Lower queues are needed on slow hardware to get a picture. I use 6/4, half of the defaults, for faster seeks and don't see any problems. I had asked madshi awhile ago if he'd consider allowing smaller queues to allow madvr to work with slower hardware, he said it wouldn't work.

I guess this could fall into the auto configuration feature in the future. Determining the best queues for your hardware. I don't think this particular problem is shown as dropped frames. So knowing what's going on here might be of some value. |

Not sure auto queue settings could ever work consistently and it's been tried. A few months ago someone would get dropped frames in some scenes with the highest queue setting on old/slow hardware hence the larger buffers were added. On my older hardware I couldn't get a picture at default queues and needed to lower them and SD played fine, no longer have that laptop. Another example is madshi has/had an nvidia 8500/8600(?) that needed to increase queues to prevent dropped frames, the 9500GT I have starts dropping frames if I go above 16 or so with fhd, going with low queues doesn't cause dropped frames.
It hasn't been investigated much but there's nothing obvious responsible for these varying results.

Hello gentlemen
I'm fairly new to using MadVR, and I am just wondering what the best settings are to achieve the sharpest picture while keeping aliasing to a minimum? I use MPC-HC coupled with ffdshow. If I enable "sharpen" on ffdshow I get quite a bit of aliasing but it does enhance the sharpness. What settings can I use in madvr to get exceptional sharpness without going overboard with the aliasing? I have an Nvidia GTX 680 GPU. |

If you want to use post-processing to enhance the image, follow PetitDragon's advice and use shaders in MPC-HC. As a side note, LAV Filters (also included in MPC-HC nightly builds) are the codecs of choice recently and work with madVR nicely. |

michkrol....I *DO* in fact want to use post-processing to enhance the image in MPC-HC but you mention I should use shaders....how do I use shaders in MPC? I don't see anything that says "apply shaders" in the MPC-HC options? Or do you mean use "external filters" such as ffdhow, etc? Oh by the way I should mention I watch a LOT of Anime! In fact 95% of the content I will be watching on MPC will be anime. Last edited by isamu; 14th September 2013 at 22:19. |

There's a newer version of Lumasharpen at http://dropcanvas.com/l46x9 There's a guide available there too. The easiest way to 'install' it is save the txt, change the extension to psh and move it to the mpc\shaders directory. Feel free to tweak it to your liking, the only ones I changed were strength=0.9 and pattern=8. I prefer is as a pre-resize shader but try post-resize as well, you could even use it as both for a lot of sharpening.
Finesharp http://avisynth.org/mediawiki/FineSharp you'd load in the avisynth tab of ffdshow. LSFMod http://avisynth.org/mediawiki/LSFmod is another avisynth filter. Unsharp <30 strength in ffdshow's sharpen tab is worth looking at as well. I've used them all regularly but find LumaSharpen has the highest sharpen to artifact ratio to my eyes. You'll have to decide which one you prefer.

There are other known issues with Intel's newer drivers with this option enabled. Could you confirm that's the case with your setup? |

im occasionally hearing of problems of stuttering from people when madvr switches their display to 23.976hz.
Does anyone know what is causing this or what to suggest to those with this problem? Oh, i guess one thing they can do is make the default refresh rate 23.976 hz. Last edited by mindbomb; 16th September 2013 at 06:52. |

Hi,
I tried doing a bunch of research, but how in the world do I use pixel shaders with MadVR in KMPlayer? It seems like there is almost no information about this... I tried looking through the JanWillem32 thread but didn't get too much out of it. Would I see a noticeable difference if I add pixel shaders into the mix? I have an i7 3820 + GTX 670 and am currently on Jinc 4 taps/Jinc 3 taps/Lanczos 4 taps. Thanks in advance! |
