One of the reasons I choose the Pro over the Sport was because in all the marketing leading up to the SC2 release and for a long time after, features charts said that the SC2 Pro would have a “non-linear force saturation” feature.
I’m assuming “non-linear force saturation” is basically a way to change the linearity of the overall forces’ output. I think at least a basic version of this feature would be a huge plus because lots of games/sims don’t include a way to adjust this and it’s a very important option to adjust in my opinion (along with the other features/filters available). I would love to be able to adjust the linearity for some games/cars because many games/cars have the FFB loading up way too much, too suddenly rather than gradually loading up. It’s probably an issue with the sims’ physics but that’s another discussion.
I really think this is needed at least in a very basic version (linearity of all/overall forces).
