We all know that Rockstar have recommended NOT installing the ‘play’ disk of GTA V to the Xbox 360 hard drive, due to texture and frame rate issues, but the guys over at Digital Foundry have discovered that if you install that same disc to a USB drive, then things are remarkably improved.
A 16GB drive seems to be the one of choice and cuts out alot of the popup which occurs when streaming straight from the disk itself.
Have a watch of the video below to see the difference.
