I've driven both and I can say AC and LFS is probably on the same level as 2 of the most intuitive sims I've ever played, but they do it differently.
LFS to me excels in translating that "rubber meets tarmac" feel when you are on the limits of grip and countersteering behaviour is very natural.
AC feels mushier and the sense of grip is a bit off, but you get excellent sense of weight transfer during braking and steady state cornering. Countersteering behaviour is a bit odd in my opinion (feels a bit laggy). But the road feel due to laser scanned tracks is the best I have ever felt.
As for setups, in AC road cars are limited things in things you can do. Race cars you can tune a lot more. I haven't been messing around with tuning that much though so I'm not that qualified to talk about it. Unfortunately, tyre temperatures are not yet working properly atm so it's behind LFS in that respect.
I use a Logitech G25, here are my settings:
- Profiler strength 107%, all others 0%, 900 degree rotation
- In game Gain variable (80-90 for Formulas, ~100 for GT cars, 110-120 for road cars)
- Minimum force 10%
- All other effects 0%
- Brake gamma 2.10 (can't remember exactly, but it's the stock value)
- Also don't forget to calibrate the wheel in game
If you download the FFB Clip app it gives more precise Gain numbers than the in-game pedals app, but those numbers I give are usually around the correct ballpark.
Initially AC also feels like driving on ice to me (even more so than Gran Turismo
). But then I understand that it's because the wheel FFB purely only translates steering forces in real life. Most other sims adds in damping and friction effects to make the steering "heavier" and substitute for the feeling of grip you get in real life from g-forces. If you don't believe me, next time you take a high speed corner in real life imagine the g-forces are not there. The steering feel actually communicates little of the feeling of grip (probably only around 25%).
Once you get used to this and adjust your mind accordingly, you will see that cornering grip and speeds in AC are pretty accurate. I prefer a bit of damping in sims myself, but unfortunately that's how Kunos decides to program AC's FFB...
