Choppy 8K video playback on RTX 2080 Ti

[AramAz]

Hello,

 

I can't seem to play 8K videos without getting paused or choppy every 2 3 seconds.

 

I have a RTX 2080 Ti, and a Core i7-4790K with 24 gb ddr3.

 

Internet speed is at the very minimum 450 Mbps down and the same for up.

 

I tried with Chrome and Firefox and in both the "Use hardware acceleration is definitely enabled".

 

But it seems that CPU is bottle-necking which makes me think it's not using the GPU efficiently.

 

This is an example video I was testing with:

4K youtube Video

 

A little info about the youtube video, in 4K it show a VP-9 codec being used but in 8K it is this:

 

 

 

Alternatively if I open an 8K video in MPC it runs smoothly with no lags:

Nasa footage from space 8K

 

 

If someone has any experience with this I appreciate pointing out what can be done to resolve this.

 

Thanks!

This is your CPU. It can't keep up with the high amount of data you're putting through the pipeline, while also doing the rest of the processes on the system.

how so?

If that was the case it would have been unable to play the 8k video in MPC smoothly. There isn't a lot of disk activity either so I don't think the CPU is the bottleneck. But thanks.

2080TI doesn't have AV1 support for video decoding only supported on 30 series

this makes a lot of sense, I literally just updated the post to include that information and I saw your response. So I guess I'm out of luck then.

 

Upgrading the CPU and / or GPU should fix it.

 

Thanks

well I hate to tell you this but your cpu can't keep up with yt 8k playback, simply. 

 

keep in mind 8k isn't a widespread standard yet and codecs yt uses might be a bit "experimental" still.

NVIDIA's encode/decode matrix seems rather relevant here:

One can check from there what codecs an NVIDIA GPU can decode in hardware.

Playing in a dedicated video player will send the stream straight to the GPU. Playing in a web browser the player applet will run some stuff on the CPU and clog the processing.

Do you have an 8k display or something? Otherwise it's pretty darn pointless. Almost nobody has any 8k capable display anyways so there will be little optimizations for streaming playback yet. Basically 4k youtube all over again in the beginning. Nowadays you can play it without a hitch on devices that could not play back 4k yt at all in the beginning.

Pretty much... I knew a guy who loved playing "4k" video on his 768p laptop... 

 

However, thanks to youtubes incredibly awful compression algorithms 4k down scaled to for example 1080p looks actually much better than native 1080p due the higher bitrates used.

I have the same problem, and I have 2060 super. I was able to play 8k videos on youtube without any problems, than something happened, a driver update or something else, I'm not sure what it is, but now I have the same problem as you are, and everything else is working fine, the games are working the same as they were before, so it is not the hardware but the software or some change in settings/options. And the reason I like to play 8k videos on 4k monitor is because they look much better than 4k videos, like the person above me said. And important thing to mention is that I did not have any hardware change in my system. I have ryzen 3600, 16g ram and 2060 super.
