PS5: Vague center steering with Thrustmaster T300

I have the same wheel and have also noticed there is a bit of a soft/slow response area in the straight ahead position, it’s just like driving a car from the 1950s/1960s before rack and pinion steering came in! You could move the steering wheel left and right about an inch or so and nothing would happen, a bit like that. It would be nice if the response was a bit crisper on tarmac, as you say, it doesn’t do it in GT7.
