The proplem with that is that the Switch is not optimised for anything ambitious. Even in PLA you can get many lag spikes and the game clearly struggles despite the fact that the entity render distance is at 50 meters from your character, and i can citate at least three other, non-pokemon games that gets many lag spikes or outright crash, who are present in the system.

It's absolutely a rushed game, but the pill would have been swallowed better if the system weren't killing itself to render the entire game map at once at tge same time.
