Throttle is Not Linear/Is Unresponsive at Certain Percentages

Same, today is the first time I've experienced it, PS4 Pro, in player career, using Visa RB and Michael Schumacher, started in race 4 and still going on race 6, there is a serious lag from input and sound too, from both acceleration and braking.
I've not got a huge issue in racing with it, as the sound is the main thing and its more an irritation as it can be distracting, the power itself isn't such a big lag, but still noticeable.
