"Latest" as in 113 beta? Your HDR settings are to much for your GPU, you need to pick options that are faster.

I wouldn't have expected it to be a decoding issue, your decoding queue is full. Is your PCIe slot a x16 3.0 one?

Are you sure changing to native did not change the way HDR is being handled? You do need copy back to be able to run all the HDR tone mapping features so I suspect the improvement came from not being able to run those anymore, rather than an actual performance improvement from running native.

it'S not a decoding issue it could be a copy issue but AFAIK DXVA2 native is blocking some of the processing which makes it easier to process and did i already said it should never be used.

Use d3d11 native instead, it's witbout drawback and slightly faster as well.
But it's shocking that a 1080ti has problems with this.
What display do you have?

It's not decoding but processing issue with these cards/drivers and using high bitrate hevc content. Just take a look at the above link, only the 2 native ones are the really fast ones.
It's like copyback modes restricts the whole processing using system memory and who knows how madvr delas with data internally. If someone knows more about it...

What interesting is that there wasn't big differences using Optimus with h264 remuxes, and there cropping helped with copyback processing. So it depends on the given system how it works, it needs to be checked individually.

??? What do you mean? Tons of people use d3d11 native, madshi never mentioned anything like this either.
Also note that in the above test only (!) chroma upscaling was applied, using hdr passthrough.

d3d11 is currently the most limited decoder compared to DXVA2 native deinterlancing doesn't work because madshi didn't implement it it can do it just fine on nvidia at least.

with both native decoder blackbar detection doesn't work which is kinda a big deal for PJ user. measure files don't work or something like that there was some HDR stuff can't remember and i don't know if they still exists stuff changed a lot measure files are not important anymore anyway. there are more features but what ever.

and that's the problem with D3D11 pretty much everytime someone just goes and says use D3D11 native is the best to someone and that "someone" comes a couple of days back and ask why blackbar detection doesn't work anymore or why deinterlancing looks like a freak show.

if blackbar detection and deint are fixed with it it pretty much worth a general recommendation where the stuff that doesn't work with it is external programs and they usually say the user this is the case so everything is fine.

now the big issue with d3d11 and copyback the difference can be absolutely nothing to day night.

i tested 3 PC intensify with it and the conclusion is there is none only that D3D11 will never create performance problems but copyback/software can be an absolutely disaster. i now have a setup with 7 ms just for the copyback if not more all the time with the same GPU in another system with little to zero difference.

there is no reason for this RAM is bored by this the PCIe interface is bored by this and a GPU should be totally bored by upload too that there freaking job that's where they get there textures for gaming so at least software shouldn't make any problems but it does.

that's why copyback is the only sane recommendation you can't recommend a mode where basic feature don't work these question are ask in the first place because the user can't work around these issues.

The main drawbacks for D3D11 native are the lack of black bars detection and the lack of support for UHD BD Menus in jRiver, as both need copyback.

From a performance point of view, native is significantly faster though, at least here, so I enabled it (automatically in my batch file) when I measure my HDR files, but I reselect copyback (automatically) for playback, due to the above.

If you don't need black bars detection and UHD BD Menus in jRiver, it might be safe to use D3D11 for playback, but it's not recommended unless you're desperate due to some features being unsupported.

I have a 1080ti and it has no problem handling everything in high (at 23-30p, at 50-60p it needs lower settings) in copyback. That's with black bars detection, 3D LUT, and 1.78 content in HDR such as Pacific Rim.

So if anyone can't get 23p to work in copyback with a 1080ti and a comparable rig (see my config in my sig), there is most likely something wrong in their settings.

Thank you i just looked up my board Asus z390 extreme pro 4 and it has 3 pci slots it would appear I am using the slowest lane on the board would never had known had you not mentioned it thank you : )

I have my TV set to 23(.976)Hz since most of the content I have is that. I added 1080p23, 1080p59 in the settings for display modes. Intel HD Graphics 5500, Windows 7, MPC-HC.

Whenever I play a video with a 29.97 or 59.94 FPS and then play another video with 23.976 FPS, the video stutters and presentation glitches go up fast. The composition rate under stats matches the first video at 29.97 or 59.94. Setting the refresh rate to 59Hz or 60Hz has the same effect with the composition rate not matching. Is there any fix to this, or is this just a bug? Plex doesn't have this issue.

use overlay rendering that's avoiding this bug.

Nvidia driver 445.75 has broken HDR playback for me.

Anytime an UI element of Potplayer or MPC-HC comes up, playback is switched to SDR and after the UI element is gone it's switched back to HDR. It is very frustrating.

Going back to driver 442.74 has solved the issue.

Anyone else experiencing the same?

I have the same broken HDR issue on Nvidia driver 445.75.
There is Nvidia Hotfix driver 445.78 recently released but I'm going to wait for the next official release.

HDR works properly for me with 445.75 using Zoom Player. Even if I switch to windowed mode (50% scaling) or bring up UI elements HDR stays enabled, though I have to open in full screen or HDR does not turn on.

Good to see i'm not alone

442.74 is perfect. Hope they can correct this for the next version.

How strange, I double checked and I really am using 445.75, Windows 1909 build 18363.752.

Edit: madVR 0.92.17, passthrough HDR to display, D3D11 fullscreen windowed (8 bit). 2080 Ti set to output 60Hz YUV 444 limited 8 bit to the C9.

From where can I download madVR betas?

I haven't noticed any issues either. Running 445.78 (hotfix) with 1909 .752.

EDIT: I take that back. Just tested something in HDR, and yes, it's doing the same thing when you pull up the player UI.

Same here. Prior to this version I was using 441.66 which was also fine.

Mostly the same here but GTX 1050 (laptop) and 60Hz YUV 420 10 bit HDR.
