your task manager doesn't have GPU informations and you have a really high CPU load if this is hardware decoded. so this isn't the newest version windows 10 isn't it?
can you click on - LAV Video Decoder (internal) and check which decoder is used.

try to run GPU-Z go to the graphic card page and search for a small "?" on the right side next to the PCIe... press it and and run the test for a couple of setting and check the PCIe speed.

the card is a kalmx correct?

well that doesn't mean your screen can do this refreshrate.

you can check your possible under "windows key" type in display settings -> display adapter properties -> monitor.

or in your GPU driver (afaik AMD doesn't have an option for it they removed it with the crimson driver)

did you disable the GPU trackign in the task manager?

the decoder image doesn't help if you are not running a file at the same time.

and now the important part you only have PCIe x2 v3.
what board are you using? you most likely have the card in the "wrong" slot or something even worse.

x2 PCIe is usually the processor mounted in the socket badly or bent pins, each PCIe lane from the CPU has its own pins and each lane can fail individually. I have never heard of a motherboard with an electrically PCIe x2 x16 slot (only M.2 was ever x2) but I have had x16 slots turn into <x16 slots due to CPU socket mounting issues. In my case it was not enough force pushing the CPU into the socket due to trying to run without a heatspreader but I have heard of cases where bent pins or slightly off use of the retention mechanism caused the same thing.

chill easy to know with the name of the board and...

PCIe 16 slots with mechanical 8x and electrical 4x are so common...
adding a 16 x electrical 2x is easy task for a mainboard creator.

It could also be the video card mounted into the slot slightly badly. I have had a card pulled forward a little at the screw so the back wasn't quite in the slot correctly, it would only run at x4 until I reinstalled it.

Edit: the x2 PCIe connection is definitely your issue, x2 PCIe 3.0 is simply too slow for good playback. Your motherboard does have a full PCIe 3.0 x16 slot so it should be running x16. x8 would be fine, even x4 might work, but x2 is too slow.

https://abload.de/img/gpu71p50.png that would be the interesting part.

the lavfilter you ahve open is not the lavfitler that is in use.

both of these doesn't matter anymore.
so ignore them you have way bigger problems.

first i personally would reset the bios, check all settings in it and retry it.

than i would remove and add the GPU again and retry it.
other GPU...
CPU...
other CPU...

RMA the board...
and/or something in between the lines.

why is your target 3397x1911?? Doing that downscale will certainly push most cards on the edge, over it.

I may have found the culprit, and i doubt this will be any help to Rippner.

While i thought it was Mediaportal, i couldn't work out why.

Compared to MPC-HC it was twice as long, as in always over 20ms compared to 10ms with MPC-HC. At this point i remembered that MP19 was pre-release, and i'm sure there were some MadVR fixes/changes.

The issue also happened around about the same time as i installed MP19, so i'm abit annoyed at myself that (after putting the blame on drivers, then the OS, then Lav and MadVR) the player was the last place i looked.
Re-installing MP18 has dropped it back down to under 10ms and i managed 20mins of video without dropping a frame so looking good.

I am a big screen HTPC guy, so MPC-HC is something i have limited experience with, though i did notice that it uses it's own version of LavFilters, that confused me for a bit lol.

I feel there should probably have a general troubleshooting post for dealing with these sorts of basic issues that people need to go through ideally before asking.

A 2x PCIe link is not a Windows problem.

Try reseating the CPU.

madVR - high quality video renderer (GPU assisted)

Hi!

I reencoded a video to 1080p 1920 x 940

Why is it Madvr upscales it back to 1920 x 1080? How do I prevent this?

That would be your player, MPC-BE has some 'do not scale' options for small changes like that.

madVR simply does what the the video player tells it to do. Is your video still flagged as 16:9? Is your player set to simply stretch to fullscreen?

Thanks a lot. Changing the flag to 1920x940 or 2.0 did the trick

this will not result in CPU usages and not in 20 ms+ finalsteps and freaking 100 ms for chroma.

Agreed! The user has many, many problems going on, including some serious hardware issues. The x2 on the PCI-e slot certainly throws some red flags up about that.

@Rippner

use mpc, madvr, etc in 64bit,

you can also check performance under different player https://mpv.io/
