issue that has been fixed now? I really dont know.
