Second Pokémon Switch game I've played since Legends: Arceus.
Last Pokémon gen I played was VII or Sun/Moon.
I believe there are a few QoA features that can be implemented to bring the games performance up.
However the game plays well for the most part on my Switch Lite.
One area where thr performance went poor was in a large lake area and many water type Pokémon were spawning. My character was swimming amongst them but once I got to solid ground it began to improve.
