They said they have improved the physics from the Williams' game... so it should be a bit different I'd think (as would be all the table re-releases).
The problem is that the PS3 version of
Pinball Arcade is significantly laggier than the other versions of
Pinball Arcade. The flipper response is off by several frames (I'd estimate anywhere from 5 to 10), enough to be
visibly noticeable and a distraction to gameplay.
PS Vita--quick and responsive.
Android--quick and responsive.
Xbox 360--quick and responsive.
PS3--slow and laggy.
I've also got several other pinball games which I play on the same TV (Zen Pinball for PS3, Marvel Pinball for PS3, Pinball Hall of Fame: The Williams Collection for Wii), and there's no perceptible lag. My friend also has Zen Pinball & Marvel Pinball on PS3, and Pinball FX 2 on Xbox 360, and there are no problems with those games. He actually switched back and forth between the PS3 & Xbox 360 versions of Pinball Arcade on the same TV, and the difference was unmistakable.
