Thanks guys!

This is without highlight recovery, though, I guess? What happens if you enable that, too? And while we're at it, which NGU Upscaling quality (Luma only, chroma set to "normal") can the 1050 Ti do for 1080 -> 4K? Medium or High? |

a 960 is very similar to a 1050 ti and is can do 1080p23 with NGU high easily. it uses about 20ms ~ for NGU high alone.
and be aware that the 1050 3GB is on paper faster than the 1050 ti and cheaper at the same. just a matter if you can work with the 3GB it has. not a lot of versions to choice from but the price is great: https://geizhals.de/?cat=gra16_512&x...+(3GB%2F96bit) |

If translation to SDR was the cause, I expect the PQ curve tracking would drift as well but it is not. hmm...there is no bar 16, there is a clip with 64-80 bars and there is a clip with C64-C111 gradient (0.0-0.07 nits). In the former I can, with great effort and in pitch black room notice that bars 76-80 are flashing, almost un-noticebly. In the gradient clip I can see the gradient becoming VERY slightly lighter, from left to right, than the bottom black part, so I am guessing there is no crush but also that near black gradation is so barely noticable - don't know if that's a problem and it should be more noticable. |

For some reason, I can't get D3D11 native to work in 10bit exclusive mode on my 1060 It just freezes when I try going fullscreen. DXVA2 native is fine though. |

The usual uninstall/reinstall graphics drivers and reset madVR. Does it work with 8bit?
For anyone downscaling 4K HDR to SDR HD, make sure you have 'scale chroma separately' checked. Also 'Are you nuts!?' highlight recovery for HDR does wonders for clouds and other highlights and looks nicer than very high, you really want this option enabled at either of those settings I think. SSIM 2D downlscaling for 60fps 4K content is just out of reach for a 1060 6GB and my 1080 can't quite do full madVR 4K HDR -> 1080 SDR (SSIM 2D downscaling, NGU AA chroma, ED2 Dithering, highlight recovery etc), I have to enable scale chroma separately.

Does anyone use a 3GB card here? Maybe I can upgrade my laptop to another one with 1060 3GB version...

i don't have a 3 GB card so i can't say.
but i can use more than 3 GB Vram with madVR by using ngu on chroma and luma by leaving the rest in madVR normal. because 2Gb doesn't work easily on UHD with subtitles and we are using PC you just recommend 4 gb because that's more common. |

Enabling it absolutely destroys performance better used in other places, I do prefer to not have it ticked though. Prefer not to trade quality where possible.
Definitely the last thing to untick from that section. |

The GPU clock was maxed though, and the task manager performance monitor was correct by the way (checked with GPU-Z and CPU-Z). It usually is fairly reliable here. I did more tests without Teamviewer running in the background (!), using Pacific Rim for a worst case scenario (as it's a 16/9 UHD HDR movie), the readings are normal (I think). I also used a kill-o-watt to measure the actual power use for each mode (rough average). Idle use is 93W. DVXA2 NT: 18ms CPU 12% GPU 50% 230W DVXA2 CB: 21ms CPU 30% GPU 75% 320W D3D11 NT: 18ms CPU 15% GPU 55% 270W D3D11 CB: 21ms CPU 30% GPU 75% 320W I wish it was possible to use DXVA2 native as it's clearly the most power efficient mode but if I remember correctly there are banding issues with it. Both CB modes seem to use the same amount of power roughly, so unless there is a very strong reason to use DXVA2 CB, it looks like I'm going to use D3D11 native with manual picture shift, as I'll lose the black bars detection. I can't really justify 50W just for that convenience. I'll just have to select thelens memory on my iPad for each film, that's not too bad. I have everything enabled with pixel shader with peak brightness measurements, restore highlights, no compromise, NGU High chroma upscaling, plus a 3D LUT, plus some enhancements, so it's a maxed out scenario. Still Asmodian's times with a 1050ti seem significantly lower, so I might try to disable some enhancements later to see if I get similar results. Thanks again for pointing this out, it doesn't make any difference in real use but my results were wrong, as you pointed out. Quote:
I agree that an average rendering stat in the OSD would be great. Not sure why your D3D11 mode is more efficient, there is little to no difference here with CB and DXVA2 is significantly more efficient in native.

blackbar detection still runs even on a movie that doesn't need it so your comparison is not fair.
and don't you think it's odd that 70% GPU load is 21 ms and 50-55 %is 18 ms. with DXVA native even measure peak brightness is disabled which is a couple of MS if it it used. because i can't look into your system you have to make sure all use the same settings and no setting is used that the other mode can't do. |

I didn't use a 16/9 movie because I thought black bars detection wouldn't be active, I used it because it has more pixels to handle than a 2.40 title, hence worst case scenario re render times (as I said). I'm only posting results for the settings I was currently using. I'll adapt settings depending on whether I decide to use native or copyback. Measure peak brightness isn't disabled when running DXVA2 native, not sure where that comes from. You are correct though that if I was to disable the CPU features used in CB that cannot be used in native, the render times would go down in CB. I guess I'll have to test that.

you can not call one mode more efficient if you didn't test them fair.
and did madshi change this in a new test build? https://abload.de/img/itcomesfromherec1cmv.png |

I'm using ordered dithering, and although disabled black bars detection shaves 2ms and drops the CPU use from 25% to 15% (MPC-BE only), that doesn't explain the whole difference. My picture enhancements cost me around 2ms. Re the DXVA limitation, I don't know if it's effective or not, I can only report that the measured brightness is displayed with DXVA native as well as with D3D11 (I checked). Maybe Madshi can explain if the text in the settings still applies and if it does how come the OSD shows the measurements with DXVA native.
