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

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?

Why not just disable the iGPU in the BIOS?

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.

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

Swap eye when watching 3D in 2D?

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

Everything was fine with the 1080 that I swapped out.

Edit: No issues with evr.
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.

Stuttering with cubic chroma and xbr scaling as well.

Don't forget to set NVIDIA "power management mode" option to "Adaptive".

Or even better, "Prefer maximum performance".

Adaptive is perfectly adequate, unless you want to heat your room.

Not in every case tho, adaptive makes rendering spikes in the avg stats and max stats.

Who cares about the stats really? They're a means to an end. As long as it falls under frame time for every frame and the noise/heat is acceptable to you then you're fine, how hard the card is operating at isn't that obvious from the stats alone.
Adaptive is perfectly adequate as Nev said, Prefer maximum performance is clock speed and power consumption overkill as Adaptive does a really good job of sorting the right clock speeds for the job.
If you're pushing ~90% of your frame time you may run into frame drops though.

I encountered a weird problem: when using MadVR (with any player) + dual screen, everytime I minimize/restore the player on main screen, the playback will stutter for a bit. It doesn't happen on 2nd mon, or if I only connect one monitor.

does anyone have clue how to fix it? The OS is Win764.

Thanks in advance.

I think it's something madshi was going to look at sometime in the future, not much you could do other than try changing the power mode for your graphics adapter and perhaps increase/decrease the GPU buffer.
Try playing with a few options and see what helps if anything, do defaults still do this?

Yes power management mode is set to adaptive. I have tried all the usual solutions and nothing fixes the stuttering besides FSE. A couple of other users have mentioned the same issue on their new 2080 ti cards as well. Is there anyone who can get stutter free playback on their 2080 ti without FSE? If so please share your settings and I will try them at my end too.
