Best rFactor 2 Wheel Settings for Logitech G29 / G920

rFactor 2 has perhaps the best force feedback system in any simulator I have played. I had heard good things about it, but I was still shocked at how good it really was on a lower-end wheel. You can feel everything about the track and grip level of the car in a very natural, realistic way.

The Logitech G29 and G920 work amazing well, but there are a few options that need to be set to get the game to work with the wheel properly. These are mostly related to having the game automatically use the real world steering angle for the car you are driving.

An odd omission from rFactor 2 is the lack of an on-screen FFB meter to see if the forces are clipping or not. I found a way to solve this using the free SimHub application. In this guide, I will show you how to get everything set up to fix these issues.

G HUB Settings

rFactor 2 automatically sets the proper steering angle for each car, so it is best to leave the rotation set to the maximum in G HUB and calibrate the wheel in-game.

Create a new profile for rFactor 2 with the following settings:

Setting Value
Operating Range 900°
Sensitivity 50
Centering Spring Off

rFactor 2 Settings

In Options > Calibrate > Steering:

Manually setting these options will force the game to properly match the real world steering angle to the rotation of your wheel, including a soft lock, so you can't turn past the maximum rotation angle.

Setting Value
Rotation limit mode Software
Max wheel angle mode Custom
Default max wheel angle 900 deg
Range set by vehicle Checked
Speed sensitivity 0%
Exaggerate yaw 0.0%
Look ahead 0.0%

Rotation limit mode tells the game to either change the wheel's maximum rotation at the driver level (G HUB) or to use an in-game solution. On these wheels, the Device Driver option doesn't work, so this must be set to Software.

Max wheel angle mode must be set to Custom. The game isn't able to properly detect the wheel's maximum rotation value.

Default max wheel angle must be set to 900, the maximum rotation angle of these wheels.

Range set by vehicle tells the game to automatically set the wheel rotation based on the real world car data. This includes a Soft Lock, so you won't be able to turn past the maximum rotation angle for the car you are driving.

Speed sensitivity will change the wheel's sensitivity based on the speed of the car. I never use things like this. They are really only useful when playing on a gamepad.

Exaggerate yaw is actually an in-game camera setting. It makes the camera rotate based on the direction of the car's movement. This gets set to -80% by default, probably because of a bug, which I find very distracting. I recommend trying this out, it's completely personal preference if you like it or not.

Look ahead turns the camera to look into the corners, which might make it easier to see the apex of the corner, depending on your monitor setup.


In Options > Calibrate > Force Feedback:

Setting Value
Type Wheel
Smoothing 4
Car specific multiplier 100%
Minimum steering torque 11.0%
Steering effects strength Positive

Smoothing is largely dependent on the track and how you have your wheel mounted. The smaller the value, the more detail you will feel. With these wheels, setting this too low makes the wheel vibrate too much, especially over kerbs, becoming a noisy distraction. I find 4 to be about as low as I can go before I find the vibrations distracting.

Car specific multiplier controls the overall strength of the wheel on a per-car basis. I haven't had a problem keeping this at 100%, but feel free to adjust this higher or lower depending on the car and track combo. You can use the FFB Meter described below to determine if the force feedback is clipping or not. This setting is saved for each car individually even though it appears to be a global setting.

Minimum steering torque tells the game to amplify the very weak forces to a point where it can actually be felt in the wheel. These weaker wheels don't have enough fidelity to reproduce very small forces, so we raise this. You can find the exact value for your wheel by using the WheelCheck program and running the Min Force test.

Steering effects strength needs to be set to Positive for these wheels. Most other simulators call this the "Invert Force Feedback" setting.

FFB Meter On-Screen Display

For some reason, rFactor 2 lacks a way to see if the force feedback is clipping. This can be solved by using a free, third-party application called SimHub. This will create an overlay that can display any information you want, including an FFB meter.

I learned how to do this from a very helpful video by brobot on YouTube: How to create FFB meter for rFactor 2 using SimHub.

That video shows how to create an overlay with meters for the pedal inputs as well as the FFB. Here are the instructions for creating the FFB Meter alone:

  1. Download and install SimHub from the official website.
  2. Open SimHub and select Dash Studio from the sidebar.
  3. Click the "New Dashboard" button and name it "FFB Meter".
  4. From the right panel, click on "Dashboard."
  5. Under Dashboard Properties, set the Width to 40 and Height to 140.
  6. From the left toolbar, from "More Components", select "Vertical Linear Gauge".
  7. From the right panel, click on "Screen" and select "VerticalLinearGaugeItem0" from the components list.
  8. Set the values as follows:

    Setting Value
    Top 0
    Left 0
    Width 40
    Height 140
    Background Color Transparent
    Gauge Color Red

    For the Value, click on the "fx" button, choose "Computed Value" and paste into the NCalc Formula:

     abs([DataCorePlugin.GameRawData.forceFeedback.mForceValue])*100
    
  9. Close the Dash Studio window.
  10. In the main SimHub window, find the FFB Meter at the bottom of the list. Click on its preview image to start it in Windowed mode. A small black window will appear on your screen that can drag anywhere you like, even while the game is running.
  11. From the Games section, select rFactor 2. The first time you do this, it will install the necessary files into the rFactor 2 folder automatically.
  12. Launch rFactor 2. From the rFactor 2 Launcher > Options > Video Settings, set the game to run in Windowed or Borderless mode for the meter to appear.

Now you can easily tell if the force feedback is clipping or not as you drive. Momentary spikes are fine, but you don't want any sustained periods where the meter is full, usually while cornering or under heavy braking. By watching this meter while you drive, you can raise or lower the car specific multiplier setting to the point where you have no sustained clipping.

Conclusion

rFactor 2 is remarkable for how well its force feedback works, especially on these lower-end wheels. It really is the benchmark to which all others should be compared. These tweaks make it just that much better.
