Princess Peach: Showtime! Review and FPS Test on Nintendo Switch 

And this is why Nintendo needs to release a patch for the game that fixes the framerate issues. It's not just the loading screen, it's also the cutscenes (like the costume transformation ones) that suffer from this. But given how Nintendo releases and patches most of their games nowdays, I won't be surprised if they abandoned this game at v1.0.0 with the messy framerates forever

I can personally forgive this problem since I think the game's conceptual and visual advantages are overwhelming, but yeah. I agree they should do the patch whenever they can, or at least try not to make the same mistake from next games.
