By noise floor are you talking about Trueforce vibrations? Like the vibrations are grainy and more noticeable but should be more subtle? For me, I feel like the wheel might be less accurate and less responsive. It might be in my head but I feel a difference and it's hard for me to pinpoint exactly what it is.
I think when I use drivehub it feels like the wheel is in compatibility mode g923 and not in pro mode if that make sense.
I'm afraid to update the wheel firmware because I don't think we can revert back if it's causing issues with drivehub.
