Yeah, that's what I noticed too. I'm not sure if it's related to GPU usage or GPU memory use, but any complex algorithms including super-xbr cause my queues to stop filling up despite the processing times being very low. That's on a GTX 1080, so hardly a weak GPU.

does the refreshrate change in FSE? it is clearly running at 59p

Alright, here's after default reset. Don't mind those few drops/repeats shown, they only happened when opening the file and switching to fullscreen, they don't happen during playback.
can you now add NGU sharp for the scaler don't touch anything else.

Yes, turning it on/off makes no difference.
sorry i forgot AMD doesn't support it.

That's the thing. It shouldn't even be 6 ms. Before 1803 and now in FSE, this file plays at around 10-11 ms, which is when everything works right with no drops.
It's like 1803 no longer allows MadVR to use the system at full power.
the ms increase that's more than strange. you are not using 2 screen by any chance?

@Ver Greeneyes

don't use optimal power saving setting in the nvidia control center and the problem should disappear which is sadly the default setting.

All default with NGU Sharp Med
All default with NGU Sharp High

No, just one.

Nah, I've had it set to Adaptive for MPC-HC for ages. This started after the update to 1803.

Adaptive make rendering spikes, if you want no spikes, use prefer maximum performance.

Anyone knows what gives the best details between software decoding and DXVA2 Copyback decoding on LAV filters?

Decoding HEVC ~ 80GB files puts my 8700k CPU at load, even though it's clocked at 5GHz

only dxva2 native has lower image quality and that not a decoding issue so you what ever works best for you.

Obviously DXVA2 Copyback is superior than software if image quality is equal between them, the question is if it is, I heard some people getting more artifacts with DXVA2 copy-back

I'm switching from MPC-HC to MPC-BE, but MPC-BE doesn't seem to want to cut out the black bars the way MPC-HC does. I set up the options between the two to be as identical as possible, and of course madvr's settings are the same between the two.

Is it a known issue that MPC-BE doesn't cooperate well with madvr's black bar features? I did find this old discussion between madshi and someone else on the MPC-BE thread regarding madvr black bar support, but it's kind of over my head in the technical details. Also it's old.

Wasn't sure if I should ask this here or in the MPC-BE thread...

It's working here with BE using the latest beta (always worked).

they are bit identical for codecs like h264 and newer.
i still don't see dxva2 as obviously superior but let'S leave it at this.

How does the smooth motion on/off logic work?

"only if there would be motion judder without it..." - Smooth motion is turned off on VFR video, how can madVR think there won't be judder?
"... or if the display refresh rate is an exact multiple of the movie frame rate" - Isn't this a good example of when SM is *not* needed?

I meant that it's superior since it doesn't consume massive amounts of CPU when decoding large HEVC files. This is assuming MadVR doesn't hog 99% of the GPU already, but I doubt it requires more than 5% GPU power on my 1080 TI with DXVA2 Copy-back.

IIRC DXVA is done on a separate chip (or a dedicated section of logic on the main chip) so it shouldn't use the rest of the GPU (except for copying data back and forth).

Are you sure that's madVR causing the delay?
It seems like it may be either Windows SmartScreen checking, or your media player (perhaps version or other telemetry checking).
The last time I checked madVR doesn't attempt any network connection unless you have the LAN option set (which isn't impacted by internet connectivity).

Isn't madVR using a network connection to send crash reports which is the telemetry of your system?

Only if it crashes and only if you actually press the Send button. This would not interact with playback at all.

The madVR options thread should have the answers to your questions.
