youtube buffers every few seconds when playing 8k 60 fps videos on my pc, why? how to fix?

[Napoleonic S]

I remember this wasn't an issue when I built this pc back in 2019, I'm using 3900X 2070S 32GB RAM NVME SSD with windows 10 pro... and I can see the internet buffers status on the playback bar is fine...

yet the video keep buffering every 3 seconds or so... and I swear I remember this wasn't an issue before, I don't remember when this issue started, possibly after one of those sneaky chrome update or/and windows update.especially the H2 2020 update or something.

any clue as to what's going on here? how do I fix this?

8k 60 is on YouTube now?

8K yes, 60 no, not even close.

Have you enabled gpu hardware acceleration?

Control panel/system/display graphic settings. This should make the gpu do the rendering instead of the cpu, gpu is much better at it.

(assume your running latest driver).

is that on windows? that would be hw acc gpu scheduling and it's already ON.

hw acc on chrome also already turned ON

now I noticed though, in 8k60 mode, before buffering the video frames are also stuttered... now this indicate something in my hardware isn't working correctly...?

seriously though, anyone know any other site with free 8k60 video streaming?

yeah got the same problem on ry ryzen5 3600 too
my cpu just goes up to 100% usage and also got those same loading times, even tho my connection is fast enough to load that video.
Maybe this isn't well optimised yet.
And there are probably only like 1 or 2 8k60 videos on youtube anyway

DuckDuckGo served me up a bunch of 8K videos. Here's one but the music's a little dreary so I muted it. 4320p60 right? No buffering, no stuttering, full screen mode.

Older gtx 1080 (running at 84-86% usage, cpu around 4%), Firefox browser, Windows 11, 200 mb/s Internet. Another v8K vid on birds had my cpu at over 90% and gpu fluctuating betw. 35-55%. So it's not the same usage from video to video, it seems.

Don't know if it's approp. in this case but in general, flushing the dns cache helps with buffering.

Type cmd into Search, right-click to run as administrator.

Paste: ipconfig /flushdns

DNS has absolutely nothing to do with this.

No, I didn't think so but thought I would mention anyway. But in general, flushing dns helps,with buffering, at least for me.

My hardware was showing fluctuating hardware use (up to 100%) but my specs aren't as high as OP's. Videos do seem to differ in what resources they consume.

[_I_]

if the dns flusher doesnt work, try a dns plunger

or dns plumber

or seriously, change the routers dns servers to 1.1.1.1 1.0.0.1 (cloudfare) and/or 8.8.8.8 8.8.4.4(google)

they are faster than most isp dns servers

On Comcast I've also always had to just disable the firewall in the modem too

Hmmm but my cpu and GPU aren't getting stressed out whatsoever... And I didn't have this problem when my pc was new.

Then either the service (Youtube) or the connection between you and the service (the intenet) is to fault.

General FYI: a new NVIDIA WHQL driver is out: 472.12

One can check if hardware acceleration is enabled in the browser. Someone did mention that the 8K videos are still relatively new and need further optimization. Maybe that's part of the puzzle. They surely aren't created equal in what resources they consume.

I replayed the NY vid and got an isolated instance of buffering lasting a second or so. Nothing occurring every x minutes, though. In my case, I think it was due to the gpu spiking.

Which is also what i previously suggested but seemed to have been ignored.

Even Youtube has Peak Usage times which can affect the playback of large content at certain hours of the day, if lower res content does not give the same results then that should be enough of a hint that its likely caused by Youtube.

Well I tried to do that at different times and the result is the same.

And I have stated repeatedly that all I see on my screen is that the video seeking and buffering bar DO NOT indicate that there is any insufficient connection speed.

Please, do you people get it? The light grey buffering bar can be seen moving at way ahead of the red playback bar and the video would still be experiencing 3 seconds interval buffering and stuttering.

Well thanks everyone, looks like this is a mystery we have little hope to solve atm. At least now I found another person with ryzen pc experiencing the same issue, maybe this is amd specific issue? Who knows, maybe if more people can join this discussion and mention the same issue with amd cpu then we can start understsnding what's going on.

More likely network farts or router issue.

When was the last time you wiped the routing tables and flushed the DNS?

Youtube uses multiple connections to download into the buffer, the gray bar you see represents an approximation of how much and what parts of the media have loaded.

The gray bar being ahead of the playback doesn't mean you actually have a continuous buffer - there can be gaps, and if so it will stutter while it retrieves those pieces.

You can watch it happen live by inspecting the network requests - you will see
"/videoplayback?" requests sent while data is being loaded into the buffer

Youtube sometimes also releases new features slowly to certain groups or random groups of people - then they collect data from the playback and use it to analyse whether the feature is working / how well it is working / bugs, etc. You can see the active client experiment ids
