madVR - high quality video renderer (GPU assisted)

[Ampallang]

As far as I heard they are both equal. only nvidia can't do 10bit output and the vega needs more power.

@madshi

I know you are busy with the HDR tone mapping algo work, but would you please consider moving GPU hard coded bars detection a little up in your to do list. Copy-back is really inefficient with UHD let alone when we add the tone mapping algos.

Thanks & Kind Regards

Great picture looks nice with the 3d luts.but the picture had more punch in highlights with the tonemapping shader math so far. But the colors Looks amazing. Have to test further.

@ampallang: did you try tweaking EOTF Nits settings in Lightspace's Convert color space dialog? I'm testing Lightspace with DPS licence but don't seem to be able to export the LUT for MadVR so can't give you any more ideas.

dxva copyback but still stuttering, have any others with the new 2080 card experienced the same? with my old gtx 1080 i didn't have any stuttering at all no matter if i used d3d11 or dxva and my sttings in madVR are the same, surely the new 2080 schould be able to use the same settings in madVR

Just got my asus strix 2080 ti and I am experiencing the same stuttering issues. Games are working fine. Looking at gpu clocks the gpu is not stressed at all while playing madvr. Power is set to adaptive. I have even tried default madvr settings with no image upscaling but still the same issue. Latest drivers. Any suggestions please?

Everything was fine with the 1080 that I swapped out.

Edit: No issues with evr.

Not jet but will do this soon. Just verify compare the results BTW. The 3 methods 3d lut, pixelshader with and without hdr flag and normal hdr via tone mapping done by tv. Alot of tweaking can still be done I think but nice to know what will be possible and which content works on Lg oled and what didn't looks so great in my eyes.

Hi,
after some tests with AMD RX560 now I'm testing with Nvidia 2070.

I follow a guide from hifi-forum.de. http://www.partyfotos.de/madvr/settings/

In this guide is a screenshot from madVR 0.92.11. I' have installed madVR 0.92.17.
In the HDR-settings of madVR 0.92.17 for my device I have no "Convert HDR to SDR by using pixel shader math" and "Convert HDR to SDR by using pixel 3DLUT" .

is this correct? Are these options dropped from the newest version?

[Warner306]

Yes, it is all different, but simplified greatly.

After spending about 8 hours trying to debug this I have finally figured out the problem. While playing a video on my TV (connected via HDMI), I get a lot of CPU usage with no load on the GPU. LAV video shows <none> in the active hardware decoder. If I play the video on my PC monitor I get RTX 2080 ti as the video decoder and very little load on the CPU. I have tried DDU + reinstall drivers with no success. Any suggestions would be greatly appreciated as I am practically at my wits end trying to figure this out. Thanks in advance.

Is your TV connected to the iGPU and the monitor to the discrete NVIDIA?

[austinminton]

Both connected to the NVIDIA.

[el Filou]

Did you try switching between the various DXVA/D3D11 options and see if some of them give a different result?
Is the monitor set as the first screen in the dual display setup?

[ryrynz]

Why not just disable the iGPU in the BIOS?

[austinminton]

I went for the nuclear option of installing a fresh copy of windows on a new partition. Now I have hardware acceleration on both my PC monitor and TV. The GPU gets load when madvr is running on the TV as well. But the stuttering issue still persists. I have tried making the TV my main monitor. I have also removed my PC screen with my TV as the only monitor. Rendering times are well within limits at about 20ms with NGU high for scaling and chroma. On windows 1803 with latest nvidia drivers 416.81 and Lav on 0.73.1. madvr on 0.92.17. This stuttering is very similar to what another user mentioned earlier which I quoted above.

Edit: If I use FSE my stuttering issue is solved too. Thanks everyone who took the time to reply to my issues.

[Warner306]

Does the problem go away when using lower values of NGU or something like Jinc or super-xbr?

[Grahlwur]

Is it possible to select which angle/eye is viewed when watching a 3D-bluray in 2D? It seems to default to the "first" eye, but I can't find a way to change to the "second" eye.
I tried playing around a bit in madVR settings under devices -> <device> -> properties and rendering -> stereo 3d, but I can't seem to find a way to accomplish this.
No matter which settings I use in madVR, LAV Video Decoder says "Active Decover: msdk mvc", which makes me think it's possible to write a function to for example enable the "swap left / right eye"-checkbox for "3D format: none" to accomplish this?

When watching 3D encoded as SBS, I can select eye pretty easily by using Pan & Scan in MPC-HC to zoom in/crop to see only the eye I want. However, this does not work with a proper 3D-bluray since the Pan & Scan is happening before madVR does its magic. Meaning I just end up with SBS with zoomed in picture on both sides.

I realise this is a kinda odd question. What I'm trying to accomplish in the end is to analyse fullscreen screenshots of both left and right eye from 3D bluray both with themselves and the same frame from 2D bluray.

1) Is it already possible to select eye in madVR and I just haven't figured out how to do it?
If no:
2) Is it a feature that can be added without too much hassle?
3) Anyone happen to know if this is possible somehow in MPC-HC itself with LAV and madVR?

Also, thanks for an awesome renderer!

Regards

Yes, I am using 2080 and get stuttering also even through CPU/GPU utilization is low and rendering time is low. I was getting no stuttering with 1060. Only thing that prevents stuttering for me is enabling full screen exclusive mode.

No, I get this problem on my 2080 ti even if I match the resolution (for no upscaling). The rendering times are very very low but the problem persists.

The only way to avoid stuttering is to enable FSE.

This was not a problem on my 1080 which was the exact same vendor and model (asus strix).

It could be that drivers for the RTX cards are still buggy.

Try using something other than NGU for chroma and image upscaling.
