No you just expect it from GameFreak.
Hell Ark just got a massive update to where the game runs and looks great for the switch. Dying Light 1 is way more complex and detailed than the new pokemon games and runs at a rock solid 30fps. Hell the Xenoblade series looks and runs miles better and XC3 just came out.
Has zero to do with the hardware and has everything to do with releasing yearly pokemon games where the dev team at most has a year and half to work on them (depending the team).
Sucks since there is a lot of things don't correctly IMO but the graphic's and performance is just bad.
On another note: Seems there is also a memory leak issue, if you play the game for awhile make sure to reset it every few hours.
