you mean for the wheel? Theres two options
Misc>Analogue steer smooth
Controls> steer compensate
The first one slows down your inputs and makes it smoother, the second one makes the virtual wheel more like the inputs on your physical wheel. turn them both down to zero then move them up to how much you preffer. i use about 02 compensate and no steer smooth. But i usually adjust depending on the track/car. Single seaters i don't use either but in GTR's i use a bit more compensate.
