Let me ask again
In target peak nits(tone map HDR...)we put display's peak nits or the calibrated one if there is?

There's probably going to be some debate on this one. LOL Some people are using very complex sets of rules to change the target peak nit based on the content. The general idea is that the target peak nits is what your display can actually display. If you've calibrated your peak nits on the display then you should probably use that. Anything above the target will be tone mapped.

Is there a debug OSD for madTPG (similar to Ctrl+J for madVR) or on option to dump some detailed log to a file? I would like to check the output bit-depth in exclusive mode (while using madTPG with CalMAN).

Around 40 is too high to avoid frame drops in my experience, I keep under 38ms as a rule for 24fps. Drop back a touch one other setting and you should be fine.

Yes but my point was that there was no frame drops. "Only" a few stutters here and there (much like stutter in games). Btw the average render stats is just fine. I was just wondering why the max stats jump so high up from the average.

Simplest answer is:

If you are using "Output video in HDR format" target value should be slightly below point in which your display enables tonemapping

If not, then use value as high as possible that doesn't dim the image to much to your liking.

Cut back on some settings and see if it still does it, first step in troubleshooting is to narrow things down. Wouldn't hurt to monitor the GPU as well.

Hi Guys,
I own a win 10 htpc with nvidia gtx 970. Latest lav filters and madvr.
I've perfect playback with uhd hdr@24fps files.

With uhd hdr@60fps files it is massively not fluid.

I've set madvr to call 2160p60 resolution when a 60fps playback starts.

I also activated a roule to lower madvr scaling and rendering filters.

Attached the settings.

Rendering times is very low but the reproduction is still not fluid.

Any idea?

Thank u all

a 970 doesn't have a HEVC decoder it may be barely able to do 24 with is very bad hybrd "decoder" but that's not a great result and please don't disabled dithering.

there is nothing supposed to change that counts for every program at least if it get's restarted.

Just an FYI to NVIDIA users - I got frustrated at the state of NVIDIA drivers lately - I have a Geforce 1080, and I wanted to use a driver that is reasonably new, but still be able to play some games. I settled on the 399.24 drivers, but had one massive roadblock: I am unable to create a 23.976 hz custom resolution. The 399.24 driver "helpfully" tweaked the default resolution settings to get closer to 23.976, but it ends up being 23.9774 or so as reported by MadVR, on my Sony 1080p projector (HW40). This means a frame repeat every 20 minutes or so. Unacceptable, as I was able to achieve 23.97617 by decreasing the total vertical pixel to 1124 instead of the default 1125, which I cannot do anymore with 399.24!

Then I read a post in the CRU thread ( https://www.monitortests.com/forum/T...ty-CRU?page=70 ) that he created 48 hz resolutions.

So I decided to try it and it worked - I can get 47.9517 hz, which is very good. Nearly exactly double 23.976! I hope that those of you with the same problem can try this on their displays - with luck it will be supported!

Screenshot of my NVIDIA Custom Resolution dialog box:
https://i.imgur.com/Ik78bgt.png

There is one caveat though - MadVR doesn't know to switch to 1080p24 when presented with video that is 24.000hz. It always selects my new 47.952 hz resolution! Madshi, any way to fix this?

If not, a workaround would be to just manually change MadVR's display mode string and restart the player, or create a program to check the source framerate and switch to an alternative MadVR configuration before the player is launched.

Is there a way to stop madVR from drawing new frames when paused?
I tend to keep many players open, and the GPU/CPU usage starts to add up significantly. It's an issue on laptops, especially.

Thanks

Make an empty folder called "DontRenderAfterStop" in the madVR directory.

However it doesn't stop forever, so it may not work for your use case.

Did you capture that screenshot of the madVR OSD with the video paused? It looks like it was and we need to see the unpaused OSD to give useful advice.

Also, make sure Focus Assist is completely off, all the options in the focus assist settings page should be off.

Are the cheaper NUCs with Radeon 540s (2GB) any good for madVR NGU? Specifically the BOXNUC8I3CYSM1 w/ Core i3-8121U.

FSE mode seems to be acting a little finicky on my monitor. It either doesn't enter FSE or enters it without the problem that I posted about (black bars on the side squishing the image horizontally), which is good. The issue may be file-type/encoding specific. I'll be sure to take a scrnshot of the OSD when I see the problem again. Although I don't think scrnshots work on FSE mode. I probably have to take a picture using my phone. Thank you for your reply.

On the first pic in OSD: you play 60.00Hz content on 59.94Hz! That's why you get drops

What exact values do you have in madVR for display resolutions switching?

Not if you are upscaling to 4K and not in general. NGU is a neural network scaler that requires a lot of processing power. It is much better suited for a gaming GPU.

Hi, i've been experimenting with my ATI RX 580 (can be bought for as little as £125 now ) to see how far I can push it to keep it under 60 degress and therefore have my fan stay at zero RPM's. I'm finding that I can generally use NGU sharp medium for upscale and chroma and still stay under 60 degrees for all material, if I use NGU high it can pop over the top now oand again so i'm probably going to stick with medium.

My question is, all my material is now 1080p or higher, is there any genuinely noticeable differences to the eye when deploying high quality scaling / choma with this higher quality material, I just cant see any difference at all between high or low for 1080p/4k stuff.
