PC can't handle 4k@60fps. How can I make it so it can?

[JT!]

i5-4670K OC'ed using the genie built into the BIOS. I believe that puts it to around 3.8/9GHz.

Radeon HD 7950 3GB GPU.

My question is, what is holding playing 4k @ 60fps back? The CPU or GPU?

I figured it was the GPU until I looked at what my cpu was doing when playing the footage and seeing it hit 100% half the time.

Could properly overclocking the CPU help? Or will upgrading the GPU to a EVGA GeForce GTX 770 4GB help out this this? (I literally have this GPU laying around doing nothing).

Oh good lord I almost forgot, I'm not talking about gaming. I'm talking about media.

Try Changing the GPU, It will probably help. As long as i know The GPU is responsible for the "lag". But try closing programs you dont use to see if the CPU is really the problem.
A screen can lead to such stuff too in my experience, If you dont have a screen that supports 4k@60FPS that might be your problem.

It does support 4k at 60fps. And the youtube video did play at 60fps in 4k, just a little choppy here and there.

Then its the GPU, I had my old PC with E5800 and gt220 then the gt220 died and i upgraded to R7 240 and it played youtube @1080p smooth

You could try installing Smooth Video Project.
https://www.svp-team.com/w/index.php?title=Main_Page
It increases the frame rate by generating intermediate animation frames between existing frames in order to produce very smooth, fluid and clear motion.
On my tablet I was getting ~60fps (power config at the std optimized setting not high performance at all) on video playback but had some sound issue wherein it was too low. The installer downloads avisynth 32/64 plus mpc-hc and you may want to check the 64bit box. Gonna give it another whirl to see if I can fix the sound bug. It basically sits in your tray waiting on video playback.The pro version is relatively cheap and provides for youtube support among other options. Of course if you can download the video you could bypass the $ restriction for youtube. I have no clue on how it will react to 4K but it does analyze your video output on first start for it's own optimizations.
My tablet is an I7 @1.7-2.9 GHz so getting almost 60fps was interesting.

Update: 60fps: easy, sound issues persist however

A 7950 shouldn't have an issue playing 4k content...the problem may lay in trying to get 4k out of youtube through your internet. Takes a fair amount of bandwidth to do so, like 15-20mbs+ I hear..

I googled an article for you... https://www.google.com/amp/www.pcwo...r-computer.amp.html?client=ms-android-verizon

It seems obvious to me that if your CPU is hitting 100% when you playback then that is the problem.

First of all, how much system RAM are you running and what speed is it?

Second, your overclock is anemic. You should be able to get 4.4-4.5 ghz on that CPU with a manual oveclock and good cooling.

We know nothing about your hardware except the CPU and video card at this point. Please make a list and include information about the following items:

1. Motherboard make and model
2. Operatiing system? 32-bit or 54-bit?
3. RAM amount and frequency
4. System drive and storage drive(s) information. Spinner or SSD? How full are they?
5. Make and model of CPU cooler or if it is just the OEM cooler that comes with the retail CPU then state that.
6. PSU make and wattage
7. Case make and model and info about case fans. How many intake fans and how many exhaust fans?

If you don't know the information about some of these things then please download and install the free program called CPU-z. Install it. Post back with attached pics of these tabs: "CPU," "Motherboard," "Memory," and "SPD".

Use Snipping Tool in Windows Accessories to crop and save the screen images. Then use the built-in forum tool for locating and attaching pics. You can access the tool with the Go Advanced button below any new post window.

You should create a Signature so that your system information travels with every post you make. That would be helpful to those helping you.

That's a good catch trents...

I just tried 4K 60 FPS video (

). My CPU cores are barely touched... literally getting 4% use on a 6950X @ 4Ghz. like 1 core is used decently a couple others are tickled. That said, my ethernet is going crazy... peaks 30-50mpbs......



When using a quad (I turned off HT on a quad with HT CPU), I am seeing heavy CPU use... to the tune of 25-75%...ethernet is the same as above.

Sounds like you need to enable hardware acceleration. What browser are you using.

 

[wingman99]

I only have 12% utilization with i5 6600k running 4k Youtube.

Good suggestion. A lot of folks have hardware acceleration disabled in browsers because of problems with adobe flash player plugins.

 

[EarthDog]

It's enabled by default.. def. worth it to check!

I've used that before. Although I feel like my pc creating the extra 30 frames would use more power than just streaming the original 60fps.

I have a 60Mb connection.

Chrome. How would I check to see if it's enabled? Will look right into that after I'm done with this post.

32Gb of ram. 1600 MHZ

I have gotten around those speeds before but it was a little unstable. But when I was overlocking it was for a specific purpose as opposed to now where I prefer the stability.

1. MSI Z87-G45
2. Neither. 64-bit.
3. see above.
4. SSD, two thirds full. it's a 256GB drive.
5. Hyper 212 EVO
6. Corsair CX 600W
7. HAF 912. 3 fans blowing in, 1 fan blowing out.

So I'm still kind of confused as to what direction to go here.

Should I be able to view 4k @60fps with my spec?

Seems that my processor peaking at 100% would be the obvious bottleneck, but would a better gpu take some of the workload away from the CPU? I don't want to install that if it's not going to help. Currently my gpu is at 25% load when watching 4k @ 60fps.

Have you tried updating drivers?

 

[JT!]

I try and keep everything updated. Especially the GPU drivers.

 

[NiHaoMike]

Try using youtube-dl to download the video, then mpv or VLC to play it? Not sure how well AMD supports VDPAU nowadays (they're historically quite bad with drivers) but hopefully they would have it good enough to work.

Have you tried rolling back?

Downloading them does help. Uses a little less cpu power so it keeps it from juddering most of the time, but there are spots in scenes where there's a lot going on where it gets a little jumpy.

Have you tried rolling back?

I don't really want to start rolling back drivers until I find the source of the problem.... if there's a problem at all.
