Love the game so far (sound, graphics), but it's very hard to play with Dualsense - do I have to do some tweaks?
I play on PC with dualsense, and it's amazing, IMO the absolute best driving game for controller, but you do need to get the right settings, it took me months to nail them all.
Difficulty:
Many types of car are fine with TC off, or on sport, but some really need it on comfort for best performance, and you can't set it per car or per category, so I leave it on comfort. ESP you absolutely cannot set to comfort, it will slow you down enormously. Sport seems to cause very little slowdown compared to off. IMO you definitely want counter steering assist off.
Controls:
There is a lot of room for personal preference, but I get pretty high up on leaderboards and have won many grand races with those settings. The obscurely named "dynamic max lock" appears to be sensitivity when counter steering. If you find the car over-correcting when you countersteer and going into a slide in the opposite direction, lower it. If you find you can't correct oversteer and it won't straighten up from a slide, increase it.
If you want to be really hard core, direct mode ultimately gives you the best control, but IMO it makes countersteering really difficult. It's worth trying sensitivity 100, I might have a go at increasing it from 80 myself now that I've become very comfortable with 80.
People go on about how good Forza is with controller, but with the above settings, I find Motorfest massively better than Forza, Forza just feels painfully sluggish to me now.
Oh, also, I've turned the trigger feedback down to zero. What they've done with the dualsense haptic trigger feedback for braking is really impressive, but I've found it makes me under-brake for corners and I do better with it turned off.
