Mess up your game
From Glitches
From the game True Crime for the Nintendo Gamecube
Grab a fast car and drive all the way from one end of the map to the other on interstate 10. Don't stop for anything. When you reach the other side of the map, the game will freeze. From then on, the pop-up rate is horrendous and the game is really slowed down.
