I am sure nobody cares about my ignorant FYI inputs as everyone thinks they are purely user-errors, but after I cleanly installed the new Windows 10 Pro x64 Creator's Update, I started seeing many dropped/repeated frames and glitches with settings that always produced none of those issues. This affected only Exclusive Fullscreen mode with ANY settings (including frame-ahead settings) in madVR during playback of normal 1080p 23.976p content on my 1080p HDTV at 23.970Hz for normal 23.976/24p content, but there were no frame drops/repeated or glitches on my 120Hz monitor in Exclusive Fullscreen mode! Window mode (or non-exclusive Fullscreen mode) was not affected.

On my TV at 23.970Hz it would always show "1 dropped/repeated frame every 5-30 seconds" regardless of madVR, ReClock (official or beta), LAV Filters (official or nightly) or MPC-HC x86 (official or nightly) settings. I mean I tried many MANY settings in madVR and ReClock and none did anything helpful, although I noticed that ReClock would always say it is using CINEMA 24p/24Hz adaptation for regular/normal 23.976p content and oddly it detected my 23.970Hz refresh rate as 24.000Hz for hardware display. I don't remember if that was the case before.

I figured that maybe the issue is in refresh rates and I finally fixed this issue for Exclusive Fullscreen by removing 1080p23 entry from madVR as a possible refresh rate (even though my TV shows 23Hz, 24Hz, 29Hz, 30Hz, 59Hz, and 60Hz for possible refresh rates) and leaving 1080p24 at the lowest possible refresh rate to be used for 23p/24p content. Now it says "1 frame drop every 2-3 hours, even at very-high quality GPU-demanding settings). I don't know what this means, but if you suddenly find yourself in a similar situation, see if using 24.000Hz instead of 23.970Hz solves the issue.

Also, NVidia just released new drivers (381.62) with official support for Creator's Update - so maybe something did change in Creator's Update that earlier NVidia drivers (378.92) did not support or worked-well with.

Did you tried 23p without reclock?

Hi to all. Finally Windows 10 Creators Update is out and the new nVidia Driver with WDDM 2.2 are out.
The new driver are 381.65.
But with Kodi + madvr settings for passthrough the HDR metadata don't work.
My tv Samsung KS8000 don't change into HDR mode.

Maybe a new version of madvr can fix this?
Thanks a lot

Yeap and I tried with MPC-HC x64 too, but at 23Hz setting there is constant and consistent frame drop and glitching.

I just used DDU to cleanly get rid of old drivers and installed the new ones - the problem is still there, but I guess I do not mind it since 24.000Hz and 23.970Hz are so close and neither are 23.976Hz, so ReClock is necessary.

With new drivers I also noticed that in some games, I can now only select 59.97Hz refresh rate instead of the usual 60Hz. I think its Creator's Update that messed something up...

HDR metadata pass-through is not supported yet.

Someone on avsforum managed to do that:

Did the Windows 10 and NVIDIA updates, and confirmed HDR working on my B6P via MPC-HC and madVR using HDR passthrough and a 1060 card. The desktop looks like crap - *way* too blue - so the next order of business is hunting down some HDR mode settings.

The problem is that HDR mode is ON or OFF manually by Windows Screen Settings.
If I turn it ON, all content show in HDR mode. Normal video, windows dekstop and all color are washed. But if I disable the HDR mode in windows, all content is show in normal mode.
MADVR is always setup to passthrough HDR content to the display.
The switch from HDR on and off is not automatically.

This just enables HDR output mode, it does however not actually achieve metadata pass-through. madVR is not setup to do that yet.

What does MadVR do with the HDR metadata? I've tried playing back HDR content with the "passthrough option" and it looks really good when the display is in HDR mode, so if MadVR isn't passing it through, what conversion is taking place?

Using passthrough no conversion is taking place but it also doesn't send the metadata, madVR is simply discarding it/not sending it. You would need to manually configure your display to match the metadata, if possible.

Your TV probably uses some default metadata if none is send, which can look OK, but may not be perfect at all times.

So can we expect an update for metadata passthrough and auto switching to HDR/SDR like it does with 3D/2D ?

Hi all,

I want to downscale HEVC 4K UHD content to 1080p with madvr, however the ony way to get acceptable frame render times is to set image downscaling to DXVA2. The madvr algoritmes all give me render times above 40 or 50 ms. My GPU is a GTX1070 so I assume it can do better then this.

My display is a JVC X5000 projector which has native 1080P panel resolution but accepts 4K input (e-shift technology).

Any idea on how to troubleshoot/fix this?

Ronald

Maybe the file is broken or something.

thx I tried that but i couldnt get get it to be smoth. i got it to work with mpcbe in windowed mode. full screeen still dint work. yup its hevc

change the GPU power setting to adaptive in nvidia control panel.

Why downscale when you can send the 4K content as is and make use of the JVC's 4K e-shift? You will get a perceptually higher resolution and better image quality that way.

Thanks, I've done so now, did not make any difference though.

Well the thing is that I disagree (perceptually not in theory ;-) ). I find 1080P output looking better then 4K, it make the image a bit noisy and jittery in my opinion. Besides that, every time a file won't play (not that this happens a lot), windows changes video settings back to 1080p each time which is very very annoying.

Anyway, I found a 4k -> 1080p downscaling configuration now that works:
chroma: superxbr 125 + superres 1
image downscaling: SSIM 1D 100%

Quite happy with the result :-)

Gtx 1080 ti vs gtx 1080 g1 gaming

Hi. Someone who has a gtx 1080 Ti? I have a gtx 1080 g1 gaming. I'm thinking of changing it. The render times are much better?

Well it's like the Titan X, so about 30% faster than your 1080. Yes that translates to render times in madVR too when you use intensive stuff like NNEDI, NGU very high etc. Is 30% enough of an improvement for you considering the price? That's the question.
