It it my understanding, (I could be wrong) that any installed game required the DISK, to be able to play. As this would prevent from passing a single game through the neighborhood. The load times are long in DKS, even with an installed game.
Ya.. I already said I expected it to be required for verification.
But installing a game is supposed to speed up game performance by allowing the Xbox to run the game from the HDD, using the DVD just to verify it's legitimate. Otherwise, what is the purpose of doing the install?
In this case, it seems to have no performance increase so I think it is still running to game directly from the DVD.
