The Switch is old hardware that was under-powered on release, therefore, I expect that I'm not going to be getting 60FPS.
Basically, it's down to expectations. The Switch is absolutely great at what it does, and I appreciate it for that reason alone. My expectations are greatly different compared to a gaming PC/PS5/etc.
My biggest gripes with Nintendo is the god awful way they handle people using their IP to make YouTube videos, etc.
You can't even compare an open market in which small teams have to cope with the myriad of possible configurations, ofthen lacking the technical skills for optimizing their software down to the bit with the supposedly top product of a trillion dollar company writing software for their own devices - and failing to make it decent.
