What area of the game

Hello! I can't narrow down when it happened... but atleast starting from a few days ago, PPSSPP in retroarch (have tested on windows and android) runs at low fps (lower than half speed). I have tried default settings, clean installs, you name it. I will say that on IOS the last Retroarch build from 9/2 still works fine.

I took the core from the stable builds of retroarch and it also works fine on Windows and Android.
