@FAlonso Please don't joke like that about me being physics guru. There are maybe five people in simracing that could be called so. These people could throw lectures on various aspects of vehicle dynamics on the spot, live, with many viewers. I could be the one who could give them good questions tho...
I don't need to be anywhere near AC forums again. And people who work on that sim doesn't need anybody to advice them. And neither do any other sim developers. iRacing, Kunos, Reiza, S397 too by now... they all have specialists and know things. It is easy for them to put out realistic simulation and they have decent platforms to do that. The difficult part for them is to adjust to their audience. Perhaps easy for iRacing as they just do whatever they want, literally no rules apply to them. It is definitely very hard for Kunos with so many users, very obviously since ACC for them it is crucial to be perceived by as many as possible players as very good sim, which they magically hit with AC1, rather than just simply trying to be most realistic. For Kunos it is constant experimenting about which shade of realism is most pleasing to their average user. Kunos are able to do very realistic simulation. Even if perhaps their physics engine has limits for simulating particular dynamics.
Reiza situation is similar. I think they inherited more limits from user base, than from physics engine.
After all, people don't need any physics gurus. People don't need to be told that their driving sucks. People don't need to know that they are too sleepy for a car with mega performance tires, with mega downforce and low tolerances for mistakes. They don't want to know about existance of driving dynamics which will kill their joy of drift wooohooo fun with car that is set up to be on rails. They don't want to know that they are in fact not 1s off pace from top drivers, but more like 4-5s off. People who tend to know little, also tend to want to know less - it is a law. But they do want to have fun and have good feelings.
In mmorpg game people accumulate experience and does quests, and this way they perceive themselves as improving. But they only learn game mechanics and only gets artificially unlocked to greater powers. In simracing people does develop true skill, but many people get demotivated to find themselves 4-5s off per lap for months. Fortunately and unfortunately there also are mechanics about the way simulation physics get arranged to have that 4-5s gap to shrink down to 1s and get a lot more people to have closer racing - it is called sharpness of grip, sudden changes of grip. What happens when you grow entire generation of FFB gamers by offering them very unsharpened physics for 8 years ? You get stuck with that. And the dark side of such unsharpened physics is that many of the car dynamics on the fine edge of the limits are gone, but thats not a problem for most people as long as physics aren't utterly absurd.
ACE maybe is on the good direction now, I don't know. If it is very likely there are tens of thousands people believing that it will come back to them, to please their feelings about themselves, all in disbelief, only able to put everything on the FFB.
But I don't know. It is not ACC. It is not just one car. However, there are certain small things that can be altered in minutes. And the only hard thing to do is the decision.
Sim developers has families. They have to pay taxes and want to eat. Maybe some also needs to buy new yacht, but that is different topic.
