so there are 2 possibilities: madVR has a bug and bilinear is used when DXVA scaling is used. or EVR is not using DXVA scaling. edit: looks like it is a bug in madVR. I did a small test look here: http://abload.de/img/evrsplita9ubm.png this is EVR with split demo mode. would be nice if someone can check madVR again with this sample and see if it is bilinear for you too. after that I will create a bug entry in the bug tracker.

can you please show what your results with madVr if madVR uses biliniear for you too it is very clear a bug in madVR.
both EVR in MPC-HC and windows media player don't use bilinear for me but madVR with dxva does. Last edited by huhn; 15th February 2015 at 15:29. |

on the left DXVA scaling with video enhancements off, on the right DXVA scaling with video enhancements on. The "bug" is probably as simple as madVR disabling video enhancements on your system, but not for some other people and that's the reason you get different results - different driver's settings. |

so you didn't get bilinear with DXVA in madVR using a AMD card? this would mean it is a bug my side which i'm totally fine with. |

I have UFC fight pass and the "HD" stream is "720p" (which I'd be okay with) if there weren't so much aliasing (jaggies). It's crazy. I started playing around with the HTML to see if I could stream it through to MPC-HC (and madvr). Does such a product exist to push a videostream to MPC-HC? Perhaps that would be a way to leverage mad-vr to improve most of the highly compressed web-content |

EVR: DXVA: LanczosAR: Bilinear: EVR-disabled RGB: I am not sure what this means Last edited by detmek; 15th February 2015 at 23:31. |

Look at the screen closely and you'll know that there is a pixel shift to left upper in EVR (DXVA scaling). It looks like a genuine bug of EVR and it seems to cause the problem with the dxva scaling of madVR. There is a same shift in EVR and DXVA2 resizer. That's the main reason why I consider both are same.
BTW, the screenshots are from iGPU? EVR and DXVA screenshots look different. I'm not sure it's because both are using different resizers or additional processing of madVR affects the result. Would you try the sample with potplayer? I get the exactly same result with EVR and DXVA2 scaling with HD7850 at least. Last edited by sheppaul; 16th February 2015 at 00:49. |

On my GPU, EVR-CP(set to bilinear) & madvr DXVA2 scaling looks the same. Plain EVR isn't.
BTW, using NNEDI3 on that test sample, doubling @ 16 neurons + quadrupling @ 16 neurons + jinc3ar image scaling give me better result than increasing the neurons further with or without quadrupling. And here I thought higher NNEDI3 neurons is better. Or is it safe to say that it depends on what source video you're playing? Like anime & live(or should I say real life?) video for example.

It's iGPU, I don't have discrete GPU. Here are screenshots with PotP. I used default settings, only changing renders. EVR: madVR DXVA: madVR Bilinear: EVR does use DXVA scalling as I got same bug and same difference in sharpness. Maybe a driver problem. Last edited by detmek; 16th February 2015 at 11:12. |
