I have all settings exactly the same on Vista 32 bit and W7 64 bit and can't understand why this is happening.

On W7 the first ~15 degrees on the G25 feels really light with little or no feel from the tyres resulting in a lot of oversteering. So to compensate I rase the FF level which means some oversteering in the first 15 degree range and a LOT of understeering thereafter.

On vista same car/track/setup it feels right as I begin to turn the wheel every degree is giving me FF from the tyres...any clues guy's/gals?

I have the same problem with my logitech momo racing

hmm, almost sound like if the profiler contains the information for the G27's deadzone and sends that information to the other wheels too by accident..

Hm.. I thought it was in Vista aswell, but can't remember. The first few degrees I feel nothing, in most/all games.
