Every so often you may encounter a slow down on graphics and game play. If you have been playing for less than three hours and see the "Loading" text, release your controller for faster loads. If you have been playing for over three hours and the game play slows down, save and reboot your Xbox 360. This is because the Xbox 360 does not have an efficient way of clearing its memory for new information. Once the memory is saturated, the "lagging" game play happens. Because Mass Effect is so massive and everything is unique, it uses all of the available memory.
