For real man, I was playing my Steam copy of Oneechanbara Origin Last night. Runs at 720p 60fps on my Ally. It was a good time.
It's crazy though that people whine about the performance of handhelds when anyone who has one already knows that the trade off for portability is a performance hit.
No one who actually enjoys portable gaming is gonna care about the performance though as long as it is stable and playable.
