Story Of Seasons lag drop fps issue

I want to play this game with 100% full speed, but it is lag or drop fps in some areas, average 50% speed with 10 fps. Is this game issue ? Because I can play full speed PKM US so I don’t think my pc spec is not enough. How I can fix this issue ? Thanks so much !

We’ve been having frame drops with Trio of Towns as well.

hard to tell without knowing your system specs or your citra settings.
