They could all present different wheels, materials, complete rigs with seats or whatever they could think of, but the FFB itself as a function of the hardware and software would have to be standartized among all competitors (and then it would also be the same for all games).
That is quite possible, but I guess just not welcome for some reason or the other.
there's several reasons probably. I mean as good as Iracing and ACC (and even GT7) are, they aren't perfect. They still all take liberties with physical reality, and they each do things in slightly different ways. But even if a sim was theoretically "perfect," it would likely still be problematic to just lock in a given wheel configuration with no ability to adjust it. As a dev, you want to try and make the product as accessible as possible (assuming we're talking about any sort of mass market endeavor that is) and if you don't allow
any customizability you're invariably going to end up with a bunch of people who say your sim 's FF "sucks! Feels like crap! Is totally wrong! Completely un-useable!" etc etc, and the fear would be that that would get to be the accepted view of your product. Otoh, as soon as you
do allow some customizability - even if as the dev you state outright that certain settings are the "correct" ones - you're invariably going to end up with you-tubers and so forth who land on other settings that they say are "more realistic." It's sort of a no-win situation. But at least with options available individuals can try and arrive at their own happy place lol...
But also, it's important to remember that these are still products meant to appeal to a wide audience. I like realism and I want a good amount of it in my sim, but at the end of the day I'm still just a 58 year old guy sitting in a beach chair in my living room. I maybe don't necessarily want to feel
all the actual FF that a real driver of say a Group C car feels. Maybe I only want 60% of that workload. So there needs to be some way to adjust for that.
I'd be happy if devs would just put together more detailed instructions regarding what all the different settings actually do and how they relate to the real forces of a car's steering wheel rather than stuff like "Centering Spring --- Adjusts the centering spring effect"
