“Tires in rF2 are in some ways sublime. From tech side. What often lets down is how they are utilized. Code behind tires is a masterpiece on many fronts but for it to work tire has to be built with extreme care and has to have chassis that is flaw/bug free. You can have best possible tire on a car but if chassis/aero is screwed then no amount of greatness in them will save the car from being absolute shiet. This is a trade off that rF2 has. It can be truly amazing when you put enough time, care and science behind a project like car with lots of data, know-how and fine tuning. It is a sim that can't be rushed when making a car because if you rush your making process in others sims you risk making a average car instead of good or very good car, while in rF2 if you rush it you end up with absolute dog excrement of a car. Get one thing wrong like chassis flex/ultra flex and whole car will feel off, even tires won't behave correctly.”
This goes for pretty much everything, I feel. rF2 is a marvelous piece of coding, but to get it to work properly-... that is an enormous hassle. And that is why AC is more popular.
