A pre-existing game might be one of the best to show off your soon-to-be brand new iPhone 4S’ power, if Firemint’s Real Racing 2 is in your collection. Real Racing 2 [$4.99] and Real Racing 2 HD [$6.99] are set to receive a free and new update that’ll add an extra layer of graphical goodness on top of their pre-existing sizzle, all in the service of harnessing the A5 chip. New dynamic shadows and lighting, increased polygon counts, reflections, and exposure effects are all being added in the game’s latest update, which should hit pretty soon.

And that’s not all — iOS 5 is coming and so are a handful of features to Real Racing 2 that revolve around Airplay support. With the update, you’ll be able to wirelessly stream the game’s content to your TV. Also, if you’ve got friends with the game and an iPhone 4S or an iPad 2, you’ll be able to play with them in split-screen. “Party Play” mode will allow up to 4 players to compete on the same screen, provided the host has Apple’s new hotnesses.

Firemint isn’t known for missing a hardware launch, so we didn’t expect any less. Still, this seems like an absolutely spectacular deal for current and new owners of the game. Real Racing 2 was great to begin with, and now it’ll look even sharper than ever.
