Persona 5 [BLUS31604]

I'm using a special build from a link and I have a some problem - I don't know why but game framerate is locked on 30 fps. In the game itself it is not a problem. The main problem is video cutscenes. They are should be played at 60 fps and at 30 they are very slow and the sound is very sluttering.
I tried to use framelimit "auto" and "60" (for both emulator and the game) - no luck, still 30 fps lock.
There is no such problem in main emulator (not special build).
Is there any solution?
