This is an amended copy of a post @Niels Heusinkveld made in Reiza 51, which is relevant to all AMS users. Follows: What's new in AMS? So we did a few things that affect the FFB positively (we'll get into possible negatives later ) - Physics run at 720hz instead of 360, tire / road contacts are more precise and 'more often' - FFB is no longer limited by framerate or a maximum of 90hz, we fix the value at 720, 360, 240, adjustable in the controller.ini - We read the wheel position at 500hz instead of ~110hz, so tiny fast changes in wheel position (also the result of the FFB 'turning your wheel!) get put back into the physics engine more often How does the FFB get calculated? There are 2 parts to the FFB. The main steering forces come from the RealFeel plugin. On top of that there are Off, Low, Medium, High and Full settings. So in short this comes to: Part1: 'fake' effects - LOW (now PURE 360 hz): Realfeel forces only - PURE 180 hz: Realfeel forces only, but at half the rate - MEDIUM (now PURE + EFFECTS 1): + damping, friction, kerb 'pull', kerb 'shake', jolts from impacts at 180 hz - HIGH (now PURE + EFFECTS 2): +brake pedal steering vibration, at 180hz - FULL (now PURE + EFFECTS 3): + engine RPM vibration, car speed vibration, at 180hz. The controller.ini parameters do *everything* with these extra settings. You can run PURE + EFFECTS 3 ffb but have all the effects set to do nothing in the INI, and you won't feel them! These effects can be updated up to 720hz depending on your controller.ini setting. Part 2: RealFeel effects We still use the RealFeel plugin, only now it is not limited to the framerate and we increased the plugin rate to 360hz. This is the.. name says it .. *real*, or "PURE" part of the force feedback: tire contact patch forces push or pull the suspension steering arm and this force is sent to your wheel. Each car has its own entry in the RealFeelPlugin.ini file where the 'clipping force' is set (MaxForceAtSteeringRack) - that is the peak steering force for that car (negative or positive relating to the suspension layout). You can edit these values to se it lower then the absolute peak force (ex -4000 when the actual peak steering rack force on a given car is -5000, or 1500 when the actual peak is 2500), your FFB strength will be scaled accordingly & forces beyond that value will be "clipped". All our default realfeel values are set with 20-30% of clipping, as otherwise FFB can be quite light under lower loads with the average steering wheel. If you have a stronger wheel, you may want to reduce or eliminate the clipping for each car by increasing its respective MaxForceAtSteeringRack. There is also a setting "SmoothingLevel" which, now that we get a lot more samples, can be enabled without causing a lot of lag. Previously, at 90hz FFB, 10 frames of smoothing would be 0.1 second. Now at say 360hz, 10 frames of smoothing would only take 0.03 seconds. By default we use 2-4 depending on the car. What does REIZA have to do to AMS FFB: 1) Fix a few remaining issues: - When pressing Replay, FFB should not be active - When paused, the FFB should not be active What should be so new and different and better about this new FFB stuff then? When working as it should, increased physics rate means the sim calculates the forces on the tires more often. Going over a kerbstone at 200km/h it will 'see' more of the kerbstone ups and downs and transmit them to the force feedback. The increased rate force feedback also reports these updates to your wheel. You should feel the 'road texture' (a constant slight noise on most tracks) very subtly and taking a kerb at 50km/h will feel more clearly different from taking it at 250km/h. Previously the limited rate would have meant above, say, 125km/h the kerb wouldn't feel any 'different' anymore. How to get he most 'pure' FFB feel: - Set FFB effects to 'PURE 360 hz' - If you have a strong wheel, enable some 'always on' damping on the wheel software, you certainly need it, but how much is subjective - Please note that such stronger wheels may cause performance issues when running at PURE 360hz - if you have a high end wheel and experience very poor FPS, try setting FFB to "Pure 180hz". It should resolve the issues and any FFB fidelity loss should be negligible. EDIT: As per release notes from v0.9.8: The main change is the pneumatic trail fix via PneumaticTrailGripFractPower (PTGFP) function, which is embedded in the physics. It´s changed how pneumatic trail works and its effect on the FFB, which should provide a much more natural feeling for tire grip. We have also added a "FFB Low Force Boost" Slider to the Controller menu - this works sort of like a "Minimum Force" setting, in which higher settings (around the default 80%, recommended for Logitech wheels or similar) the forces come in earlier, while lower settings (20-40% which are the old defaults) are recommended for stronger FFB wheels such as T500, Fanatec CSR V2. If you have a Bodnar or an Accuforce-type wheel, you probably don´t need this setting at all and may keep it at 0%. The graph below gives an idea of how slider works: Adding this force boost slider allows us to set default values in Reafeel with more accurate values (less clipping) than before, since weak FFB on lower range wheels is less of an issue. PTGFP in turn makes FrontGripEffect in Realfeel unnecessary so that´s now set to 0.0 globally (vs 0.2 before). Finally FFB while the car is standing or moving very slowly has received some new code of its own (unrelated to the FFB while driving, though its effects can also be increased/decreased by the FFB Boost). We have added some lowe speed functions and tweaked the "parking lot" realfeel values to eliminate or at least minimise wheel vibrations / oscillations while standing still. All of these should hopefully grant Automobilista an all around stronger, more realistic FFB.
