Unlikely as the game only uses the CD drive on startup, it doesn't use it again and again throughout the game. The game content loads from the HD, the CD is used to validate the copy in most cases. With the present CD/DVD speeds I don't think there is any need to use a no-cd hack. If the game is slow, try adding more RAM, upgrading other hardware or reducing memory usage in the game. A no-cd hack IS piracy, by using it you agree with the illegal practice(s) even if you do have a legal copy. That's just my feelings on it.
