Firemint has released an iPhone 4 update to its popular Real Racing game for the iPhone and iPod touch. Real Racing 1.22 features new graphics for the iPhone 4 Retina display with higher-resolution textures, more detailed car interiors, updated menus and improved graphical performance on the iPhone 4. The update also promises smoother graphics on iPhone 3GS and third-generation iPod touch devices through the use of anti-aliasing in iOS4. With this version Real Racing adds support for the iPhone 4 gyroscope to provide more responsive and accurate controls for iPhone 4 users in addition to accelerometer-based controls. iOS 4 Fast App Switching is also supported to allow users to exit the game and automatically pick up where they left off when returning to it. Real Racing 1.22 is available from the App Store for $5 and is a free update for existing users.
