Media Framework in 4.11 Preview 8

Video that has been playing back at ~90fps for 3 months suddenly cant get about 44-45fps on 3 different machines after update to preview 8. We have tried downgrading the preview back to 7- but cannot seem to regain our 90fps, even in packaged builds (which seems ridiculous). We’re thinking a driver of sorts was updated but cant seem to find anything anywhere. Playback is fine in other software packages, so Im assuming it is not a Windows wide update.

Hello TheAdmiral,

This issue sounds quite particular, and I might need you to share a couple of your movie files so I can verify what you are reporting on my end. You machine is plenty strong, so the drop in FPS shouldn’t be a hardware/software issue.

Could you perhaps provide some screenshots of your FPS between the two engine versions as well?

Let me know if you have further questions.

Cheers,
