Posted this in another thread, its basically some new support for the shoddy drivers that ms have released, adds things like profile etc, i've not tried it myself but after looking on a few 360 specific sites it looks like this is the business.
From the admin and developer:
The first and most abundant reason people are using these apposed to the microsoft drivers are deadzone support. Most hits from my website come from people searching for "Xbox 360 Deadzone". Below is a list of reasons to use opposed to Microsof Drivers.
Deadzone Support
Controller Remapping Click Here For picture
Early Rumble For non x-input games
Range Control
Analog axis and trigger sensitivity control
Guide button Lights up
Is open-sorce so it will always be able to add features down the road
Windows still detects it as a "controller"
Last but not least XBCD driver creator Redcl0ud has ControlMK (also made by Redcl0ud) to map keyboard keys to this gamepad.
ControlMK is great for Games Like: Far Cry, Battlefield 2, Half-Life, Doom 3,Call Of Duty 2, Splinter Cell: Pandora Tomorrow, Serious Sam 1 and 2, Unreal Tournament, Tomb Raider 3, Hitman 2, Close Combat: First to Fight, and many many more!!
