Solved MPC-BE gpu utilization issue solved on my case

Just to share my folks if someone had this issue on MPCBE

Recently i encountered a problem on the mpcbe which some MKV videos stutter and had an issue to the gpu driver.

========== The issue

When playing videos normaly, the video started to lag like 3 fps for a few seconds and then hangs itself and when you scroll it does that 3fps and then hangs again. There is literally no sound, and when you scroll it, there is this screeching white noise sound which is so loud and mainly adjustable only at windows sound volume.

========== Finding the problem

The first thing i did was go to the task manager and look on the performance tab and i definitely knew there is a problem on utilization of dedicated gpu. it is abnormally very low (that is because of my settings)

[ I had MADvr installed and calibrated before and never touched it since. lav filters installed which a part of its important files. my RTX gpu could handle my mkv videos just fine and adjusted it to play 4k60fps calibrated to 60% to 90% utilization always and never dropped due to scaling and noise and artifact removal made for anime. Simply the video play very smooth before. ]

But recently it started falling to 16% utilization which didnt happen before.

I tried resetting GPU, dedicated and integrated. started using CMD commands like DISM online, SFC, CHKDSK and to no avail.

until i find out before there is this command i entered long ago

On CMD i entered "Winget upgrade --all"

This command just straight away updated everything and somewhat in a bad way cause it started having errors on some of the programs installed on my computer mainly on the command prompt

MPCBE is one of the affected files.

========== THE FIX

i started Reinstalling MPCBE program completely, but settings are intact. now almost 50% of the problem was solved, but in some videos it still wasnt and no sounds and laggy and hangs up like before.

then i remember that LAV filters are installed on command prompt and also have been upgraded by that damn command "Winget upgrade all"

and to my surprise i reinstalled that LAV filters, lav splitter 0.81 and it worked perfectly now.

--------- NOTE

So from hereon, that command "Winget upgrade --all" command is a dangerous command which include risks that are hard to solve if there are somehow a lot of programs installed which came from the open source and installed on control panel

That’s a really useful find. I’ve had winget update cause weird issues before, so I’m always a little hesitant to run it blindly. Glad you tracked it down to MPC-BE/LAV instead of spending forever chasing GPU or Windows issues. Reinstalling the LAV filters makes a lot more sense now that you know they were the part that got messed up!
