you can use 64 bit openCL in 32 bit mpc-hc try the workaround.
delete the reg key start a 64 bit player and use nnedi3 and than try the 32 bit player again. madVR is only creating one openCL kernel if the first openCL kernal is 64 bit this may work. i can't remember a change to this behavior so it should work. give it a try... |

nice idea but that didn't help either. I just think that it doesn't work with nvidia in 32bit applications. I'm gonna ask a friend to try out, I know he has a GTX 980 TI (Maxwell). and I'm eager to hear what 32bit player ryrynz was using.

You are not alone. I've had the same problem since the day one when I started usind madVR+LAV with 3d movies. Movie is fine but subtitles are in wrong depth. I've also tried different subtitle engines, original BluRay discs etc. but with no luck. |

RX 470 user here. Win7 64bit, 16.11.4 driver. Ive tested a few different scenarios and basically when using the new algo as image doubler for luma NGU-med = NNEDI3 64 and NGU-high = NNEDI3 128 performance wise for me. Changing upscaling from Jinc to CR gave me -1ms of rendering time. Anime with NGU looks really good to me. Thanks!
Just tried a movie as video source and it looks hecking "natural". Well done, madshi! Last edited by pose; 23rd November 2016 at 19:18. |

okay my friend with the GTX 980 (v375.95) just reported back and to my suprise the NNEDI3 problem doesn't occur on his system. he tried it with the 32bit version of MPC-HC. so it seems as if this bug indeed only happens with Kepler and Pascal GPUs but not on Maxwell ones. how weird.

After more testing with several SD movies, I've gone back to NNEDI3 128 from NGU-high. A large part of my collection is B&W SD, with widely varying source quality.
madshi is right that NGU works best with high-quality sources. My Blu-rays look great with NGU-medium (the most my GTX 1060 can manage for high bitrate sources). Thank goodness for profiles! |

madshi, I'd probably rename NGU-low/medium/high to 1X/2X/3X so that people know that they're passes and not really lower quality.
I'm able to do NGU-low for chroma and doubling luma + chroma w/ Jinc downscaling on my 1080 GTX to 1440p. NGU-med causes my MAX (5s) stats to hit 47ms once in awhile, so it's unacceptable to use it. Last edited by AngelGraves13; 23rd November 2016 at 21:57. |

Fair enough, your assumption was wrong also. And yes StinDaWg I know when to use that word, talk about a petty post. |

I had various theories about the problem that haven't worked out so far. I'm still interested to hear what 32bit player you were using though. |

Given that this issue occurs with quite different systems in the same area (32 bit OpenCL) it might possibly not be a driver bug. This will not be easy to troubleshoot, I can't recall ever having visual corruption with NNEDI3. Did you try what huhn suggested? Also did you try running the reset defaults batch file in the madVR directory? I've found this to fix the odd issue like this over the years. Also, just for the hell of it test madVR 0.87.21 & 0.87.0 which are the first revisions where NNEDI3 made an appearance in case any madVR code changes have affect on the output.

I've this issue, only running Madvr.
Only when reproducing (not in pause) and mostly noticeable on dark background, i've this sort of "flickering" like barely visible translucent horizontal bars. Like a sort of "signal interference". This can't be captured on screenshot. What could be?

Well NGU seems to be pretty damn awesome. I can use NGU-low for chroma AND both luma and chroma doubling with my AMD HD7850 GPU and the fan isn't even 100%. I know that at least luma doubling is working, because of the obvious quality change, but from what I quickly gathered from this thread, this might not be how it is supposed to be? Should my setup be struggling? OSD seems to be working. Anyways, I'm not using either chroma or chroma doubling NGU other than for testing purposes. However, bilateral-NGU could be interesting, if it's within reasonable performance requirements.
On a personal note, I'm very happy to see NGU to land, since this is probably the first time that even my friends, who don't normally care for picture quality, actually noticed that things on the screen changed when I switched from super-xbr 100 to NGU-low. Can't give higher praise to madshi than that. @leeperry Looks like you still have your 7850 and 13-series drivers? Could you report some numbers for comparison? I'm on the latest 64bit crimson. Same card. @ryrynz You saw it necessary to tell me that big screens don't matter, only the distance from the screen. You do have some attitude and nobody is being too much of a dick about it. Let's all be friends, shall we? |

My 65" TV is about 2 1/2 meters away, my 24" screen encompasses more of my vision than the 65" TV does and I can resolve more detail too. This isn't attitude it's simple science mate. |
