Now it's back, and I never had a delay on it before. Ah well, have to live with it now I guess. |

I had a 980Ti until a few months ago, I don't think I ever saw 0 dropped frames on open or seek.
I didn't try to optimize settings to achieve that though... I usually run pretty aggressive settings. Though it does seem to drop more during open/seeks now than it used to.

Btw, I'm a little confused hear with chorma uspacling. There is two separate options for chroma upscaling - chroma upscaling tab and chroma-upscaling option in image upscaling tab. And If I chose to sue ngu med for chroma in both tabs I get: chroma > NGU-med luma > ... chroma > NGU-med seems wrong. Is it supposed to happen? |

Lanczos3 AR should be the "normal/low" option and Bicubic60 AR the "low/very low" one, or remove it completely. Seriously, I hope that madshi will gives us a little more choices for chroma doubling. There is too much hate on chroma... and I need to test more combinations The new users can always use the "let madVR decide" option anyway. |

The average user may never get that far and give up for NGU medium or low without knowing they left performance on the table.

FYI: Nvidia's recent drivers have made even "adaptive" power settings glitchy with madvr+mpc-hc with low power modes when playing certain files on my system. I can recreate the low power bug with a H.265 8-bit file. Currently, I've set MPC-HC64 to use "prefer maximum performance" because of this problem. It does not matter if you choose higher load on madvr, the driver will not turn up the power mode from optimal or adaptive. Some older drivers might have worked on "adaptive" settings, but the most recent one (376.19) on my gtx980 will only do the 650mhz gpu/800mhz mem if you do not manually change the setting.

The chroma upscaling option in image upscaling is for scaling the chroma to the destination resolution, if that is above the luma resolution. This option is much less important, you have already doubled the chroma resolution so there isn't much fine detail to preserve. This is why you get the two chroma entries in the OSD, the first one is reasonably important but the second one isn't. I wouldn't use NGU-med for chroma doubling unless I was already using NGU-veryHigh for luma doubling. All the chroma scaling comparisons posted recently are for the first chroma upscaling option, it is hard to find samples which show obvious differences with the chroma options in image upscaling.

try to disable HEVC hardware decoding in lavfilter a cpu is usually not really slower but doesn't stress the GPU. |

MPC-BE; LAV-Filters; xySubFilter; madVR;
give Problems with Subtitles (idx/sub) and cropped h264 Video packed in a MKV: I have chosen in madVR (under "zoom control") to move the subtitles to the bottom of the screen/window; but in the case of the cropped Video the Subs remain always within the activ/Video area (I'm in full Screen, not windowed); also in xysubfilter the "override Placement" Option does not allow to leave the active Video area; is that a bug, or am I missing something? Thanks |

Render times aren't the issue here. The GPU refuses to go higher than low power mode when I play the file. When I choose "prefer maximum performance" there is no issue. If I had not monitored my gpu core speed and memory, I would have thought something was wrong.

Now, I can not activate the bug even with "optimal" AND H/W decode enabled. I haven't checked if s/w decode would have worked or not but right now, everything is working... I will investigate further. I'm very confused now. EDIT: one thing that has changed is, I updated LAV to the latest nightly. |

you get an artificially created sharpness boost with Luma Doubling why do you want to use it? its easier to bump up the sharpness on your display instead and you get the same effect with moire patterns all over the place. run the shaprness and oversacan file from the avshd709 disc and you will see how shitty luma doubling looks. but you decide if you want to wreck the image or not or you have the sharpness and overscan test here http://privat.bahnhof.se/wb192876/5-...20Overscan.mp4 for best result use Chroma Upscaling Only or visit specsavers optics for new glasses if its not sharp enough Last edited by Patrik G; 12th December 2016 at 00:33. |

To each their own. I like the sharpness and know that ordinary image upscaling cannot reproduce sharp enough images, let alone edges that are too sharp. I'd rather border on too sharp than not sharp enough. Edit: I didn't know we were talking about 200% supersampling. Of course, that is less than ideal.

Luma doubling is not the issue in this example, messing with an image that is already at the display resolution is the problem. If you want a single pixel black and white checkerboard to look the same then don't use 200% super sampling.
