Does the display refresh rate indicator in the OSD show correct information? Does it behave differently to 0.12? I've tried CoreAVC, DivX, MPC-HC internal decoder and ffdshow. None of these decoders show that problem for me. Which decoder are you using? Can you please make sure that you have the latest version of that decoder installed? See here: http://msdn.microsoft.com/en-us/libr...8VS.85%29.aspx I'd say it's probably the combined amount of GPU RAM + AGP/PCIe memory or something like that. It's definitely not system RAM. Quote:

That said, in windowed mode rendering and presentation does fight with each other. So it's possible that if rendering blocks the GPU too long, madVR might not be able to present the next frame soon enough, which would result in a dropped frame. This problem will go away in fullscreen exclusive mode, and hopefully also in Aero when I implement a special rendering path for it. |

Could the difference I'm seeing be related to me owning an older GPU? My 7800GTX 512MB was from before the era of unified shaders which began with the 8800GTX. Would that contribute to this problem? Quote:

That's why I didn't call it "available GPU memory". It is what it is. And it was useful for me in finding a GPU memory leak, which 0.12 was suffering from. |

madVR 0.13 gives a great improvment. Thx, madshi.
One question: It seems the current madVR does not support (If I was not wrong) interlaced video. Have you schduled for support of interlaced video? Edit: Yes I'm wrong. madVR supports interlaced video. But the compatibilities currently are not goog enough. May the culprit is decoder or some other stuff.

0.13 is no longer smooth for me with Bicubic75 chroma on bluray video with a 9400M.
Madvr reports no dropped frames though max rendering time was around 48ms and frame time is 41ms. Average rendering is 28ms, in 0.12 this was enough to be 100% smooth as long as the HUD was turned off. |

Madshi,
I am now using the Arcsoft decoder and .013 works well. I was using the Nvidia Purevideo decoder prior and all worked fine. Evidently Purevideo and .013 don't get along. Is there a fix in the works for this? MAK |

Madshi just one small issue. For example when playing 24fps blu-ray, and when I double click mpc-hc window to resize to fullscreen, or go back to windowed mode, instead of the small images being made fullscreen immediately, it seems to go through a two phase resize process where it looks like its scaled horizontally to fill the screen first, then like 0.2 of a second later, it fills the screen vertically.
Just a small niggle, but it looks kind of strange when the image is the wrong aspect ratio for that split second :P |

After playing around with power schemes, turning reclock on and off, trying another decoder, and generally having no luck, I believe I have found the issue. It appears that if I make the HDTV primary monitor, then disable the desktop monitor, playback of 23.976 material at 24Hz with Reclock is perfect with FFdshow/Reclock/MPC-HC/madVR (defaults w/3Dlut). No stuttering and no dropped frames. Quite stunning, really.
As and aside, I also discovered that with Aero on, EVR-CP exhibits the same problem as madVR in the dual-mon setup (desktop primary @ 60Hz, playback secondary @ 24Hz). With Aero OFF, EVR-CP works great with this setup. |

that's w/ Reclock in auto(24fps) mode + CoreAVC CUDA, ffdshow audio+video running avisynth/winamp2 plugins. I've got a 3.5Ghz Q9450 and 2GB of PC8500 DDR2 running on XP SP3 w/o a pagefile. actually it only happens w/ the debug version, no garbage video w/ the regular distribution. using the latest CoreAVC CUDA for decoding + ffdshow post-processing.

I tried quickly the last version of madvr and indeed it is quite great and interesting. The last blocking point for me it's the missing subtitle pin renderer.
I know you was searching information about it and how implement it. I Hope you find them! Regards. |

I have some videos that don't have a 1:1 sample AR, but madVR doesn't stretch them as other renderers do.
The videos are large, maybe I can cut out some small piece if you don't already know what's wrong. Last edited by ajp_anton; 31st May 2010 at 22:58. |

Madshi you're a genius ! Tearing at 23.976/24.000hz is completly gone for me (Win XP SP3 -> so no Aero, ATi 4770), i didn't had time to check the new version more deeply, but fixing the tearing issue is a *big* step imho and if i find the time i will try to switch to madvr full time now - thank you very much for your ongoing support madshi !

I need samples. The more the merrier. The samples can be very short, they just need to be long enough so that I can reproduce the wrong AR. Usually 5-10MB should already be long enough. Please upload samples only if VMR9 and EVR show AR right and madVR shows it wrong. Thanks!
