Pokémon Scarlet/Violet has been filled to the brim with bugs and game-related issues. Although Nintendo initially claimed to have received no feedback on the technical state, they have now released a new one (Version 1.1.0) and say the following about the update:

“We are aware that players may encounter issues that affect the games’ performance. Our goal is always to give players a positive experience with our games, and we apologize for the inconvenience. We take the feedback from players seriously and are working on improvements to the games.”

If the game is more playable now or if it is only until the next patch they will address all the perfomance issues remains to be seen.
