Something is up with it, I don't care what anyone says. All you need to do is go to the Replay Mode or Leaderboards and scroll down. It is choppy and laggy as fuck, reloading constantly, whereas in Super it just scrolled down smooth as butter. Some shit got fucked up in there somehow.
Also the game is dropping a ton more inputs than it did in Super. I am getting real tired of being full screen, double-tapping fierce punch, and seeing Sim just standing there doing nothing. I can deal with sluggishness, lag spikes, and all that shit, but dropped inputs make me rage like crazy.
