The physics are completely overhauled, whomever that poster is referring to they don't seem to have a clue what they're talking about. From windows central.
How does Forza Motorsport (2023) feel to play? Well, it feels incredible. This is the most refined, responsive, and consistent handling I have ever experienced in a racing game, and it forced me to look at each car as if I was actually driving it, to not just master each vehicle but also to learn every corner and segment of the tracks. It's genuinely an awesome driving experience, which should be at the core of any racing game worth its salt.
