    Hi guys, hope I’m posting in the right thread! Regarding the post about the new FFB: it mentioned that if my wheel profile is missing, I should let you know. So, here I am — the PXN VD4 needs a profile! Or does it?
    I’ve tried the new FFB after a long break and I'm impressed; I can feel the forces acting on the tires much better than anywhere else, which is great. However, it feels like something is still missing. Do you have any tips on how to tune the wheel base settings itself?
    One more thing: I'm experiencing oscillations (the wheel wandering) when letting go of the rim on straights. Is this a common thing for 4-6 Nm wheel bases? Any advice on how to fix this?
    Best regards.

    Post the .rcs file of your control profile that you created in the game. You can find this file here: Documents\My games\SimBin\RaceRoom Racing Experience\UserData\ControlSet
    This will allow the devs to add a default profile for this wheel.

    The go-to advice for DD wheels in Raceroom is to tune down or turn off all post-processing effects like dampening, inertia, friction, centering force, etc. However, since you have oscillations while driving straight, these setting are likely already low or off. You can add a bit of dampening or friction to reduce this, or if this effect is only present when you let go of the wheel and doesn't occur when you're simply keeping your hands on the wheel, I wouldn't worry about it. You normally shouldn't let go of the wheel while driving, right? Unless you lost conrol and are about to crash into a hard object.

    Also, turn down FFB filter/interpolation/smoothing (however it's called in the wheel's software) as much as possible unless you experience some unwanted side-effects like vibrations or "notchiness".

    What you feel missing is probably road effect, many people complain about that, but that's just what the game is. To address that, you can increase Bump amplification in the game setting, FFB tab. Also, try adding 1-2% of Minimum force.

    Another thing to look out for in your case is max steering angle of your wheel in combination with Steering lock value of your car (on the car setup page). Since your wheelbase doesn't have a default profile, it probably doesn't adjust max steering angle automatically to sync it with the steering angle of the car, but also the default Steering lock for all cars is probably 18 degrees. While you can find your car's default steering angle on the car setup page, the default Steering lock will always be 18 and there's no way to find the correct, native value without adding your wheel to steering_wheels.xml (you can find it in Steam\steamapps\common\raceroom racing experience\Game\GameData\General).

    So the most simple thing to do would probably be to just experiment with max. steering angle in your PXN software to find the value that feels the best for you and just keep it like that for all cars. With the default Steering lock of 18 degrees, a good steering angle value would probably be between 400 degrees (if you prefer fast steering) and 600 (close to default GT3s/TCRs steering ratios).

    Also, good to know that VD series wheels work fine in the game without issues (other than missing a profile and steering angles).

    Thank you very much for the info! I’ve adjusted my settings based on the recommendations, and it’s definitely an improvement. :)
    I agree, the wheel works great and is easy to tune. I managed to bring out the missing sensations by increasing the multiplier. My settings are attached below. )
    Best regards.

    @Peter Koch Could you pass this file forward to devs?

    Unpack and drop this in the main Steam folder, please report if it shows in the contolset menu as ''PXN VD4''

    Yes, it shows up. I also wanted to add that besides the steering lock not changing automatically, the "Stationary Friction" isn't working either — it doesn't change regardless of the value

    When? not moving the car?
    You have Damping on in the wheel driver?

    Yes, when the car is on the spot. Filter and damping are disabled in the driver.

    Try enabling damping in the drivers. It is possible that this is not a post-processing effect, but the strength of FFB effect "Damping", the game uses it to simulate stationary friction.

    I did a lot of testing, tried different settings. I don't know how or why—the friction effect started working, but not for long ( and I couldn't replicate the situation to make it work again. This makes me wonder: what other effects might not be working properly without me even knowing about it? Maybe that's why I don't feel wheel locking or excessive understeer?

    The only two other effects that the game uses are: 1) sine wave, to create all the FFB while driving; 2) spring effect, as a soft-lock when Spring-based steering lock is enabled (it's a hidden feature though and is only enabled on a handful of wheels by default).
