I've already beat God of War III once completely with no problems, and on my 2nd playthrough I've quickly ran into all the freezing issues that everyone is having here. Well at least for me after you kill Poseidon everything should run fine. No more problems. I think the game has trouble loading everything in beginning because of all the action thats going on plus considering the game loads everything while your still playing it probably causes the game to freeze. So check your HDD light on the PS3 and wait for it to slowdown in the beginning it should help cause once you reach the river styx everything runs perfectly.
