If it's like the demo, then it shouldn't be THAT bad. It mostly lags when you're selecting your move and the camera focuses on too many things, when the pokemon do their moves it runs fine for some weird reason.
Besides, it can't get any worse that Hyrule Warriors 3D. Nothing runs smoothly when playing it on old 3DSs, unlike SuMo.
True, and I still enjoyed Hyrule warriors on 3ds.
I can tell you from first-hand experience that it is playable but the frame drops are serious during battles with more than 2 Pokémon on the field. Especially if the background is very scenic.
Some move animations also significantly slow down your frame-rate (I once had a Electro Ball Pikachu almost freeze my screen for a second during a very scenic battle.)
The camera minigame also can be pretty laggy.
PS: I'm playing Moon on an old 3DS XL.
Ok thats good to know. I still don't want to update my system, since I love my Blue XL with Xerneas and Yvaltl on it... but its not a deal breaker right?
