Should Nintendo use Unreal Engine 4 and Unity in more of their games?

I don't know one single game which uses UE4 and runs in 60fps or even stabile 30fps on Switch. Abzu, Snake Pass, Octopath Traveler had bad and countless framerate droppings, Rime was almost unplayable. So.... no. If Nintendo don't get their Yoshi game run in constant 60fps at 576p, I think it's almost impossible to use this engine properly on Switch.
