Persona 5 [BLUS31604]

[Vimes]

I've observed that game is smoother but as a result tends to random stutter a lot e.g. rotating camera was a nightmare
Also, loading screens are longer and screen freezes but audio continues

(Note, this is on the 0.0.3-5805 build)

From what I can tell most of the stuttering is caused by the emulator compiling new shaders everytime it has to render something it hasn't encountered before. This drives the CPU up the wall and causes everything to lock up until it's done (usage goes up to 100%).
On my laptop with a skylake i7 (4 core) I get the have the same issue as you and the clock goes up as high as it can (~3.2 ghz).
On a desktop the issue isn't nearly as big, it's actually far more playable than before the rework.
The shaders are compiled before it has a chance to lock up and the framerate's up by 5-12 fps, although I've noticed that in the ingame engine cutscenes the audio tends to get desynched a bit.
