1: FFB must feel different for each car, in terms of strength as well as in terms of amount of information coming through, that is called realism and derives directly from the geometry of the steering rack, the tires and weight distribution of the cars. The force calculations are correct and not “fundamentally broken”. (period)
2: There might or might not be bugs with the amplification of these forces for certain FFB wheels. For SMS to investigate, they need specifics - ideally a video with the telemetry screen active. Yes of course it’s not a precondition, but if you don’t - you can’t really be expecting to get other users here to understand you or help to investigate. SMS loves to discuss technicalities with players, but only if they respect basics of the code of conduct for online conversations and have something substantial to say about a topic.
3: FFB profiles Immersive and Informative were specifically created for low and mid end wheels, with Immersive featuring the SoP simulation many people love. If you are not sure if you have a high end wheel....you don’t have one! These two profiles have a autoscaler for the FFB that works really well, people mostly don’t know about it and are not driving long enough (2-3 laps) for the scaler to settle in on a reasonable value. Instead they use RAW (which doesn’t autoscale) with absolutely wonky slider settings “from the internet” and then complain that they have to adjust FFB strength for each car, having “inconsistencies” and ofc the inevitable “physics are s***!!!!1!1!1!1” nonsense.
