My theory is that AMD tries to do the smart thing and dynamically pick the metadata (Rec2020, DCI-P3, Rec709, etc) to be sent to the display (in HDR mode), so that the display's built-in processor becomes responsible for any kind of gamut mapping if necessary (from the color space indicated in the metadata to the native display panel colors) which eliminates all the potential performance overhead and/or quality degradation on the PC's CPU/GPU side (the original default behavior since Windows 10 1703 seems to be a conversion of the SDR Windows GUI and all SDR application window's content to Rec2020 [from Rec709] and constantly feeding the HDR mode display with Rec2020 colors whenever Windows is set to HDR desktop mode --- in the early days this clogged the CPU, then it started punishing the GPU with notable performance and quality loss [think about video games when considering the performance] --- now it might becomes a job of the display's processor which is theoretically the ideal choice in all respects). But it looks like it doesn't always work as expected (the display might gets Rec2020 colors with Rec709 metadata, or vice versa with gamut mapping might or might not happening on the PC's side). But it could also be a random bug. I am not sure if Microsoft and/or AMD really trusts the displays to handle this properly (for example, my LG TV seems to handle these kind of metadata changes without blinking into black screens and such but others might not and need to re-initialize).

if it was an AMD problem wouldnt that show in MADVR and in the windows "film and TV" player,? there only seems to be an issue with MADVR playback.

Yep, I know I'm gonna get a whole lot of pain on this one...gone back to madVR09209.zip....to my eyes, in a real life environment, nnedi3 wins hands down over NGU.

Yep, gonna get flamed, I know.

Ryzen 3 2200G with Vega8 iGPU.
Samsung UE40NU7100.
Top one is MPC-BE with HDRF to SDR conversion, below are MADVR and Windows 10 film and TV player, all three looked identical, ignore the reddish tint to these, thats just my camera, in person all three looked spot on.

Which NGU did you compare it to? NGU AA looks very similar to NNEDI3 to me in a "real life environment" (what do you mean by that?).

yes my sig is accurate, i'm not using MADVR .17 as i had issues with 3D with it which I reported to MADSHI as a bug, i havent tested that version for a while though so I might give it another go at some point, I was just going to wait for v 1.0 though.

I must admit, never really tried AA. only standard and sharp (on 1080p material), but NEDDI3 just seems more natural, and seems to bring out different details (to be expected).

Will take a closer look at AA though.

50fps issue

I have an issue with one movie (ripped Blu-ray in 1080p), the source material is 50fps.

I have no idea why all other videos are working fine (typical 24fps look great, and no dropped frames), but I struggle with 50fps, the video seems choppy, every sec I am loosing over 15 frames.

I tried to tinker with all settings and display modes, but I must have overseen something.

Can you please help, I have a good machine, so hardware is not an issue, and the video is similarly choppy with Cubic and NHU very sharp?

Can someone please help me ensure my 4K HDR settings are right for my LG C9 OLED TV?

- Do I want the drivers and the TV both set to "HDMI RGB Full"?

- Do I need to manually enable 24hz 12bit in NVIDIA drivers prior to watching HDR content? This setting seems to revert to 8bit whenever I swap back to 60hz 8bit and restart the computer. Maybe I need to make a bat file or something to make this switch automatically when I launch Kodi?

- Do I want to select 24hz or 23hz in the NVIDIA drivers?

Thanks.

Non-UHD Blu-ray doesn't support 50p, can you confirm the source is 50i? If so, are you using software or hardware deinterlacing?
If it's really a movie it should be 25 fps, not 50. Are you sure it's not a video like a documentary or TV studio programme? If not, check if some setting is not forcing deinterlacing and creating 50 fps out of your movie.
50 fps puts 2x more stress on the GPU for rendering so if not using profiles it's possible your settings are fine with 24p but not with 50i/p.
Post a screenshot of madVR's OSD during playback to some external image hosting site so people can find out what's wrong.

Hello, yes I can confirm, its Blu Ray TV series (PAL,in 50fps thats what madvr OSD says). On the other hand I checked the file properties manually I got this info
Video: H.264/AVC 1920x1080 25fps [V: h264 high L4.1, yuv420p, 1920x1080]

And you are right it looks like GPU (2070 Super) is doing twice the job.

Thanks for help

I have a LG 32UD99-W monitor which is supposedly HDR. Could you please tell me what settings in madVR I should choose?

in hdr if I set to let madvr decide or passthrough HDR to display, my monitor goes to black and only restarting my PC I can have the monitor back.

For the moment I use Tone map HDR using pixel shaders. What are the best settings for this HDR monitor?

@Harumi did you pause playback before taking the screenshot? You have to take it without pausing to get really precise stats for the queues, but it's already showing 27 ms avg render time which is too much indeed.
It says the source is 50 fps so it's probably being deinterlaced in the decoder filter.
Do you maybe have any other processing options active (enhancements/artifact removal/scaling refinement? If yes then disabling some can help.

What are these suppose to be for 4K BD HDR content on an LG OLED? https://i.imgur.com/JXe5UeH.png

I can select 4k24hz 12bit RGB or 4k60hz 10bit/12bit YcBCr422. However, they don't stick when I switch back to 4k60hz 8bit RGB and restart the computer. So I am unsure how this will even work without adjusting the setting depending on what i'm doing?

If I just use NVIDIA default, it seems to only use 8bit RGB full: https://i.imgur.com/gYFBIUA.png

I'm having stuttering issues with Direct3D 11. The motion is much smoother with DX9. Strangely, enabling Error Diffusion with DX11 makes the stuttering unbearable. If I use DX9 there's no problem but I'm losing 10-bit output for HDR, right?

2080 Super, 436.30 drivers, latest madVR and MPC-HC with LAV Filters.

Will take a closer look at AA though.
Please do, it really is very different than the other NGUs and closely matches the look of NEDDI3. It is the odd one out of the NGUs, it does not share the same look as the NGU sharp/standard/soft family. It even shares that slight pixel shift with NEDDI3 which the other NGUs lack. When NGU was being developed it was NGU AA that allowed us to fairly unanimously agree that NEDDI3 was no longer needed.

I have been a big fan of NEDDI3 since it was only available in Avisynth and even 64 neurons rendered way less than real time on my CPU. I now use NGU AA by default. Some content really benefits from NGU sharp but usually NGU AA or NEDDI3 seem more natural to me too.
