I have a radical setup and it is the best I have used so far.
AC "Lock to Horizon" set to OFF
RHM Pitch Filter set to 0% Min ANGLE set to 10
RHM Roll Filter set to 0% Min ANGLE set to 15
Everything else on 0
This locks your eyes to the car but allows them to stay on the horizon until the car rolls or pitches up to the Min Angles. This means you see/feel the car moving and can sense the bumps and curbs better, but your eyes remain focused in front. The biggest advantage I found was that in a crash you can still tell where you are instead of just having a jumbled mess of visuals.
