Is it actually using hardware decoding? The player should show "H/W" in its status bar when that is active.

This videos is 8K at 60fps and 10bit. Are you sure you previously played files with exact same properties? This one is much harder to decode for the hardware than for example a 30fps video. I am not sure if your hardware even supports this.

Can you give me a link to that video?

Yes,The player show "H/W" in its status bar when that is active。

This is what happened after I reinstalled the new version of K-Lite Mega,It used to be good.

I just added another nvme hard disk, which made me mistakenly think that too many nvme hard disks occupied the PCIe channel of the graphics card, resulting in insufficient bandwidth of the graphics card, which caused this problem,Because this was not the case before.

I removed the nvme hard disk and rolled back the NVIDIA driver to rebuild the previous environment. Finally, I thought the problem was K-Lite. I installed it version by version, and I found this problem.I'm now in the K-Lite version 1653 and decoding is completely good

Here is the video .torrent]LINK

I suspect it might be an issue with the video renderer.

MPC-HC menu > Play > Filters

Click on LAV Video Decoder. Verify that it uses DXVA2 Native (because Copyback is slower).
Then click on MPC Video Renderer to open its settings. Test if you get better performance when you uncheck the option "Use Direct3D 11".

It can be determined that the problem lies in MPC video renderer.

When use Direct3D 11 is selected, the problem I described will appear in any version of K-Lite.

Thank you

Should I report the problem to the producer of MPC video renderer?

Can you try version 16.6.8? The updated renderer has some potential performance improvements for D3D11.
http://codecguide.com/klcp_beta.htm

Press Ctrl+J to show the renderer debug overlay. Make a screenshot for me with both D3D11 enabled and disabled. That contains useful information for the developers. I can contact them about this issue.

In the Windows Task Manager (Ctrl+Shift+Esc) you should see GPU usage details. Do you see any big differences with D3D11 on/off? Make a screenshot of that as well.

Finally test if D3D11 hardware decoding (instead of DXVA2) in LAV Video Decoder make any difference.

Can you also do the D3D11 decoding combined with D3D11 in renderer?
