Not a significant change, perhaps 0.5 ms slower for average rendering times with 4K HDR.

Control vs DLSS 2.0: Can 540p Match 1080p Image Quality?
https://www.youtube.com/watch?v=YWIKzRhYZm4&t=309s Why does it not work in movies ? Is it possible to open it in a driver ? |

Isn't that how NGU Sharp works?
The difference being DLSS uses the dedicated tensor cores to do it, and NGU Sharp doesn't have those artifacts on edges seen in that video (I don't know if it comes from the use of lower precision tensor cores, of from NGU using much more processing power to do the work, probably a bit of both). There are users of madVR that force doubling using NGU Sharp then use a sharp downscaler even when displaying at the same definition as the source video, to achieve sharpening.

For movies we need a generic solution that is trained on a variety of movies and all that madshi has to feed it was 4K source material. |

But either way, DLSS itself is trained for sharp video game footage, not video. We already have neural network based video upscalers though, that concept is not a new one. NNEDI3 is a popular one. And I believe NGU in madVR also uses that concept, and many others.

just look at the images it really bad (in incontrol) the reason people like it is that it is sharper the huge artefacts are just ignored. you could simply run a sharpener that doesn't ring like that and get an better results which may be slower.
madshi has already confirmed that NGU is currently retrained and 16 bit will be used too. and that's done using tensor cores nvidia RTX cards. |

So, unless you measure and tune it yourself, not knowing is still a problem. 4K hdr content is ALWAYS better than 1080p sdr content. We're not at the point where producing 4K discs is so cheap that poorly made garbage is getting though. As for tone mapping, Madvr makes assumptions, and it assumes whatever value you give it. But that value is not truly meaningful unless the monitor is calibrated or profiled (3dlut). luckily madvr's hdr will still look pretty decent without any of that. The one thing that you might be missing out on is proper 2.2 gamma. The majority of monitors out there have botched gamma curves out of the box.

Thanks. I thought that DV metadata is encoded in a manner of HDR10 metadata (except the case, when there is a separate video stream used to encode luma data), so it can just be passed through, and the monitor will deal with it (my monitor supports DV profile, and I'm able to run it in DV mode in Battlefield 1 and Mass Effect Andromeda, but with DV I have to use DV LL decoder in the form of Dolby Vision Extensions for Movies and TV app on Windows 10, which is not quite convenient).

Ok, so I am nuts and back at another attempt to pass through HDR to my projector, and see if I can get it set right to where I don't NEED tone mapping.
Running into a 'black crush' wall.. I set my Nvidia to RGB Full, MadVR to Limited, and PJ to limited. I then selected Pass through HDR to Display, and checked send metadata. When I have metadata checked, the display automatically converts to HDR (and shows as HDR in the PJ settings). However, my black levels are crushed. When I use the black level video (http://aaa-computerrepair.com/zip/02...k-level-v2.mp4) - I see NONE of the numbers - so totally crushed... (and no wonder I have felt that HDR seems 'dim'!!) When I switch OFF the 'send metadata' - the projector does NOT show as being in BT.2020 or HDR. I can force the setting to HDR10 in the projector settings (which does look good on the PJ) - but the PJ is still not automatically registering that it is in BT.2020.... Also, regardless of the metadata setting, MadVR shows that it is outputting in DCI-P3 (HDR 1000 nits BT.2020 -> DCI-P3) - why is this? Can I have MadVR output in BT.2020 directly? Maybe that would help my issue? I am totally confused - any help is greatly appreciated!!! |

Edit:
I have my Nvidia output set to RGB Full 12Bit. So even though it isn't telling the projector it is HDR, it is still showing D3D11 10bit fullscreen windowed as the output. So it has the 'full' bit depth that it should natively. Windows still shows output as SDR though when I check the display settings. Anyway, when I FORCE select HDR10 on my projector - the picture comes alive... it looks GREAT. And I am down to 14ms frame timings since I am not doing all the HDR to SDR processing. Have I found a 'loophole' for tone mapping? E.g. am I getting 'free' tone mapping through my projector? Or something similar? |

1000 nits, not 10,000. For example, my HDR device does 1500+ nits so passthrough is acceptable vs tone mapped imo. I think the -> DCI-P3 is referring to what the source was mastered in, not what it's outputting which is BT.2020.

Guys, I'm having trouble setting my MadVR for 4k60 Videos from Next Gen Games. I watch them on a 1440P monitor using SSIM 1D Downscale.
My 5700 has a special Profile for 4k60, but I'm Getting 19ms and Dropping Frames. Which one should I drop first? "Chroma Upscaling from NGU High Quality to Medium Quality" or "Image Upscaling - Doubling - NGU Anti-Alising Medium"? What is the most important one to be higher? Other suggestions? Thanks! |

I don't know much about games but as a rule of thumb, 4k doesn't need to be image upscaled because it's already at the highest scale but it could benefit from chroma upscale. So, if you're running out of resources with a 4k video, lower luma. Once you do, you might even be able to raise chroma a bit. Fwiw, on the flip side luma becomes more important than chroma when using lesser resolution video you want upscaled to your native display resolution such as 2160p. I don't know much about 1440p and how gamers flip flop resolutions around though.
