36-39ms per frame should be fine for 24p content. What are you using for dithering?
You could try cropping as well, that might help. @huhn: UHD is supposed to be slower because tonemapping is done on more pixels than lower res. Last edited by quietvoid; 18th January 2021 at 17:16. |

PCI lanes -> Check the connection of your GPU with your Mainboard. A mechanical PCIe x16 slot may only have 8 or maybe even only 4 lanes electrically. It is rare, but sometimes users do strange things when building computers.
What mainboard and GPU do you have? |

On page 14 you can see the PCI and PCIe slots 1.) Which one do you use for your GPU? 2.) Do you have any other PCIe cards installed which can cause the x16 lanes to be split up to x8 and x8 to the GPU and the other PCIe-card? Can be a PCIe-SSD, ... 3.) What GPU do you use? |

I would not worry about the PCIe link; if it works with those trade quality for performance options enabled the problem is not the PCIe link.

there are big where PCIe issues cost unregulary performance you can see that when the first step and the last step have unusual high rendertimes.
which is kinda present here. Quote:

That motherboard and slot should be fine for 16x PCIe 3.0.

i'm not even question that it is much more likely that the GPU is just not fast enough.
the reason i would look into it is that blur dif is the first step and blur dif usually takes 0.3 -1.50 ms on this screen it's 4.85 ms. on the other hand i don't even know how he got it to be the first step. edit: and the 580 is a pretty fast card when NGU isn't used which is the case here. |

Does the GPU simply being too slow seem unlikely?

I have a doubt.
Since black band detection is done by the CPU and not the GPU, could it be that my current Core i5 3300 is insufficient? So is it better to change the processor instead of the video card? Could an i5 10400F fit? I also tried to see the percentages of CPU utilization with DXVA2 copy back active, and I saw that with an HD movie the usage was 20% while with a BD UHD it went up to 70/80%. Thanks for your help |

Have you tried with it disabled?

Certainly, these are the CPU usage data:
d3d11 native & black bar detection: CPU 20% rendering 38 Copy Back automatic & black bar detection: CPU 70% rendering 68 Copy Back automatic NO black bar detecion: CPU 38% rendering 68 |

4K/UHD Monitor (27")
Asmodian,
I have been using your config suggestions for some time and to very good effect; many thanks. Meanwhile I have an issue where I wonder if it is related to madVR or to the videos shown. Whenever I run a lower-resoultion video on this screen at its native resolution (3840x2160) it comes to judder, with or without smooth motion enabled. However, the judder goes away when I reduce the resolution to 1920x1080. Is there anything to be done ad madshi level ? Thanks in advance |

It is very likely that your GPU is not fast enough to run my settings at full resolution.
What GPU are you using? What do you mean by lower resolution, anything less than 1080p?

Thanks for the prompt response.
By lower resolution I mean 720p or less; but even a 720p is not always giving trouble. Just for clarification: I am not using either of the two settings.bin that you keep available for download (I tested with them, but couldn't get them to work) but rather the basic settings that you mention in the text on https://forum.doom9.org/showthread.php?t=171787 My graphics cards is not great; it's a Zotac GT 1030 2GB. But no problem with films of 1080p and up and sometimes even 720p. |
