Kingdom Hearts HD 2.5 Remix [BLES02070]

With the latest versions of rpcs3, the last problem at the beginning of the tutorial of kingdom hearts 2 final mix I reported seems solved, but now occurs another problem: while I'm walking the game runs more or less well, but when I start to attack the fps decrease very much and I can't even do the second blow of the combo. I've already finished the game some months ago, but there wasn't this problem. Can you solve, please? The rpcs3 version is v0.0.6-7981 Alpha [2019-04-14]
