Where I live I'm pretty much never going to encounter PAL film content. It's either going to be film with a telecine to make it i60 which needs an IVTC, or true interlaced video content. IMHO, what would be nice would be user side options allowing some of the cadence patterns to be blocked in the IVTC routine, and some way to configure madVR so that it will attempt an IVTC and if the IVTC fails it will pass the footage to the video card driver for "video" deinterlacing. Currently it seems I have to disable automatic source type detection and force film for the IVTC routines in madVR to work, and if I play back true interlaced video content it's not going to be properly handled until I enable automatic source type detection again. |

You're right. It's the 3D features of D3D11.1 which are not supported on Vista. |

Those are not even in 7, aren't they?

The 2:2, 3:2 file is indeed soft telecine, 96.55% film according to dgindex.

EDIT: Would the repeat_first_flag or something else have an effect on hard telecined material? Switching to it reduce cadence breaks from about 1 per minute on average to 1 every 2.5-3 minutes.

I'm not saying that you should rip out the existing D3D9 functionality, but if supporting D3D11 would improve madVR in a meaningful way (e.g. 10-bit output) it's something to consider. |

I'd say a bigger problem with Direct3D 11 is graphics card support - for instance, only the GeForce GT 430 and up support D3D11. The first GeForce 4xx cards became available in April 2010 (whereas Vista dates back to January 30, 2007). Mind you that's mostly a reason to not rip out Direct3D 9 support.

Should FSE have higher rendering time than Windowed mode? I just got a Radeon HD7790 using the 13.12 drivers under Windows 7 (32-bit) with MPC-HC 1.71 that's what I'm seeing. In FSE I can barely keep the rendering time under 1/60th of a second if I crank up the madVR settings with all the driver video "enhancements" disabled. In Windowed mode I can use the max madVR settings and enable all of the video enhancements (except edge-enhancement) and still have a few ms of rendering time to spare.

@Stereodude
If you've set the number of video frames presented in advance too high, maybe. AMD cards behave better with low values like 6 to avoid DPC latency issues. If you are using a refresh rate higher than your video, FSE is slightly more intensive since it presents a frame every vsync interval, while Windowed mode only presents a single time for each video frame. If you've set Flush or Flush & Wait for any of the render steps, that will also increase render times and/or tendency for dropped frames quite a bit under heavy GPU load. Otherwise, ensure you are not forcing Anti-Aliasing, Anisotropic Filtering, VSync, etc globally under your GPU's 3D settings. Any globally forced settings will be detrimental to madVR performance under FSE. GPU video "enhancement" settings should also be left disabled if you are using madVR.

Most of the video driver "enhancement" algorithms only affect the image (and the rendering times) if you use either DXVA deinterlacing or DXVA scaling. Otherwise they should have no effect. |

I've got a AMD HD 6800 series (13.9 drivers). The following settings works perfectly on madVR (less than 10 delayed frames on 2 hours video and no dropped frames) : Render queue (CPU & GPU) : 12 Number of video frames presented in advance : 6 I disabled all "enhancements" together with IVTC processing in CCC and set the output to RGB 4:4:4 full range. Moreover, HW acceleration increase the redering time, see if it's enabled in MPC-HC > LAV video settings
