v0.88.9/10 has fixed my issue with DX11 and my Intel GPU. Thanks!
edit: I have noticed it still goes glitchy gif like when its playing in windowed mode but I can live with that since I normally watch fullscreen. Last edited by Ava Pug; 28th May 2015 at 12:27. Reason: noticed an issue |

One final question. Apologies for my ignorance.
Do I need to make sure the average rendering time is below the vsync interval for smooth motion to function as intended and be judder free? Or do I only need to worry about being under the movie frame interval? |

If you play e.g. Blu-Rays on a 4K display, there's no further scaling needed after NNEDI3. However, in many other situations you're right, and NNEDI3 is followed up by one more linear scaling algo. In that case fixing the NNEDI3 pixel shift would be possible without losing much (if any) quality. At one point madVR did exactly that. But it caused problems (artifacts) with the anti-ringing filter, so that's why I disabled that again. Once again: Why fixing the pixel shift? There's no good reason to do that. At least none that comes to my mind. Quote:

32 bit nnedi3 on nvidia is broken anyway that's to there driver so no huge lost here. it would be nice if some can reproduce this issue like it is. you should have gotten an error report from me yesterday. this error comes when a file is played to the end with the nnedi3 error. edit: about dithering. there is a chance nvidia isn't dithering. James Freeman stated that the GPU driver "damaging algorithm" add banding so the results is not dithered. which is an indicator for this. but i haven't test this yet myself. i need my TV to do a proper test and that's not connected to my nvidia PC.

The results with Lanczos 8 and AR were the sharpest of them all and still relatively cheap performance-wise, without ever having to invoke NNEDI3. But it was never really used other than to just sharpen content by me. As such, I would not really miss it though. EDIT: madVR now has sharpening, need to retest.

Yey! The latest madVR 88.10 fixed D3D11 presentation glitches problem on my TV. With 88.8 release, I was able to enable D3D11 and Sync sub-option only on my 120Hz monitor, but not my TV @ 23Hz (I would get presentation glitches). This new build fixed it!
Someone else was asking whether they could see dithering when 10bit+ mode selected. On my 12bit TV (can select 12bit in nVidia CP) and with madVR set to use 10bit+ depth, I do NOT see any dithering what-so-ever, even though Error Diffusion Option 2 (+ both sub-options) is selected. Is that normal? Maybe at 12bit, ER or any kind of dithering is practically not noticeable? |

and getting 12 bit in a TV means nothing. it is totally default that this is possible. |

So I only get the nice smooth image with MPC/MADVR but that still leaves the question open about why it gets smooth if Nvidia Control Panel is not giving me the option for 10bcp at all. A user just PMed me telling me he sees the 10bcp option at 24Hz but not at 60Hz. I tried yesterday at 48Hz so I will check. Perhaps somehow my project is still capable of 10bcp after all. As a side not, this latest Nvidia driver seem to mess up the TV levels or at least it was making the projector detected Auto incorrectly after the upgrade. No other setting was changed. In any case, more testing to come later tonight. BTW, when in the Chroma options I am selecting the NEDDI3 32 setting but what is the SuperRes option in there supposed to do? I know it increases the performance hit but not sure what I am gaining. Thanks and sorry for the many Qs! |

madshi wants to focus on debanding effects/comparison at the moment, so he may not be to interested in answering that question for you. Chroma's SuperRes option effects the sharpness, anti-alaising, softness, and anti-ringing chroma. Most people have a hard time seeing differences. From full screen video check and uncheck it clicking apply each time to see if you can notice a difference. If you don't then you might as well leave it unchecked and save resources for other features. NNEDI3 is very resource demanding, and many people (myself included) see better performance and visual quality when they combine a lesser chroma scaler with ChromaSuperRes then they do with NNEDI3. Your opinion may be the same or differ, so experiment and make your own conclusion.
