After the Orange Box was released on PS3 there were clearly some frame rate issues within the game. When there were fast moving scenes in an open world, the frame rate issues were noticeable.
Orange Box fans worry no more for patch 1.10 has been released by Valve. If your PS3 is internet enabled the patch will show up automatically when you start playing the game.
Apparently, the patch also fixes Team Fortress 2’s slow connection as well. No word yet on what the 128MB patch that has also been released for the Orange Box contains.
