well, that's testable -- plug the controller in and see if it feels any different
I didn't even think of that. You know, last night, when I was playing and it was bugging me, I did have it plugged in. The other day, when I first got the game, I didn't have it plugged in, but at the time I wasn't experiencing lag. Maybe it has something to do with the controller being charged while playing?
I can do more tests later. or tomorrow.
