    Thx for the new info and guides.
    First post updated.

    A noob question :eek:
    What are the Spring, Damper, Friction and Inertia effects?

    Spring is a force opposing the wheel rotation. Spring torque is proportional to wheel position (zero at center, max at max rotation angle)
    Damper is like a viscous force that "smooth" the rotation of the wheel, so much probably is proportional so rotational speed (faster you try to rotate much damping you feel).
    Friction should be a constant force opposing the rotation.
    Inertia is a force opposing the start of rotation, so it is max when you start rotating and then decrease to zero.

    This is just awesome. Keep it coming please.
    Can you explain Saturation in effects.

    The first and second post may need to be updated as I'm pretty sure (Andrew_WOT agrees) filter is not a master slider which adjusts damper, spring, friction, and inertia all at once (or in any way) but rather a different setting entirely which acts like the smoothing setting in RF2.


    Inertia and dampening feel the same to me on the desktop. I thought inertia was going to be a totally different thing. Maybe I just need to test it in-game. Same with friction - it also feels like dampening on the desktop (other than the vibrating when you raise it).

    Le566 gave pretty good explanation of this one
    I think that as a final result it smoothes out "Effects" as well.

    As for saturation, as Jason explained it to me on the example of dampening, the lower the saturation the less pronounced the effect is on small wheel corrections, so you still feel wheel weight overall but minute adjustments are still nimble.

    I don't understand you well Andrew (sorry for my english).
    Does it affect reducing the effects? (what i understand in your post).
    Or capping the effects above the saturation percentage? (what i understood in previous posts).

    I found this image on the german forum:
    https://drive.google.com/file/d/0B_v4NspCnMOPX1doZzNGM2dFSEU/view?usp=sharing
    Image is self explanatory and it is valid (I suppose) for the other effects also.
    I.e. for the Spring effect the x-axis label should be "Wheel position 0-100%" and the y-axis label "Spring Force %"

    Indeed, thanks for that. Not even close to what I was told on iRacing.
    So essentially the force ramps up to saturation point and after that just stays linear flat w/o additional increase in resistance, becomes fully "saturated".

    Aded the Device Setup section to the first post.
    I've fullfilled some parameters, asking for help and looking for info.
    Any help is welcome.
    Thanks

    ¿1 week? to receive my OSW. :rolleyes:

    OK, so can we confirm if filter is basically a smoothing option (like smoothing in RF2) which smoothens all FFB output or not?

    On another note, it's weird how friction and especially inertia feel almost exactly like damping, well, at-least on the "desktop" settings they do.

    I've tried tons of different setups of the three sliders in rF2 and I feel ABSOLUTELY nothing, no differences at all.
    So, for sure the effect of the filters is not what I described earlier in this thread and I was wrong on that, but also they doesn't seems to have any effect on the FFB feeling.
    Maybe because rF2 doesn't use those canned effects?
    No effect at all even in Assetto Corsa.

    Don't know, maybe Friction and damping are somewhat similar, but Inertia have a completely different feeling, at least to me.

    I don't think so. In the T500 i felt the difference changing Spring and Damper. And These where canned effects too. Could be possible something related to the MMOS?

    I usually leave Effect Filters alone and just use Overall Filter.
    I can certainly feel them doing their thing when playing with Desktop effects. As far as titles go, Friction Effect filter seems to be working with Dirt Rally, guess because they use a lot of this effect there. BTW, keep in mind that Dirt Rally also leaves some residual effects after exiting the game, so it's always better just to restart controller to clean it out.

    In RF2 I think that those 3 sliders doesn't have effect, but User effect does, Damping for example. And the game needs to be restarted for it to take effect.

    I personally don't use any of effects, just Overall filter at 8 and max force at 100%. Then STS at 0.200 in controller config file. And in-game FFB Multi depends on the car, usually around 0.60-0.80
