UHD is driving me nuts.

Video playback should be done on the GPU. But the problem is not all media players are optimized to play 4K content.

Last time I tried playing 4K video on VLC it ran like sh*t on modern high-end hardware.

Oh no I tried 4 different ones. I do have a question though. Can I simply convert the files to h. 265 to 264 and have great video with the same gpu. Oh yeah to you knuckle head that have bomb posted this posted talking about ps4 and Gameboy, opes I mean Xbox. Take the crop to pm because its not helping me.

 

[Regeneration]

You can try to convert to another format with XMedia Recode. Video encoding is an intensive process that can take a long period to complete.

Unfortunately, 4K playback on PCs isn't that great at the moment. Try free trials of commercial Blu-ray playback software like WinDVD or PowerDVD.

I suggest you seek for other alternatives like a streaming device (like this one) or play directly on the TV (if its a smart one).

What software do you use for playback? Did you try VLC player with new codecs?

 

[Aquinus]

The i7 3930K is a true 6core part, with an FPU for each core and you're OCing. The OP's 6cores share 3 FPU's which limits them for UHD.

Okay, so I woke up, fixed the grocery list and found myself with a little bit of time to check the load average when viewing some 4k content. What I observed is that the load average was anywhere between 2.2 and 3.4 which basically means that many threads were required to play the 4k content (between 2.2 and 3.4.) Mind you that at idle, my machine is usually somewhere at about 0.5-0.75 due to everything that may be going on in the background (like me watching the load average in htop and having chrome open with some static content.)

Also mind you that the 3930k was not clocking up to full speed during this test. It was usually below 4Ghz with very rare spikes to 4.2Ghz on all cores (wat.)

So I used the performance power state for the CPU which mostly keeps it at 4.6Ghz (down to 4.2Ghz occasionally,) and the load average was only 1.7-2.6.

During all of this, radeontop reported about 15% utilization on the GPU when viewing 4k content... at the lowest core power state (UVD is probably clocked up though but I don't have a good way to measure that.)

 

[Mussels]

What software have you used for playback?

MPC-HC, Potplayer, VLC...all should handle this just fine. I could play 1080p H265 content on an intel atom, surely your FX can handle 4k files.

 

[Athlonite]

Are you sure? I've been seeing this kind of problem a lot in my shop and even with a solid GPU upgrade, 4k playback seems to be more than an FX 6core/3module CPU can handle, especially with HEVC.

My mate got an FX6300 + RX580 and has no problems with HEVC 2160p content and I had the FX8320 and an RX580 and basically the CPU did bog all work

 

[TheLostSwede]

@lexluthermiester my comment about the GPU was purely based on video playback capabilities, nothing more. That's what we're discussing here, no? Gaming was not something I was taking into account, as the OP didn't mention it.

And yes, with the right codecs/player, a GPU upgrade should be enough.

Oh no I tried 4 different ones. I do have a question though. Can I simply convert the files to h. 265 to 264 and have great video with the same gpu. Oh yeah to you knuckle head that have bomb posted this posted talking about ps4 and Gameboy, opes I mean Xbox. Take the crop to pm because its not helping me.

Your files are already HEVC X.265 or h.265, hence why you're having problems. MKV is just a container. Converting to h.264 is going to take an insane amount of time on your system and the resulting files will be 2-4x the size on average. As such, it's not a good idea.

The reason your TV plays them fine, is because it has a hardware decoder for HEVC.

MPC-HC 1.92 handles 4K X265/H.265 very well https://github.com/clsid2/mpc-hc/releases/download/1.9.3/MPC-HC.1.9.3.x64.exe

Sorry, why are you replying this to me? I'm not the one having problems.
Regardless, the OPs hardware can't decode HEVC in hardware, so that's unlikely to help.

Could you do the following and report back:
1 Install MPC-BE https://www.videohelp.com/software/MPC-BE
2 Install LAV Filters https://files.1f0.de/lavf/nightly/
3a Go to MPC BE options "Video" and select "Enhanced Video Renderer (Custom Presenter)" from the drop-down list
3b Got to "Audio" tab and select your sound-card
3c Go to "Subtitles" and slect "internal subtitle renderer"
3d Go to "Subtitles\Rendering" and select "Desktop" from the drop-down list
3e Go to "Internal Filters" and disable all filters in the tabs Source Filters, Video Decoders and Audio Filters
3f Go to "External Filters" and "Add filter" select "Lav splitter Source" and then tick "prefer" do this for "Lav Video Decoder" and "Lav Audio Decoder" as well (in that order)
3G Double click "Lav Video Decoder" change "Hardware decoder to use" to DXVA2 Copy-Back, DXVA2 Native CUVID or "none"whichever is able to play your 4K files (Change apply and restart MPC BE each time)

Edit:
Could you also post your data from "dxva checker" https://www.videohelp.com/software/DXVA-Checker

You do realize that's not going to work since his GPU doesn't support accelerated H.265/HEVC decode. It's going to fall back to software decoding and would only work if his 4K content was H.264.

 

[AusWolf]

I want to say Welcome to TPU! However that might not go over well given what I'm about to say...


This is part of your problem. The GTX760 was never designed or meant for 2160p content. It can do it, but only just and requires a solid CPU, which brings us to....

...this. This CPU is not one that can do 2160p content. Sadly, you need to upgrade. A Ryzen 5 1600 and a GTX 980, GTX1060 or better, or Radeon RX580, Vega56 or better would be ideal. You could get away with an AMD FX8350, which would be a drop-in upgrade for cheap, but it's only a stop-gap fix and you'd still need an GPU upgrade as well.

If it's only a matter of video playback, a GPU upgrade is enough. My HTPC plays everything fine ever since I swapped the old GeForce 610 with a GT 1030, despite having a measly Sandy Bridge i3.

The only important thing is that the GPU should be at least a GeForce GT 1030 or better, or Radeon RX 400 Series or better (as far as I know).

 

[ShurikN]

surely your FX can handle 4k files.

It can, but not h265.
Also your Atom must be newer than mine since it cannot do 1080p h265 (bay trail)

 

[Aquinus]

Radeon RX 400

Only if it's a Polaris chip with GCN 4, so an RX 460 or better. Anything lower can only handle H.264 as they're 2nd and 1st gen GCN chips. Just to be very clear about that.

Could he then get an Athlon 3000, the cheapest b450 board and 8G of ram and call it a day. Will the iGPU inside it be enough for his needs?

You know, that's a really good question. Vega iGPUs should be able to handle HEVC however the Vega 3 is a really wimpy iGPU and I have no idea if the UVD part of the GPU is the same as other AMD chips on the same revision of GCN. On paper, it should work.

Looks like it works just fine.

I tried watching Battleship 1080p h265 and it was choppy as hell in gom player but opening it in VLC it ran fine with no issues. MP4 video file extension. Regular 4k video on youtube works with no problem. My pc is not better than OP's.

 

[lexluthermiester]

Short answer is yes. The GTX760 fully supports H264/265. Convert and you should be ok.

Ummmm, that's wrong though, the GTX 760 lacks HEVC support.
It needs feature set F for HEVC in the table linked below, but only supports D. It doesn't even do hybrid software/hardware decoding.
