Reclock vs Madvr/MPCHC refresh rate disparity

[kiwijunglist]

Hi

My display is set to change to 23p refresh rate with 23.976 fps movies.

I start playing a 23.976fps movie...

MadVR reports refresh rate is 23.976
AMD Catalyst Control Centre reports refresh rate is 23.9741
Reclock reports media fps rate is 23.976
Reclock reports video hardware refresh rate is 24hz
Reclcok (?incorrectly) increases playback to 24

Sorry, that a pirated download. We can't assist with such issues. God knows how the file was compressed, which flags were used, which settings...

ahh thanks, I will use a different test video.

I tried a few additional steps for diagnosis/trouble shooting.

1) Set display refresh rate to 23.976 before playing back a video and reclock still reports 24hz

2) Changed reclock video settings to
Detect Monitor: Force primary (I'm only using a single monitor anyway)
Hardware interface: DirectDraw
Reclock still reports 24hz display

3) Change reclock video setting -> hardware interface to Direct3D (Video fails to start, is this the issue?)

This is a known problem with the combination of ReClock+madVR full screen exclusive in Windows 10 Creators Update. MS did something that messed up ReClock's ability to get the refresh rate. For now you can use windowed mode, and first reset the timings database in ReClock's settings just in case.
