Digital Foundry: How to install GTA V's play disc for a smoother ride
Digital Foundry has discovered a workaround to the Grand Theft Auto 5 bug that causes lag when the second disc is installed to an Xbox 360 console.
The video above illustrates the problem: On the left is the games opening running on a console with the game installed to the internal hard drive. On the right is a console operating with Digital Foundrys solution to the problem: Install the first disc to the hard drive as directed, but install the second disc to a USB thumb drive.
Results, says Digital Foundry, will depend on the USB drives speed.
Update: While some users reported success with an 8GB USB drive, it is recommended to use a 16GB drive if possible.
