I just got this game last night and at first I played it without installing it. The opening cinematic ran smoothly with no pausing. I saw the message that said it works better to install, so I quit out and installed Disc 1 to the HDD. After that, all the cinematics and load times were terrible. The opening cinematic started pausing after the guy with arrows was done. It just got worse as it played. It would pause for 1 second every 4-5 seconds towards the end of the scene. I tried the Arena and the opening cinematic there paused a lot as well. Starting a new game, the load times were 3-4 times longer and even the music skipped like an old record.
I eventually uninstalled the game from the HDD, and everything went back to running smoothly. I would like to install it as it saves on the wear and tear of my 6 year old XBox. I install all of the games I play on a regular basis and have not had issues with the others (i.e. - Skyrim, Revelations). Has anyone else experienced these issues? Anyone know how to work around it?
