Updates to Sonic Generations have been released. The updates will be applied automatically when your Steam client is restarted. The major changes include:

- USA flag is now correctly displayed in Online Mode.
- Fixed an issue where the Shop menu would become unresponsive at low frame rates.
- More accurate timing clock to 60Hz—may fix some issues with fluctuant frame rates.
- Updated default keyboard layout.
- Keyboard controls now correctly support drift.
- Screen display has been sharpened when AA is disabled.

Notes:
- Users of NVIDIA Optimus graphics cards may experience an issue where the Configuration Tool fails to detect the Optimus card. NVIDIA are working on fixing the problem, and will get an update out shortly, during the next driver release window.
