If i have a rec709 lut in the rec709 slot along with pass HDR through to display checked (full HDR compatible video chain) will madVR ignore the lut when playing 4k HDR? I only want the lut active when I am actually watching rec709 content and not when watching 4K HDR.

The OSD will indicate if and which 3DLUT is being used, easy enough for you to confirm.

Hey guys. I've noticed a problem with my madvr setup and I was hoping someone had some insight for me.
I have a 144hz monitor and while using madvr and xysubfilter I was getting dropped frames the first time subtitles were displayed. It always happened at the exact moment the first subtitle was shown and never happened afterwards, nor did it happen if I rewound to the beginning and watched the same scene again. I changed my refresh rate to 60hz and the problem went away, so I assume this has something to do with that. I also tested at 120hz and I did not notice a problem. Now I'm not sure if this is actually a madvr problem or an xysubfilter problem seeing as it only occurs with subtitles and also doesn't happen if I switch to the internal subtitle renderer in mpc-hc. I also don't get this problem if I playback with mpv, but obviously that doesn't support madvr. Thanks for the help. |

showing subtitle the first times add the hole process and it looks like all buffered frames have to be re rendered. dropping frames in this case it pretty "normal".
thsi should only affact aasfilter mod and xy subfilter. i can't remember it but i'm pretty sure i brought this up a couple of years ago. |

There is an OSD bug that shows the SDR 3DLUT being used even with using HDR passthrough, but the 3DLUT is not actually being used (a test 3DLUT that should change the image a lot does not show any effect). The SDR 3DLUTs are only active for HDR content when madVR first converts HDR to SDR by either method.

I came across something strange while letting madVR upscale a cute little 240p movie to 4k resolution. Please have a look at the following output:

EDIT: I have also a second question. Isn't it possible to apply pixel shaders while using D3D11 copy-back decoding? mpc-hc says it can't use pre or post resize pixel shaders and I simply don't know why. Last edited by waldnebel; 7th July 2018 at 19:56. |

Im not sure about ngu upscaling abilities after quadrupling step. Anyway quality is bad, because source resolution low and scaling factor big. |

I've tested NGU on "Ultra Low Definition" material, e.g. 360p YouTube, and it's just too weird, the picture looks like a watercolour painting.

Thanks - I could do that, but so far I've only the one and it is not that great of a movie. I presume however the "better" option will be to use the HRD->SDR conversion option that is currently being work on (when it is ready) for all HDR content?

only +54% in some benchmarks and apparently Polaris doesn't like NGU huh, I got all bells and whistles enabled(SSIM 2D, ED2, NGU, Luma & Chroma SuperRes) with my 7850 @1080p so I guess I'll have to throttle it all down a good bit for 2160p and even a RX580 wouldn't quite be the savior either as it would appear. Apparently Club 3D make dongles that convert DP to HDMI 2.0 allowing 2160p60 on any semi-recent AMD so that's another option, hopefully hiccup-free Last edited by leeperry; 8th July 2018 at 06:10. |

Which NGU? I prefer NGU Anti Aliasing for <SD.
