I just noticed when I play my Gears 3 xgd3 even though the game is installed on the hard drive it still spins up the disc and sound like it's playing it from the disc. I'm on a path liteon with LT 1.91. When i hit Y to see game details even the xbox says it's installed. I'm deleting it and reinstalling it now. Just wondering if anyone else has seen this modded or stock.
