madVR - high quality video renderer (GPU assisted)

I'm using a Samsung older non-smart TV on a 1070 via HDMI with audio. But it really doesn't matter where i fullscreen exclusive or windowed (on any of my 4 monitors), the behavior remains the same while putting out audio through the TV with madVR on exclusive. I've tried switching audio renderers, and i think the non-direct sound is slightly better, but i'd need some testing video clip to scrub through frame by frame to figure it out exactly.

Are you bit-streaming or decoding on the PC? Either way, this sounds odd. The only time I deal with audio delays is when I use processing on the TV (Real Cinema, I'm looking at you!) :P

[chros]

Which state of Real Cinema? Because it works exactly the opposite way than most think.

The issue is that while in exclusive fullscreen mode (which btw, the 3 second delay setting does nothing), i have a measure of audio lag/desync which stays consistent, and is not stuttery or anything, just always a step behind the video. Not really sure how much but feels like 100-200 ms. Also, not using exclusive creates some random video jutter which i'd rather avoid. Any idea where to start looking?

Any reason why you're running a present queue of 14? That is really big. This is Windows 7? Have you tried D3D11 presentation just to check if it changes anything?
I assume you took this photo while playback was paused? Could you take another one while the meda is playing?

@chros - Real Cinema ON, which then does a 5:5 pull down, adds a huge delay to the video. I can only speak to how it works when going through a receiver, though, and of course also only when it comes to my LG C7. In addition to Real Cinema, playback at 24Hz also adds a delay compared to 60Hz. Audio delay drives me nuts, and that's actually the reason I am now back at 60Hz with smooth motion: no noticeable delay.

Did a fair bit of research when i set this all up so i'm sure it was for a good reason but i can't tell you what that was for the life of me. Lowered it down to 12. W7, yes, no aero and desktop compositing off, but tried turning all of that on and setting it up from madVR and it still defaults to D3D9.

https://streamable.com/6vfcuq << vid, exclusive mode, excuse the phone but setting up obs and stuff i think would'ave interfered with the process. You can notice the audio delay there. (i have to admit that hearing that line 'my mother named me Enola' with the punchy enunciation on Enola clearly marking the word was was triggered me to solve this since it was so visible)

For comparison, this is with it in non-exclusive mode https://streamable.com/l3emvd There is definitely a difference in sync clearly visible when objectively recording. Which also drops frames constantly and delays, which is what i assume the stutters i notice are.

You have to restart kodi to return to normal brightness(windows gui is normal color, no resolution switch happens). With rolling back to 446.14 driver everything works fine. I think I must be nvidia driver issue.

I have exactly the same problem

[dejarik]

I have used Madvr for a while with a TCL 6 and never had
any problems with HDR passthrough but with my new Sony it's
a mess i'm force to use tone mapping, it looks good but i would
prefer using the TV HDR directly is there something i could be doing wrong ? or Madvr simply doesnt support the TV.

[huhn]

what GPU?

[dejarik]

Gtx 1070

[huhn]

try driver 456.38. state the model of the Tv too.

[dejarik]

Driver I'm using are the 452.06
Tv Model is a Sony XBR55X900H

I'm gona test the 456.38 and let you know

[huhn]

HDR generally shouldn't work with that driver.

and i have issues with 456.55 but i had a lot of issues so no need to talk about it.

and you are in luck i know a lot of the xh90

[dejarik]

Seems to have made a difference i dont get the weird artifacts
but HDR doestn seem to be enable correctly picture is washed out

[huhn]

try fullscreen exclusive.

[dejarik]

Did a few test for some raisons tone map hdr using pixel shaders
seems to give better results i have notice that dynamic metadata
is not supported on this Tv don't know if it makes a difference ? i
would think maybe it does

[huhn]

the TV generally doesn't really care about meta data and madVR doesn't support dynamic metadata AFAIK. it just measures it by a frame by frame basic anyway.

this TV doesn't support dolby vison (at all) properly and can't handle it correctly. not to be confused with the dolby vision on UHD BD which is still HDR10.

[dejarik]

Tone map hdr seems to gives a verry decent results, also
i should update the firmware on this Tv i'm waiting for the
hdmi 2.1 and 120 Hz software update, should be release about the same time the ps5 comes out.

thanks for your help huhn
