Apple has publicly released the Snow Leopard Graphics Update that was seeded to developers earlier this month. The Snow Leopard Graphics Update contains stability and performance fixes for graphics applications and games, including addressing the following issues:

- Addresses frame rate issues occurring in Portal and Team Fortress 2 by Valve, on iMac (Late 2009 and Mid 2010), Mac mini (Early 2009 and Mid 2010), Mac Pro (Early 2009), MacBook (Early 2009 and Mid 2010) and MacBook Pro (15-inch, Mid 2010) or MacBook Pro (17-inch, Mid 2010) models.

- Resolves an issue that could cause Aperture 3, or StarCraft II by Blizzard, to unexpectedly quit or become unresponsive.

- Resolves an image corruption issue that may occur when disconnecting and reconnecting external displays while the system is running.

The software appears to correct Snow Leopard performance issues brought to light by Valve.
