I never hear of nintendo patches. But honestly i also dont hear much of nintendo games having performance issues. So dont know if this is something that can be waited to be fixed ir call it a loss cause.
Also i think most of the backlash is that the media is begging for a new console. I think most are saying the switch is showing its age and will focus on any game showing issues. Also a game that looks like pokemon does has no excuse performing so bad.
It takes genuine talent to see greatness in yourself despite your absence of genuine talent.
