Recently switched to Windows 10 from 7 (clean install). Having a couple issues now. Overlay mode doesn't work too well now (GTX 950), it drops frames at random points for seemingly no reason, like 6-7 at a time. Perhaps every 10 minutes or so. Overlay mode worked flawlessly with Windows 7. D3D11 exclusive mode seems to work ok, however, if I hover over the MadVR seek bar, the queues empty and starts dropping frames. Move mouse away form the seek bar and playback returns to normal. Anyone else seen that? D3D11 windowed mode seems to be robust, but hovering over the MPC-HC seek bar I get 1 presentation glitch (better than frame drops)

If I disable DSR, use madVR's custom refresh rate tool + optimize, then it gets saved. Then, if I re-enable DSR (even without using it), then madVR's custom refresh rate disappears and DSR custom resolution appears. I wish there was a way to preserve optimization settings to quickly re-apply them. |

That explains why reducing the back porch (which reduces the blanking interval) gives me almost perfect 23.976 refresh. But in order to do this, I have to lower the total pixels on my TV to 1123, and that results in weird lines either at the top or bottom of the screen, which must be a result of the missing pixels. There doesn't seem to be any way to both get close to the exact refresh rate and avoid this problem. Is there something about plasma TVs that might cause this?

you are sending a digital signal so it doesn't matter if the display is a plasma or LCD the panel it self doesn't get this signal. so it comes down to the chip that get's the signal. and because you are talking about the perfect 23p refresh rate i recommend you to read again what you should try to achieve with a custom refresh rate because it is clearly not perfect 23p. |

Now I try to optimize the custom mode 23p. Select 23p, edit and then apply the EDID info. Now I can press the Optimize Button. Start a video with 23.976 fps and then I have this screen: https://ibb.co/goRmgk The i press Optimize and select the Optimize Pixel Clock #1 https://ibb.co/hiFe1k I select this profile, reboot the PC but when i start the video with 23.976 fps, I have always 1 frame repeat every 4.40 min. why? This is my setting https://ibb.co/jtxWE5 Where is my error? I have a nVidia 1070GTX GPU Thanks a lot Last edited by cyber201; 31st August 2017 at 15:18. Reason: remove image |

With my display and GPU every set of timings after the first optimization pass measured worse then the first one. The first optimization of CVT RB2 got me to an estimated 18h before a frame drop but subsequent optimizations have measured as bad as 10 minutes. I think exact change in timings for a particular fps is not an exact thing, which is why madVR has to re-measure and re-tune after the first time. Maybe let it play undisturbed for an hour or so as well, give madVR more time to get accurate measurement.

It is like the settings are not saved. If I try CVT RB1 or RB2, my TV screen is flickering. I must start whit EDID profile. |

Hmm, that sounds like a driver issue or something. It definitely will not be correct if madVR is not switching to the correct refresh rate. By different do do you mean by 0.002 Hz, 0.1 Hz, or 30 Hz?

Absolutely, you can always trust madVR.
madVR's choices are all decent options relative to the quality selected for luma doubling. If you have a little performance to spare, but not enough to go to medium for luma doubling, you can try to turn it up a little but it is not important.

My display is always 23.95055 Hz. What you mean "By different do do you mean by 0.002 Hz, 0.1 Hz, or 30 Hz?" ?? |
