1. Brand new Force Feedback (Target release = June 2021) We have been working hard on a complete rework of our FFB, which we are all looking forward to sharing with you. We know FFB is a sensitive subject for many simracers and we want to properly explain why we think this was the right way to go and how we went about building the new system up from scratch. We hope everyone will be as excited as we are about the major improvements we have made here! This project was initiated after taking stock of the current FFB situation. As car physics were being developed, the amount of details going in that work has been shadowed by our FFB, doing it no justice. A list of issues was put together, our FFB code was analyzed, flaws were discovered and the whole thing was redesigned and rebuilt. Old FFB: Steering geometry of the car is ignored, resulting in little differences in FFB between cars. It results in the steering torques being wrong, as they depend only on tyre forces rather than the actual characteristics of the car Lack of longitudinal tyre forces Lack of gyroscopic forces from the tyres The tyre forces from physics are badly translated into FFB torque Tyre contact patch movement is ignored, no dynamic change while driving Too many sliders in the FFB options menu, some of them making promises the FFB could not deliver New FFB: Steering geometry is used: much more uniqueness between cars, the resulting steering torques have real meaning All tyre forces are taken into account Gyroscopic effects of tyres taken into account 100% Physics-based calculations Tyre contact patch movement is used: much more dynamic feel while driving Only crucial settings to adjust the FFB to the various steering wheels Source - https://forum.sector3studios.com/index.php?threads/may-2021-dev-notes.16906/#post-222103
