    100% disk usage when watching 4k videos.


    It started a couple days back. Whenever I try to watch any 4k video on my system the video lags, system goes slow and disk usage is at 100%.

    I have Radeon HD 6670 and 8gb of ram. Should I reinstall windows just for this?

    Thanks.

    It all depends on what program you are watching it on. If your CPU is running at 100%, then the load is too much and it is also doing the right thing in keeping up with the data that it has to process.

    Tried potplayer in HW mode and vlc both lags. Trust me it wasn't like this couple of days back. Now I've noticed cpu is at 100% usage while disk usage is not.

    Hi,

    Have you tried to update your graphic card driver ?

    Yes, it was the only thing I tried but unfortunately 6670 doesn't have much options. I'm gonna reinstall if I can't play 4k videos anymore.

    I suggest you to take a trace with WPR (it's a built in tool in Windows 10). And we can see exactly what's causing your video's glitches. Here is the steps;


    • Open a command line as an Administrator;
    • Type this command "wpr -start generalprofile -start CPU -start gpu -start video"; this will start trace recording.
    • While recording the trace, try to work on your system (launch a video) for 1 or 2 minutes max.
    • Then type this command to stop trace recording "wpr -stop C:\Temp\MyTrace.etl". Make sure the folder where you record the trace exist.
    • Compress the resulting file ( VeryImportant)
    • Share it through https://www.transfernow.net/en/ or any other file sharing platform.


    I'll analyze your trace file and give you a feedback.

    See you

    The potplayer is using 100 % of CPU ! Have you tried to read your videos with others media players ?

    Tried MPC-Home Cinema, VLC, and some other too but only player which is bit better with 4k is : SMPlayer but as I told you before, it was working fine before even on potplayer.
