To explain better the difference between HID and XID.
HID: The game using the CPU simulate the FFD (Force Feedback) and send the commands to Wheel (well like "push to right or left"... or anything else).
XID: The wheel uses profiles previous created... so no CPU is used to simulate anything.
It's not hard to understand why the XID is a bad choice in a simulation game... because there are no different response based in user actions into the game.... the game no simulate what the FFD will be... the wheel will always uses a predefined profile.
So in Forza if a different action happen in the game the FFD didn't change... in PS3 and PC you receive a different FFD based in what happen in the game.
The bad part of HID is that you need to use CPU resources to that... the XID free up the CPU at cost of less real life simulation.
