i have the 353.50 installer now on my disc so I could share this and by doing this it would be unofficial. i would like to stop this topic now maybe the driver will be released soon on the nvidia homepage (and i hope with openCL/CUDA) or maybe not. |

Yep 353.50 is still not up on Nvidia. MS just released their first RTM build so that may have a relation with the driver they put up in Windows Update today. I think Nvidia will release it soon. |

353.49 Hotfix is the official latest Windows 10 NVidia driver that can be downloaded from NVidia website. I do not understand all this arguing. MS never provided proper NVidia drivers that contain CUDA, OpenCL, and PhysX because MS is stupid like that. If NVidia does not have an official link to these new 353.50 drivers, then you should not be using them.
As far as 4:2:2 chroma upscaling goes - I can undeniably see the difference between selecting Jinc and selecting NNEDI3 when I zoom in slightly, so there is definitely some improvement, even with 4:2:2 output. Another thing I wanted to ask Madshi was about dithering on a 12bit display, using 10bit+ madVR setting. Does it actually make sense to use ED or whichever dithering on 12bit display? Disabling dithering on 12bit display gets rid of quite a bit of noise and yet gradations remains very smooth. I noticed another difference too. When I toggle between ED dithering and no dithering, using 12bit NVidia CP setting and 10bit+ D3D11 Exclusive mode setting, the actual image colors change as if a different colorspace is used. That makes no sense to me because AFAIK ED or whichever dithering is supposed to create a perception of more colors by reducing visible gradations (same as using higher color bit depth), but is it supposed to actually show/create DIFFERENT colors? That goes against creating a 3DLUT/calibrating TV for the purpose of seeing the image as it was mastered... Last edited by XMonarchY; 15th July 2015 at 21:04. |

I get some major back and forth jumping with v0.88.17 and v0.88.18. No problems prior to this.

Is it normal that playback (initialization) delays 3 or 4 seconds for every video (even windowed)? I tested LAV Video with CUVID, DXVA and CPU, then also with madVR, EVR and VMR-9. I say because I just did some tests using the iGPU (for some performance benchmarks) and all videos played fine within a second.
----------------------- I did some benchmarks concerning the iGPU Intel HD 4600 to extrapolate with UCFF systems like Intel NUC. Actually an Intel HD 6000 is very close to a HD 4600 according to passmark. The goal is to upscale using NNEDI. The miliseconds in brackets are the average rendering time. Using DXVA2 (copy-back) in LAV Video: (30ms) You can set all setting tuned for quality with NEDI (no neuron) doubling, this is probably better than only lanczos3 but still feels like droping frames (not reported in stats) (44ms) NNEDI3 (16) doubling only luma with everything else to minimum (optimizations) is still 3 frame drops + 3 reps off from ideal, probably needs Iris Pro to make this work, or skylake iteration of iGPU. (18-23ms) 1080p content is fine since no scaling is needed (21ms) 720p content (internally lanczos upscale) Last edited by Dogway; 16th July 2015 at 10:16. |

Not at this time. Maybe some time in the future. Quote:
Chroma upscaling is one of the less important things. So the loss might not be dramatic. But it's a loss, in any case. Quote:

This whole problem seems to be related to DXVA scaling. You could also try using a madVR scaler instead of DXVA. Quote:

So you tested this and that, but you didn't really tell us whether the delay occurs always, or only in some of these tests (and in which). Because of that I can't really say anything meaningful. |

madVR v0.88.19 released
http://madshi.net/madVR.zip Code:
* fixed: using the sharpening algos sometimes produced startup crashes * fixed: forced film mode sometimes produced crashes * fixed: weird resolution videos resulted in black screen with some old GPUs * optimized OSD rendering performance slightly * when running in a debugger, keyboard hook is not set, anymore |

I tested with this and that and I always get 3-4 second delays (with nvidia GPU), 1 second then using iGPU. Out of curiosity, can I tell what GPU to use for madVR (just like I can with LAV Video; DXVA, QS, CUVID...)?

Thank you for your answer ! I keep using DXVA/DXVA because after some testing I found it to be the most natural processing (in my case ofc). Source : Bluray 1920x1080 Monitor : 1680x1050 Zoom : 400 % Same frame each time ofc Chroma upscaling/Image downscaling |

Still the Overlay mode combined with dxva2 native with dxva chroma, luma and downscalling, gives me weird sized window, in fullscreen is ok, but the player crashes after I press the stop button - mpc-be latest beta 501...No problems in 0.88.17

And how am I supposed to debug now why madVR sometimes doesn't get keyboard events from JRMC?

Yes, it does output 10bit. And I tried experimenting with the 16bit png file, from the other thread... it seems that 10bit is working even if the TV doesn't report 36bit input. I mean, the gradient changes and there is no dithering set in madVR, output in Nvidia control panel is set to 12 bit (it's either that or 8 bit). So I guess Nvidia is not dithering, madVR is not dithering... the gradient changes when in 10bit FSE mode... I'd say it works. My beloved Kuro is getting old in the tooth... I should change it but there's no satisfying alternative so far

Thanks! Quote:
Of course I could also simply revert the change. But I think it's a "good" change. I've noticed many times that when trying to debug a media player with madVR running, the first key press freeze for several seconds, before MSVC++ continues to run. This is quite annoying. I *think* this problem should be gone with the change I did. |

Somehow it felt like I always get that, and I don't think I always used madVR. But maybe I'm wrong.. Anyway, the hotkey issue with madVR and JRMC is something I definitely want to look at soon'ish, but I can just use an older version, sure.
