If you lag that badly in Smash when you play while downloading then guess what? You're probably also lagging badly in Mario Kart 8. It's people like that who piss me off because they're largely the ones who cause the item wheel to lag, which causes me to miss shortcuts, get hit by red shells I could've blocked, and more just because the item wheel has a like 5 second delay. Just because there's no input lag does not mean that you aren't lagging up the room like mad.
