Some shot of reality for some users.
Its about how good the engine is, and how smart they devs are at optimisation.
Look at Fortnite on the iPhoneX, thats crazy how good it looks for a mobile game.
Digital Foundry compaired the Iphone X version to the Xbox One X.
This isnt a "switch is more powerfull than people think" moment, its a ARK devs use a bad engine/cant optimis their games thingy.
