4k movies uses a lot of CPU

[Teague]

Tested with MPC-HC and the 4k mp4 file uses 20% and the other 4k mkv file uses max 5% CPU.

Seems MPC-HC works really fine, but why are the others so much worse?

MPC-HC has built-in codecs for GPU offload. There are many different codecs out there, trying to be more efficient and/or providing better quality. While playing a video, right-click on Renderer Settings > Display Stats to see what is going on under the hood.

My old Phenom II at above 4ghz clock speed cannot even playback 4K YouTube without frame drops.

Your network is the culprit. Try playing the same clips offline.

As others have said, codec packs should be avoided.

Somehow potplayer is working fine again with 4k content, didn't change a thing. Only problem is now that subtitles are out of sync. But I can manually sync it with potplayer.
VLC isn't fixxed.

Where can I find renderer settings?

Interesting.. I have phenom x4 965be@ 3.9ghz..when I was on Linux 4k playback was a nightmare. Going to Windows I don't have trouble with 4k playback anymore.

4K? Try 8K 60fps: https://youtu.be/PNumqSKv1Vc

Also, I've noticed Edge does a MUCH better job than Chrome when decoding these videos IME.

8k is rip my pc.

Does some1 know why suddenly potplayer can handle 4k content without me doing a thing. Checked if there was windows updates, but there weren't.
No driver update for my GPU.

And why potplayers 4k content the subs are out of sync, it wasn't before.

You should be able to play youtube 8K videos. GTX 1070 is just as capable as my card.

My Core 2 Quad desktop with a GTX 1060 6 GB can smoothly play downloaded 30 FPS 8K youtube videos with MPC-HC at 12% CPU load. Movies & TV app does even a better job at 5-6% load.

It's even able to play them straight on youtube; it's just that my bandwidth isn't enough for realtime playback.

Basically my video card's video engine does all the heavy lifting.

EDIT: I even downloaded and played that 8K 60 FPS video linked up there. MPC-HC managed it at a 19-25% CPU load; Movies & TV app did it at 5-6% load.

Can you download from YT?
But when I play it on YT, it just crashes my pc.

How do you do that then?

Ohhhh I'm going to have to try this

I downloaded them with Internet Download Manager's extension using Firefox.

It shouldn't crash. First, we have to check your card. Did you download DXVA checker? I posted its link in page 1 with a screenshot. Please do that and post the screenshot here.

 

[Teague]

I downloaded the dxva checker, want to post the image here, but i do not know how to do it here.
But it's totally the same as yours, that's what I can tell you, but I would like to show you the pic.

 

[Ketchup]

You need to use another site to host your pic and then provide the link. This is the one I always use:

[eddman]

Seems fine, even for 8k. Maybe there is some underlying issue with your windows installation?
What browser did you use for YT 8k? Try FF and Edge too.

 

[Teague]

WoW, used Edge. No problems at all with 8k content on YT.
Is Edge now better then Chrome?

I just reinstalled windows 10. What could be problem?
There where no issues during installation.

Is there a 4k media player that uses your gpu instead of your cpu?

MPC-HC and Potplayer, I think. They almost doesn't use any CPU now anymore.
I don't know how you can check that. Can you see it somewhere?

 

[eddman]

I really don't know why this happens with your system. Could it be that there is a conflict between the video card's and CPU's video decoders? I can't say; my CPU doesn't have an iGPU so I have no experience with them.

Saying that, your CPU's decoder should also be able to deal with 4K videos.

I don't know how you can check that. Can you see it somewhere?

Usually players have an indicator for that somewhere, but a better approach would be to use GPU-Z. In the "Sensors" tab, there is an entry called "Video Engine Load". During CPU-only playback, it'd show 0%. When using hardware video acceleration, it'd show a percentage depending on the video's complexity.

Both DXVA checker and GPU-Z have a GPU selector at the bottom of their windows. See if both Intel and nvidia are listed. Check which one gets used during video playback.

 

[UglyDuckling]

Nope, even my XEON can't playback 8K when the 8K video is buffered in YouTube fully.

... CPU usage hit's 100% that's at 4.3ghz + HTT.

Using Chrome though without GPU accel.
