Just as you were thinking Apple's 64-bit A7 processor wouldn't get any use for a while, Chair Entertainment has announced its latest Infinity Blade game, optimised for 64-bit processing.

Infinity Blade III, the third and final chapter in the Apple-only trilogy, is available now on iTunes for £5 for iPhone and iPad. But it's the iPhone part that interests us. The game is built with the iPhone 5S A7 processor in mind and takes advantage of its new 64-bit architecture. Although it will still work on any Apple device with iOS 6 and above.

The game has new rendering effects like depth of field, blur and full-screen vignettes. All of which should looking stunning and run smoothly on the iPhone 5S. It also includes a bonus animated "Infinity Blade: Origins" short film directed by Ben Hibon.

The 64-bit A7 processor has 56 times the graphical performance of the original iPhone and 40 times its CPU abilities. That should make for a seamless gaming experience when playing Infinity Blade III.
