I wonder if the debanding is done before as well. |

I feel it got much better in the latest release, but then again it can be a placebo effect. At least DXVA deinterlacing performance is now what it's supposed to be in DX11 windowed mode. I'm running the latest WHQL drivers. Great work, madshi! Maximum rendering times seem to be through the roof in some cases (24 @ 60fps with smooth motion), but I don't see that affecting playback.

Been in few big places and it was very disappointing. I use to always do dithering with avisynth- Floyd+bit of noise and this really helps with banding, specially on fades (as you mentioned). |

Hi, I want to ask something offtopic, related with video cards, anyone with a GTX 970 can answer me. I have recently changed my video card from: Sapphire HD 7870 GHz Edition OC to MSI GTX 970 Gaming. Everything works fine, games doesn't exhibit artifacts nor slowdowns. But I saw something really strange in whit colour images, i see like a vibrance in the form of bars, so I decided to see the Chroma Test and for my surprise i see anoying vibrations everywhere and 4:2:2 can be seen. I test with other test like the colour bars one and nothing seem to be wrong. Maybe it is a defective DVI output, beacuse everything is OK when I use HDMI output to my TV. I am using the provided DVI to VGA adapter. I will aprecciate a lot any answer from GTX 970 owners. Thanks in advance, and sorry for the offtopic question, it is not my intention to deviate the topic.

The first screenshot is of the original video, 1916x1076, without black bars. The other two screenshots are taken with the video shown in full screen at 1920x1200, where black bars are added. Embedded subtitles are partially shown in the bottom black bar, while external ones aren't. Both should be definitely rendered by XySubFilter since modifying the timing through its properties window affects both subs. Last edited by mcn; 4th November 2015 at 07:57. Reason: Removed the part about reloading the subtitles since it was wrong |

MadVR Option High End PC DXVA2 Alternative Configuration
chroma upscaling NNEDI3 128 Neurons Image Doubling Always use NNEDI3 to Double Luma and Chroma Resolution using 128 neurons Image Upscaling DXVA2 Image Downscaling DXVA2 smooth motion Enable Smooth Motion only if judder without dithering Error Diffusion Option 1 Video Codec CUVID with hardware deinterlacing I found this suggestion on a forum. In this senario, by using dxva for upscaling and downscaling does image doubling work for example for 720p content? ı am not sure it will work while using dxva.

Sorry to say, but these settings are simply bizarre (wth invent people stuff like that?).
NNEDI3 128 neurons for chroma are a huge waste of performance, even 32 are quite luxury (with filmed content, NNEDI3 will hardly ever look noticeably better than Jinc AR for chroma). Always using NNEDI3 for image doubling is also pure nonsense in 99% of cases. Linear scaling algorithms like Jinc introduce more artifacts the higher the scaling factor is. With <1.5x scaling, there usually hardly is an advantage of NNEDI3 over Jinc AR. And 128 neurons are an insane count and most content doesn't profit much by the additional neurons, compared to 64. DXVA scaling is simply bad quality wise. Don't do it if you aren't forced by badly slow hardware. Use Jinc AR and Catmull-Rom AR for downscaling instead. Don't use Error Diffusion if you can't see a difference for yourself. Instead, stick to normal ordered dithering of madVR. Don't use CUVID, as it's a blackbox to developers (Nvidia doesn't grant nevcairiel or any other dev any control over it). Instead, use DXVA2 Copyback. It achieves the same quality and speed, but it doesn't have any drawbacks (instead of worse compatibility compared to software decoding, which almost never is an issue). |

If you aren't using SuperRes, image doubling won't make much a difference at a 1.5x scaling factor.

looks like they are both the same chip with a different name. both have about double the speed of the r7 250 |

My MSI R7 265 is not bad either especially for it's price point. It's like having a R9 270. I know it is by no means top of the line but it does a decent job with madVR and NNEDI3 Image doubling.

SupeRes is pointless as well, as it likely just sharpens the image and I literally can't tell what it does after a good hour of viewing with/without it. Last edited by AngelGraves13; 4th November 2015 at 17:01. |
