Madshi ? there is no possible way that CUVID will work with NNEDI3 with newest drivers ?
Should I use Chroma Upscaling NNEDI3 32 neurons + Activate SuperRes + Upscaling refinement + SuperRes refine the image only once after upscaling is complete. Last edited by x7007; 20th February 2016 at 01:55. |

adding something like DXVA mpeg4 ASP decoding is simply not worth the time. and you gain absolutely nothing by using DXVA2 for such codecs. nvidia broke it and they don't seem to care at all. in theory DXVA2 can do everything important CUVID can do. |

Could you help me with the other question ? if we are on the subject on NNEDI3 , I just don't know if I need to enable SuperRes on both Chroma Upscaling and refinement. |

Yeah anything over nnedi3 32 neurons is wasted performance AFAIC. It's a nice sharp chroma upscaler but it most situations you won't notice a difference. Jinc AR and Reconstruction soft are my fave pics with SuperRES being a luxury if you can afford it. Luma should be where you spend the majority of your available performance for the simple fact that those changes are a lot more tangible. Last edited by ryrynz; 20th February 2016 at 04:11. |

Catmull-Rom is a special call out for Bicubic50 because it is the sharp theoretically optimal option for bicubic. Similar theoretical sweet spots for bicubic are SoftCubic100 and Mitchell-Netravali, Mitchell-Netravali is bicubic with B=1/3 and C=1/3. In madVR b = softness and c = sharpness. The proposal was any set of values where B + 2 * C = 1, with 1/3 and 1/3 as a particularly good balance between artifacts and sharpness. I believe optimal meant minimizing aliasing and ringing with varying sharpness. However, this work didn't have madVR's, or any, anti-ringing filter.

Many have updated their downscaling preferences to those, depending on the content. |

madshi, will you be extending the GPU queue to maybe 32 or 64 eventually? Same question for frames to present in advance.
I've noticed higher values produce smoother motion with smooth motion turned on. I'm guessing it has to do with how many frames are blended together. |

And personally I seriously doubt that increasing the queues increases the smoothness, as long as the value is high enough for the algorithm to work. It won't blend infinitely many frames, just the exactly right amount.

Fellows I have to express my findings.
Super-xbr 150 does wonders to Chroma, it makes the very lossy 4:2:0 appear as though it is 4:4:4. Reconstruction (sharp/placebo) does something very similar but a lot harder on the gpu than super-xbr.

Yeah, it's quite ironic that Nev and Madshi implemented support for 3D right at the end of 3D life cycle in the TV industry (unexpectedly I assume).
Nevertheless it's awesome for whom loves full resolution frame-packed 3D and madVR together.

Unfortunately their OLEDs cost an arm and a leg. Wonder if their 2016 S-UHD screens are any cheaper and still good.

Just think about it. You can watch the same movie over and over and always find something new that you didn't see before because you just didn't turn your head to look at it before. Nev and Madshi get to work |
