Low in current version can playback 720p -> 1080p with a little bit higher rendering time than 576p -> 1080p with Old Low. Considering AR of consequent downscaling cannot be disabled anymore, it would have been more faster. |

I don't play all latest games, some games support sli, some not, latest watch dogs 2 support it. And madvr not sli-friendly now, i get better performance when sli disabled, do not see anything ridiculous here, some would like see changes here if it is technically possible. |

Haven't had to use NGU low, other than for chroma upscaling. Hard to tell if it's working well or not.

NGU low comes off a bit messy for chroma. The 'very high' is quite nice though, but the same issues are there with it as for luma, it brings unwanted details out into the open. Once it gets it's luma guidance it might just become the best overall chroma upscaler but the performance impact is significant in comparison to other options. |

Bicubic 150 and SSIM 1D are both sharper than Jinc and Lanczos 3. For them all I think I prefer Bicubic 150 even more than SSIM 1D looking at the zoomed pics. But please think that you were not be able to notice such differences between them at normal viewing conditions. Plus Jinc costs a lot ms for downscaling compared to SSIM 1D and even more with Bicubic 150.

I think the goal for madshi is to make NGU just an option like Jinc without any drop down menus for upscaling. It'll likely all be automatic at some point and the OSD will likely remove any info on the downscaling steps involved. The quality needs to improve a bit more before that can happen. It's just too sharp at the moment and needs a variable level of soften edges depending on the level of NGU.
I actually wouldn't mind it being that way and behaving more as a scaler than a doubler, but we'll just have to wait and see. |

NGU low is a definite improvement over the other "dumb" scalers (jinc, bicubic, lanczos). I think it's the go-to scaler for low-demand laptop playback.
Otherwise, if you can run it, I find NGU high (the new high, old medium) is a breakpoint where the image becomes noticeably better. |

I see there's been a lot of discussion since I last posted about my issue but I have done some more testing, this time manually putting my PC into sleep. The results are different than when my monitor first goes to sleep and the PC sleeps afterwards.
With MadVR and zoom player or mpc-hc the results are the same. If the PC does go to standby and return the video is always green and I have to restart the player for it to work again. With mpc-hc using the EVR it doesn't happen. It also doesn't happen 100% all the time I manually sleep but does when I leave my computer to sleep (monitor turned off first). The bsod I get that reboots the PC before the PC is allowed to go into sleep points to ntoskrnl.exe 14a510 but when the PC bsods on return from sleep the bsod points to dxgmms2 blaming the nvidia driver. For a while I didn't notice this was related to madVR so I've carried out various steps to solve it already. I've made sure there's no memory fault with my PC by running memtest86 for 48h, I've checked with prime 95 for 24h and I've monitored temperatures to make sure they aren't too high. First thing I did was do a complete clean install of the nvidia drivers. I'm not sure why I have this silly problem but it would be great to get to the bottom of it. Anyone have an idea what it could be? Is my graphics card faulty? Sent from my Nexus 5 using Tapatalk |

Catmull-rom is the same as Bicubic 50 which is soft. There is nothing wrong with using Bicubic 60 for chroma upscaling. I use it by choice with jinc for luma because it looks better than jinc/jinc to me, and also because when it comes to colour, catmull-rom and bicubic are the chromas that match the colours of nearest-neighbour. I don't know about the newest algos as I never tested and they require more gpu anyway. The goal is not to make stuff sharp as a tack. When image editing, good quality unsharp masking after downscaling stops at the point where the sharpen just barely becomes visible via preview on and off, this is usually on an case by case basis for dialing in the numbers so I do agree with the selection of 60 here, because 75 was already on the sharper side.

Just do not leave player running when you need to step away from PC. Also it's generally bad to let PC go to sleep, it somewhat works for laptops because battery life, but there is no need to do that with PC. So many things can go wrong with modern GPU drivers, probably that's what happening, you are not saving word document into RAM, it's a bit more complicated with rendering I think. Set it do disable display and never go to sleep, most safe option. |

I am now able to run NGU-Low on 720p60 videos, where I couldn't use any NGU levels before with my HD 7770. It's also significantly faster than Jinc+SR2. There is a bigger difference with SD videos. There is a noticeable quality increase between NGU-Low and NGU-Med, with then smaller increases all the way up to Very High. Surprisingly I am able to use NGU-High on 480p60 videos with render times around 10ms, so it's not much of an issue. If you are somehow able to make NGU-Low sharper without increasing gpu usage, that would be good though. Please no. Bicubic 150 AR is a very fast and good alternative to SSIM. It's even better in some ways judging from the pics posted above (we are talking microscopic zooming levels anyways, in practical terms they are almost the same). After upscaling good content with NGU, I don't want to then make it blurrier with Catmull-Rom. Last edited by StinDaWg; 1st December 2016 at 09:06. |

I think I might start another thread specifically targetting any issues with madVR and the hardware involved. I will emphatically state the purpose of the thread so people don't try an argue that it works fine for them so there isn't a problem. From what I have found, the issues seem to be more prevalent on Geforce GTX 10xx models and Radeon RX models (the 400 series). The old R9-280X worked beautifully and on affriend's R9-280X (different other hardware though) runs beautifully with similar settings, so it will be interesting with the responses. |

I wanted to give some feedback on the new settings layout. Personally I do not like it much as I feel its a little confusing. At the same time though I can see the original way was probably not the best either simply because it has elvolved over time. Both ways kind of over complicate the settings. I have a suggestion of a settings layout that may work but at the same time I guess some may not like it and it would be alot of work for madshi given it probably needs the current system demolished and rebuilt...
My idea is under 'scaling algorithms' there should be three sub option windows. - Movie Original - Movie Upscaling - Movie Downscaling Under each of these settings are dropdown boxes (much like the new doubling options) and other settings that follow the rendering process, from top of page to bottom of page. The user can then choose how chroma / doubling and everything else is handled as it passes through the rendering process. Movie original would be for example where a 1080p move is output to a 1080p disaply. The other two are self explaining. Would something like that be workable madshi? What do you power users think? I feel it would simplify the options greatly but thats just my opinion. Last edited by Razoola; 1st December 2016 at 10:22. |
