Finally updated for madVR v0.92.9, new compression artifact removal and screenshot configuration options.

I also added some lower power level versions of my settings.bin file:
--Links out of date, please use the links in the third post--

Heater is the equivalent of my old settings but now I am using a slightly lower power version I called Max Quality here. Feedback would be greatly appreciated, especially for High and Low power. My GPU downclocks when below Max Quality so I doubt the profiles for different resolutions are all at similar power usage.

@Madshi

Is MadVR able to passthrough HLG? I'm implementing HLG support on the older JVCs at the moment (testing with my 2015 rs500) and when I try to play an HLG file I get the same magenta bug as when trying to play 4K60p HDR10 files (as you might remember, I found a workaround for that which is to play 4K60p files without HDR Metadata passthrough checked). That doesn't work with HLG files.

Also the file metadata is changed. For example, when I play this LG demo file: http://4kmedia.org/lg-cymatic-jazz-hdr-hlg-uhd-4k-demo/ from the UB900, the Vertex correctly reports:
HDR BT2020 HLG BT2100 (all metadata to zero) and if I apply an HLG calibration, the picture looks fine.

In case it help, here is the captured HDR metadata in that case: 87:01:1a:5b:03:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00

If I play the same file (or the webm version from youtube), the HTPC sends ST2084 instead of HLG and I get the magenta bug. I tried to disable HDR Metadata passthrough manually in MadVR, that doesn't change anything. Of course the metadata is wrong in both case (ST2084 reported).

Any thoughts? Let me know if you'd like any further info.

HLG is not supported yet. madVR doesn't currently even know if a video is HLG. Also, you're in the wrong thread.

Thanks! wrong thread indeed. Does HLG support need to be added to LAV first? If yes let me know if you need any help with testing.

Once madshi expresses interest on working on HLG, LAV will have to output the information that it is in fact HLG content (unfortunately the value Microsoft defined for that has already been used by madVR for ST2084, so its not as easy as just exporting it already). Fortunately HLG doesn't need any further metadata then that.

Great, thanks, I posted a query in MadVR's thread pointing to this post.

Updated for madVR v0.92.10. Removed NNEDI3 and reduce compression artifacts can be run for free as part of NGU Sharp high (RCA at medium) or very high (RCA at high)!

My low power settings should be a good starting point for a 1060 6GB.

It uses NGU Sharp for image upscaling and NGU AA for chroma upscaling.

No refinements, I only use refinements for specific sources that need it. Some deblocking for SD profiles.

I just updated them for madVR v0.92.10 so get the new one(s) if you downloaded it a few minutes ago.

low power profile

Hi

just tested low power profile with a standard blu-ray.

GPU usage : 30%.

That seems good for a 1080p display, 1080p is much easier so you might be able to use Max Quality.

try outs

I tried these :

Chroma upscaling :

NGU Sharp High Quality

image downscaling :

SSIM 1D 100 ( scale un LL check AR filter : relaxed)

Image doubling :

NGU Sharp -> luma : high CHroma : high

Doubling : always , supersampling


And thats it ( 60% GPU) 1080p60

Are those correct?

I'm just discovering madvr in depth.i'm not familiar with it


PS : you guys dont use upscale refinements? why not? aren't those any good?

I wouldn't recommend super sampling for no reason.

Chroma Upscaling:
I use NGU AA high

Image Doubling:
I use 2x and 4x so it would only run for 540p and below on a 1080p screen. I can also see using down to 1.2x (let madVR decide) but super sampling is rarely useful and actually causes harm.

Upscaling Refinements:
Using super sampling to allow sharpening at higher resolutions before downscaling again is the one time I like super sampling. I only use these for specific sources. Some sources I don't use any, some I sharpen, and some I use soften edges. There are none I would use all the time. Feel free to set one if you like it but do not use too many at once and remember, often "less is more". An good alternative without super sampling is to use image enhancements instead, it offers the same shaders but run at native resolution for a stronger effect.

madvr

Thanks

i was under the impression that it was more efficient tu sharpen an image once upscaled before downscale. In the case of 1080p on a 1080p projector, it means doubling. or supersampling?

What is the difference anyway?

Super sampling (in madVR) simply means the output resolution is the same as the input resolution. Doubling is more general, anytime the resolution is doubled before down or upscaling to the output resolution.

In the calibration tab it says one 3dlut to cover all gamuts is fine. I have a bt2020 3dlut so is it ok to use that for all? I notice reds look slightly darker with this vs a rec709 3dlut when playing bluray
