| Summary | 0000721: On 540hz monitors (but not 240hz) MadVR stutters for several seconds after opening a video | ||||
| Description | I'm sure it's not a priority, but just thought I'd say for information's purposes that MadVR has a bug on ultra-high-framerate monitors. It worked well on my ol' 240hz display except for the occasional hang when I would drag it to a different refresh rate display. But MadVR doesn't like the new 540hz panel. On 540hz, playing a video: first 1sec of playback: normal playback 2sec-6sec: stuttering playback, MadVR statistics show "display" Hz incorrectly fluctuating from 100~180Hz 7sec-infinity: normal playback Latest Win11 update, RTX 4090, latest MadVR beta (but also happens on the stable release), happens on any given LAV decoder setting Happens on MPC-HC or MPC-BE with MadVR enabled Doesn't happen with MPC video renderer enabled Also happens when all monitors besides the 540hz one are off, so it's not a mixed refresh rate problem | ||||

It's possible that madVR's VSync logic is confused by the extremely high frame rate. Unfortunately it will be hard for me to fix this without having a monitor myself that can go as high. And I currently don't really have plans to buy such a monitor (because I have no real use for it). |

happens at 240 too. |

Ah - after looking at MadVR stats it does indeed happen at 240hz as Huhn says, just not as deeply (240hz > 200hz instead of 540hz > 100hz) so it's harder to see |

The highest my monitors can do here is 120. |
