I'm still not getting the lag, but my buddy is, big time. I'm starting to get nervous for when it will hit me. Anyway, he emailed tech support and this is the response he got.. Pretty presumptuous of them to insinuate it's his ps3 that is the issue and not the game. I am also not sure why they would want him to delete the game data.. It's just going to have to reinstall anyway.
We are sorry to hear about the inconvenience you are encountering with your game. Your issue may be resolved if you clear your game cache on your PS3.
1. Problems may arise if you have been playing the game for an extended period of time. Let the system cool down, then try running the game.
2. Please make sure that you have the most recent update for your PS3 console.
3. Remove the game data from the Playstation 3 Hard Drive. Files in the Game Data Utility folder, are saved settings for a game (i.e., controller preferences, brightness settings, etc.). These steps will NOT delete your save games. To remove a game data file from the PLAYSTATION 3:
a. In the XMB home menu, go to (Game) > [Game Data Utility].
Important: Make sure you select [Game Data Utility]. Do NOT select [Saved Data Utility], as this will delete all of your saved games files.
b. Highlight the game data utility file (i.e., name of a particular game you have been playing) you wish to delete.
c. Press the button and select [Delete].
d. Highlight "Yes" and press the button to confirm the deletion.
e. A message indicating the file is being deleted will appear.
f. A "Delete completed." message will appear once the file has been successfully deleted.
4. Try running it from another console. If the game works properly on another system, you may want to contact Sony to find out more about getting your PlayStation 3 serviced. If the game fails to run on multiple consoles, contact our Technical Support representatives for further assistance.
Thank you for your time and patience!
