What's the set FPS for a game?

Example game: Dying Light: Definitive Edition // Is it 30fps on Switch? Is it 60fps when docked? Is it 30fps on Xbox One? What about One X? Series X?

Yeah, I can just google it to read some random dudes reddit post from 2 years ago, or dig through a review but if it’s feasable to somehow have this information on DekuDeals it would be extremely beneficial for people to see & know before they buy the game
