I still think matching refresh rates is the "correct" way to do it. Smooth motion is completely an acquired taste. I don't like it. Others do.

And always use madVR's upscaling if possible. Do your think your OLED has the processing horsepower of a gaming GPU? That's what madVR's scaling algorithms are all about.

it's unlikely that anyone will spot the difference at 120 hz.
if it is working correctly it's not visible.

and VFR is not really possible to frame match in any case.

Yes, I missed the variable frame rate part.

in a perfect world with working TV and no VFR content SM would be only useful for PC screens.

just as a small reminder if SM is more smooth than frame matching you simply have one of the countless TVs that can't frame rate match to 24p and with that it is unable to present the creators intend.

thanks for the input.
now after disabling DSR, they works, even got a perfectly optimized status for 23. i use latest whql driver (created with madvr too, not nvidia cp)

though i must add another question, if i change my audio output (from direct audio jack from pc to monitor's jack) is it normal that the frame drops/repeat got worst and i need to make another optimization again?

depends.

if the monitor takes the audio signal from HDMI yes it has a different clock.

With 4k@60hz, SM seems to work very well with everything I've thrown at it. I don't think I see any noticeable blurring. I don't think I can really notice a difference in smoothness vs frame matching, and now the resolution/refresh doesn't need to switch back and forth for every video.

1080p@120hz seemed to be matching perfectly for my VFR stuff. 23.976 an 29.97 both fit into this evenly, or am I thinking about this wrong? I actually had to set it to 119hz in madvr (for 119.88) to get it perfect, i guess similar to setting 23hz for 23.976.

But madVR upscaling everything to 4k seems to be a lot better PQ than letting the TV do it, so I think I'll stick with SM until 4k@120hz is a thing

There's quite a difference between concatenating the pre-built ICC A2B and B2A tables and then crunching the pixels with the resulting link, vs. creating the B2A table by inverting the A2B with any accuracy and/or computing a sophisticate gamut mapping.

And it would be pretty ludicrous to say that professional image editing software like Photoshop do this in subpar quality. In fact people using Photoshop probably care even more about color accuracy than videophiles.
Yes and no. Photoshop takes a great deal of care in applying ICC profiles, but has nothing to do with the accuracy of the profiles themselves. It just uses the ICC tables. For instance, it doesn't try and improve on the accuracy of the A2B and B2A tables re-computing B2A lookup or computing profile pair specific gamut mappings in the manner than collink is capable of.

As for "3DLUTs are not just slow for fun", well, it might be that programs like ArgyllCMS's collink command are slow because there is no perceived need to make them fast: people use it offline and very infrequently, no one cares a great deal about how long it takes.
Oh boy - I think if I added it all up, I've spent years of my time working on the performance of elements that make up collink, from profile inversion to gamut mapping. There's no doubt that there are faster ways of doing less complex gamut mapping or lower accuracy profile inversion, and of course there are almost certainly speedups possible to my current code, but its not slow for want of caring nor effort.
Quote:
I suspect it would be possible to do it much faster with little loss in quality if one were to specifically optimize for that. (Does anyone know how long LittleCMS takes to generate a transform?)
Go right ahead - optimize away!

Note that collink will link profiles in simple mode in comparably short times to lcms and Photoshop though.

Hello everyone , I found a very strange thing on MADVR with windows 10.
Today I update my windows 10 which is on the latest stable version (creators update) into the insider on slow ring which the version is 17115. (will be spring creator update release in this april)
Madvr works no problem, but the rendering time reduces a lot on my GTX1060!! I can not believe it ! 720p=>1440p on luma GPU sharp very high and chroma ngu aa medium only 6ms!!

https://imgur.com/a/1cgjc

I think it is at least two times faster on my GTX1060. How is this possible! is it a bug or the new windows 10 do some magic?

try advanced randersteps.
my 1060 needs about 18 ms at 1760 mhz for 720 -> 1440edit: using NGU sharp very high, doubling chroma NGU mid.

What is advanced randersteps?
My 1060 need 18ms too with creators update and I didn't do any overclock.

create an empty folder with ShowRenderSteps in the madVR folder.

pascal GPU are changing there clock like they have nothing better todo that'S why i add the mhz.

Thanks, here shows the result

The GPU clock i viewed in GPU-Z is in the range with 1760-1835 almost at 1797

you could do with setting up refresh rate matching as you're getting frame repeats every few mins?

he is using SM why should he waste his time with that?

are you using adaptive power settings? 1760+ mhz for 8 ms and lowerwhich should be less than 20 % GPU load.
my guesses right now are wrong rendertimes or madVr thinks or is debugged and is not using NGU i mean it's a win 10 insider build so you know...

I havent got into SM to be honest, not really sure what its for but I thought it was deployed only where there were issues with matching frame rates. When I've tried it in the past its never been perfect, i'd always see a jump or a glitch here and there even if general playback seemed smoother, I find matching frame rates gives the best playback for me.

not much but I was using an 8gb RX480 when I last tried.
