Scan your harddrive for bad sectors.
Scan for damaged Windows files.

Madvr uses the private nvidia api to enable hdr.

Can someone or madshi show the api?
I want to make a script for other things to enable hdr by command line interface.

@Madshi can you post the API, please?

Thanks, that's what I'm looking for.

The white papers even bring the code ready.
I'm just wondering, the APIs are part of nvidia drivers now? Or those need to be installed?

If I'm getting this right, all I need to do is copy and paste the code to the player and it will trigger HDR.

Also again, much appreciate the help.

No, you don't need to install anything else.

So today I checked. Playing video on my kodi box vs playing with kodi using madvr/dsplayer.

And it seems Kodi on pc is indeed experiencing mini stutters, while my kodi on my media box is 100% fluid.
It's frequent but with spaces of it being fluid aswell. So I was doubting my own eyes.
But it just barely annoyed me, sometimes more then others.
Thus I had to be sure and checked.

I check madvr OSD and there don't seem to be dropped/ repeated frames or presentation glitches.
Yet mini sutter is still present.

Im on 430.39

I had heard this was a thing that happend often to RTX 2080?

Can any RTX user tell me how they eliminated this problem?

For now I am just playing the same movie both on my pc and kodi box at the same time.
Trying to play them back at the exact same time for my ambilight to be correctly timed with the video source coming from android kodi box. to still have 4k HDR Ambilight with the video.(which is impossible for the android box alone I have, which is why I would prefer PC now, but mini stutters..)

These settings solve it for most people:

You mean this?
This is NVIDIA Profle Inspector tool with an optimized profile for MPC-HC/BE.

Download

Most important settings it uses:
Power management mode = Adaptive
VSync = on
GSync = off
SLI = off
Prefer NVIDIA on Optimus systems

Already using those ssettings.
Though I dont see a prefer nvidia on optimus setting.

Anyway these settings make 0 difference appearently.

The only option in Kodi to use MADVR with HDR goes through Kodi DSPlayer ???

There is no other?

this is the version where telemetry can create a huge load on the CPU.

Hello everyone.
Occasionally I am experiencing stuttering in moving scenes, but no dropped frames or presentation glitches.
How can I track what is causing this?

I enabled full screen exclusive mode, looks like it is helping a bit but still I see it.
Does FSE still makes sense?

I am using madVR v0.92.17 with latest MPC-HC on Windows 10 64 bit.

430.86 has been working very well for me. 430.53 fixed that bug.

Hey guys on my laptop when I use madvr and MPC-HC some videos (not all of them, but most of the mkv's) became colors washed out in fullscreen. (btw this does not happen on my external monitor)

Washed out colors (or crushed blacks) usually come from a wrong 0-255/16-235 setup.

Check your driver and/or monitor settings.

On your laptop madVR should be set to output full range 0-255, but it only happens in fullscreen? If that was the issue it should not be only when fullscreen. Any more details, like OS, GPU, driver, laptop model, etc?

I'm wondering if there is any disadvantage to using CUVID in the LAV video filter? Is D3D11 better quality? The reaaon I ask is that D3D11 drops lots of frames at default settings in madVR, if I reduce everything I can just about get it working but then I get random artifacts, madVR doesn't report any presentation glitches though. With CUVID everything is perfect even with higher settings in madVR. I also noice huge cpu usage using D3D11 , I get similar results with dxva2 native or copy back to D3D11.

I'm trying to watch 4K HDR content in 3840 × 2160 resolution, 23Hz, RGB Full, 12 bit, using a 6GB Nvidia 1060, CPU is i5 6400, 16 GB of RAM, latest Nvidia drivers, I've tried both the standard LAV filters and the nightly builds. This is on MPC-HC. TV is LG C6.

If there's no negative effect to using CUVID I'll carry on using it, I just can't seem to find the answer searching around.
