Hm I didn't mess with power saving options so unless it is changed by default upon the update I doubt it has something to do with it, and temperature should be somewhat the same as before too

Yeah, but is the problem with FSE or with Creator's Update or with ReClock? madVR FSE worked perfectly fine before Creator's Update.

For now I am sticking to just using 24.000Hz mode for my TV - that way I can enjoy FSE's 10bit+ color depth.

Has madshi looked into it? I already reported it on ReClock forums and some members there confirmed the existence of this issue. It is specific to Creator's Update, not pre-Creator's Update Windows 10.

HDR question: I'm playing a HDR BT2020 video and my TV support HDR . In madvr settings I selected HDR passthrough, obviously when I started the video I manually changed TV mode from normal Cinema to HDR video.
When it's playing video info (crtl+J) show

"hdr 1000 nits bt2020 -> dci-p3"

Is it normal/correct? Why "->DCI-P3"?

Thanks!

[sneaker_ger]

It's normal.

HDR 4000 nits, BT.2020 -> DCI-P3

Why DCI-P3 and not BT.2020?

This is for all HDR videos

Yes. The "-> DCI-P3" is the metadata information that tells us how the studio monitor was calibrated when the movie was graded. It usually also tells us how large a gamut the movie is really using. Almost all movies today use DCI-P3. It's not a surprise because masters for movie theaters also use DCI-P3.

Noob question, what is this KNLMeansCL? i read about it but i did not understand, i can't use it with madvr?

KNLMeansCL is GPU-based denoising filter for Avisynth/Vapoursynth. Until madVR has no it's own AVS/VS interface, you can use AVS filters via inserting ffdshow_raw filter in DirectShow filter chain.
Seems easiest way to play with AVS filters is to install SVP, check that it's working, then disable it and paste own Avisynth script in ffdshow_raw settings.

Hello all,

Thought I would post here. Since I went to the creators update for some reasons files encoded in Hi10p (10bit color) are taking a tremendous amount of GPU power in madVR. If I play a normal 8bit file using NGU AA high on both chroma/image upscaling it uses about 25% of my GPU (1080Ti), but a HI10P files will max it at 100% and drop frames. It wasn't like that before the update! I have no idea what's going on =) Just wondering if anybody else has tested this? I wonder if it has to do with the move to WDDM 1.3.

As a side note its only when I go into full screen on the HI10p files (not FSE). If I play the Hi10p and 8 bit in the same size of window GPU usage is 100% same - but when I maximize the HI10P GPU usage goes ballistic. It didn't do that before. I can make the HI10P window the size of my screen and my GPU usage stays low ,but the second I double click it to maximize it GPU usage is through the roof with dropped frames

The power saving option does change by default when the driver updates, which I think happens when Windows updates itself. I have to set it back to adaptive every time a new driver comes out.

Thanks, I just checked and it did changed upon update so I turned off all power saving options but then the problem is still there and is even worse, it does seem like the problem I have is similar to the post above your reply though, anyone else start to have issues after the creator update?

Option "Enhance detail" is on two sides: Processing>Image enhancements>Enhance detail and Scaling algorithms>Upscaling refinement>Enhance detail.

What is the difference between the two options? Which one is better to use?

My apologies if I'm wrong but I think CalMAN 5.x have the option to calibrate bt2020 (hdr and sdr) and also dolby vision (rs65 and rs120) colorspace.

Image enhancements happen before scaling, upscaling refinement happens after.

Before is stronger but after looks better, in my opinion, though there isn't an objectively better one to use. You can use both at the same time too, if you want really a lot of sharpening.

Just as he imagined. To me in some cases looks better before and in others looks better after. I have not tried both at the same time. I'm trying out my new video card Gigabyte 1080 ti Aorus X ... it's amazing the performance I get ... much better than with my gtx 1080 g1.

I am using a HDMI extender between my HTPC and Projector that is capable of 2160p but max 30 Hz.

Therefore I would like to send 1080p 50/60 fps content in 1080p resolution to my prjector instead of upscaling to 2160p.

Resolution of windows is set to 3840x2160@30Hz

the display properties in madvr to:
2160p23, 2160p24, 2160p25, 2160p29, 2160p30, 1080p50, 1080p60

It works, Madvr sends 1080p @ 50/60 fps content in 1080p 50/60 Hz to my projector, HOWEVER I do see only a quarter of what should be displayed. Seems like the image is still upscaled to 2160p and only a quarter of it is displayed on the projector.

How can I avoid this?

Thanks Ronald

this is maybe the windows 10 internal scaling.

the only way i know to disable it is to set " change the size of text, apps..." to 100%.
maybe fullscreen exclusive mode helps.

this is a guess changing the resolution on windows 10 got quite tricky...

Yeah, Creator's Update messed something up or changed the way things worked before... I hope madVR developer is looking into it - I am more than willing to test or provide as much info as.possible to debug this problem.

Try disabling the Windows 10 Game bar. I'm not experiencing such slowdowns myself.

I got a related question for you guys :

I also watch HDR clips thru MadVR using passthruHDR and it look very good on my JVC HDR projector.

that is for all clips that are "hdr 1000 nits bt2020 -> dci-p3"

but I got a couple of dolby Vision Clips that show :
"hdr 10000 nits bt2020" with no dci-p3 conversion info

now those clips end up with oversaturated color and a greenish tint to it.

What bugs me is that I will have expected the oposite to work since on my projector settings the color space in HDR is BT2020.

For now I will try to make a custom HDR settings on my projector and manually ajust the color to try and get something good, but I wonder what am I missing here?

[tingtong5]

Thanks, but I am running windows 7, not 10. also I am already using exclusive mode.

From what I can tell there is HDR10, Dolby Vision and HLG. Which standards do the nVidia/Microsoft APIs support? Will we need to be careful when shopping for TVs? Does it even matter?

Im in the dark, whats so cool about HDR10? why didnt they have the wide gamut before? I thought HDR was something that looked fake, why would we want that?

NGU Sharp now targets middle ground between gamma and linear light

Im curious about this one, stupid question, if some studios use linear light to downscale, is there no way for us to know somehow?



I think im also getting an error "madvr report: getting display mode failed" This could be because of the creators update. It happens when I raise the volume inside exclusive mode, the movie stutters and it becomes impossible to play anything again unless i restart the PC.
