I started playing this game recently on PC. I have an high end system and run at about 250fps locked. I'm also using a dualsense.
And I agree, steering feels delayed even at 250fps!!. But one thing that helped me was reducing the wheel rotation. I leave everything else default.
220° works for me very well.
I also change the default deadzone from 0.1 to 0 on the config files.
Adaptive triggers are also useless, way to slow to provide feedback. Even if you acelerate very slowly and smoothly can still spins before the trigger gets harder.
Brakes are ok, u can actually feel it before you lock the wheels
