I was adjusting levels of some badly encoded videos. I found that there is no change in black level when I go from black level -8 to -9 using shortcut key. From -9 onwards again the levels change properly. Similarly there is no change in white level when going from -6 to -7. This is seemingly a bug. Shall I post it in the bug tracker? Or I am missing something here?

I am able to run sharpen edges on a GTS 450. Try switching to Ordered dithering.

edit even with latest driver, its the same, cannot use the new algos, gpu usage jumps from 45% up to 100% as soon as i activate any of them. Adaptive Sharpen does not have that problem. Last edited by truexfan81; 21st November 2015 at 23:37. |

Can you try this and confirm if it works for you:
1. Play a 0% white video clip (you may even use the black borders of a blu ray movie for this test) 2. Force “Source levels: PC” using shortcut keys 3. Now set Black level -16 using shortcut key If you get the final Black level as 0 then sure it works for you. I get the final level as 1 (and this is due to no change in Black level when going from -8 to -9). Last edited by omarank; 22nd November 2015 at 05:57. |

Hello!
I have been a long time reader, and I own an Acer Laptop, with a i7-4th generation and a gtx860m video card. Nvidia drivers are a mess, I jst reinstalled windows and I get crashes with every time I open madVR (using MPC HC + internal LAV + madvr). After the first crash, everything works fine, but I cannot save profiles from NVinspector, to make MPC-HC use madvr, meaning I have to set the behaviour every time I restart. Also, about edge thinning, the algorythm is superb, I can watch even SD videos in FHD and they don't have aliasing anymore, and look sharp, but edge thinning enabled in both post processing and upscaling refinement and set to 4 in both creates some artifacts. More exactly, it will make some places thicker, and create some waving. It is especially visible with Anime materials, it is not visible (until now) with movies. Anyone knows how I can solve this problem? |

I watch some videos got from amvnews.ru, and some of them are probably badly encoded, and this is what causes the frame drops, so no big sweat, but Optimus really breaks my fun , erasing my settings, and making me have to re-set settings through Nvidia Inspector every single time I restart.. Also , I became curious on what the differences between NEEDI3 and jinc chroma upsampling are? I mean, I am unable to see any, but anyone has any examples?

Georgel,
If you get crashes, you might want to disable any overclocking for starters. Also, there is no need to max out madvr settings, bigger is not necessarily better. Especially on sharpening algos. For example, I'd consider any picture destroyed at strength 4. There are chroma upscaling comparisons somewhere in this thread, but I can't find them right now so you just have to take my word - chroma upscaling is less important than luma and if you can run jinc for chroma you are totally fine and maybe even that is an overkill. I use bilateral. Did quick google search and found this page, maybe it will give you some sense how big or small of an effect chroma upscaling has http://wiki.mikejung.biz/MadVR_Chrom..._Image_Quality Last edited by YxP; 22nd November 2015 at 14:57. |

However, the difference can be quite noticeable with artifical content like found in news broadcasts (sometimes they can appear in some way in movies), emblems, cartoons or video game captures. |

I have no overclocking on, and I use NVinspector, not to overclock but to enable MPC-HC in optimus to use my Nvidia GPU (without manually using NVinspector, MPC-HC is forced to run on intel gpu, and this includes madvr). I had a discussion with Nvidia, and it seems they make the hardest efforts possible to disable people from using Nvidia Gpu for video playback, because it consumes more power this way. My scaling algorithms page looks like this: Chroma Upscaling Image downscaling image doubling image upscaling upscaling refinement. I do not know where luma upscaling is? I mainly watch anime, and it shows visible differences between bucubic and jinc, but no differences between needi3 and jinc (maybe I do not pay attention to what I should?) I solved the crashing problem by reinstalling video drivers (Nvidia is really bad at making drivers, even more when you consider that they know that the gtx 800 series has problems, but nobody from them does not care to fix this ![]() I am already posing myself with the general question of if I should get a laptop that has a gtx980 inside or wait for pascal release, as my gtx860m does not cut it for all my games nor I cannot set all options on highest setting in madVR (I am spending about 40% of my time watching anime). Any opinion and advice is very welcome! |
