    At first: stop screaming, nobody will take that post as serious.

    Update rate is 600Hz with command line option for 500 afaik.

    But: why do you think DD wheels need 180Hz? I've read a lot of stuff on that topic and have never read something similar. Yet the DD community is widespread across different boards and I'm far from knowing all of them, so I might have missed that

    Using the command line, you can set whatever Frequency you want up to 600Hz.

    It's easy enough. -ffb 600

    With that said, I'm not even sure it better things. For sure, some testing is needed.

    you set that command line in steam launch options, right? What am I supposed to use with a t300?

    I dug the info from an old post. There's no mention of the T300. Only the T500:

    In any case, just try to command. It won't hurt.

    Some of general impressions and questions related to FFB in PC2.

    First of all, I like it quite a lot. On a cheaper wheel like G27 with default presets (I use Immersive) you get less detail compared to, say, RF2 FFB, but the wheel feels closer to real life where details are not as pronounced, but you can still feel them. I drive an 2008 Impreza WRX where steering is quite damped, so it might not be a perfect reference for the in game Evo IX and VI I used to configure FFB.

    Being a guitar player, I must mention that the Gain - Volume - Tone setup model is, while being cool, a bit counter - intuitive.
    On a guitar amp you roll Gain down in order to get wider dynamic range and in order not to compress the signal by over-amplifying quieter sounds. Contrary to that, in PC2 you are suggested to have Gain at 100%, which I would expect to exaggerate lower strength signals and compress higher strength ones.
    As for the Volume control, I'm having hard time understanding what exactly it amplifies. It does increase heaviness, that's for sure, but is it the "natural" heaviness from forces coming from tires and suspension controlled by the Tone settings? In such case what are the exact effects that are controlled by the Gain setting?

    Re-watched the video where it was mentioned that Volume is what controls effects strength *before* Gain.
    Now I'm really confused

    In guitar world you use Gain to control preamp volume to boost lower signals. And then Volume to control poweramp and increase overall volume going to speakers.
    In PC2 the situation appears to be quite the opposite. Or did I get it wrong?

    In my view this is important, as not everyone have top wheels. Poirqc posted a very old link to a test of torque and response of some wheels, made by a developer if IRacing (David T)

    So here i post the results, so you could use the -FBB parameter with the correct value of your wheel.


    Logitech G25 (900 deg)

    500 hz update rate (2ms delay)

    9-10 ms latency (first move)

    Logitech G27 (900 deg)

    8 ms update rate

    Logitec Force 3D joystick

    34 ms latency (67 & 74 with wind up at end of travel)

    8 ms update rate

    Microsoft Sidewinder Wheel USB (red) (240 deg)

    60 hz update rate (14-16ms delay)

    44 ms latency (first move)

    ***Driver takes 8-16ms just to return from a call to getPosition and setForce

    Logitech Driving Force GT (DFGT) (900 deg)

    500 hz update rate (2ms delay)

    17 ms latency (first move)

    VPP

    56 ms latency

    8ms update rate (driver takes 24 ms after update!)

    calls to getPosition take 8-16 ms to return and up to 56 ms when applying a force!

    Frex

    44 ms latency

    16 ms update rate

    Big thanks to Mark Carpenter for the info!

    Sorry to bump this, but I found this update rate thing particularly interesting. Hopefully some developer or FFB specialist could help me.

    1) I have a Simucube OSW and ( in contrast to what Burningstar1983 is saying above) and I thought a high as possible update rate should be used, correct? As that would give the highest possible FFB update rate.

    I have my OSW registered in game as a "Custom" wheel.

    2) What is the default update frequency for the Custom profile?
    3) What is the highest possible update rate of the game?
    4) Is the FFB in any way related or limited to the FPS in the game? Its a real question, as people in Assetto Corsa complain about worse FFB when FPS drops.

    5) With the OSW that I use, on every profile (raw, immersive, jack spades, etc) I experience a vibration of about 20 Hz in the wheel in very specific situations. Namely: when steering in high downforce/high tire compression situations.
    Examples are:
    GT3 cars in the bottom of eau rouge steering uphill again and LMP1 cars in long fast corners. What causes this? Since it only occurs when the tires are highly stressed, I hypothesize it is the tire model that models: losing grip-->catching grip again--> losing grip again--> catching grip again. And that at a rate of about 20 Hz.
    Is this correct or am I feeling something different?

    Thanks!

    2) donīt know
    3) 600hz
    4) donīt know, but as my minimum and max FPS are always 60, I really canīt answer that.
    5) with my wheel i can feel pretty good the lost of grip but only when using the jack spade files with the following settings: 100:50-80:0:20, when i loose traction, the wheel just loose all the FFB.

    50-80= just to have a stronger FFB in some cars.
