Understanding and Fixing Oscillation in Sim Racing
Sim racing is all about precision, immersion, and control. However, one common issue that plagues many sim racers is oscillation—the uncontrollable back-and-forth movement of the steering wheel when the car is moving in a straight line. If you’ve ever let go of your wheel and watched it shake violently on its own, you’ve experienced oscillation firsthand.
In this blog, we’ll cover what oscillation is, why it happens, and how you can fix it to improve your sim racing experience.
What is Oscillation in Sim Racing?
Oscillation in sim racing refers to a repetitive, rapid movement of the steering wheel, usually occurring when the car is moving in a straight line or at high speeds. This issue is most common in direct drive wheelbases but can also be found in belt-driven and gear-driven wheels if force feedback settings are not properly tuned.
What Causes Oscillation?
Oscillation is primarily caused by force feedback settings that are too aggressive or unbalanced. Some of the most common culprits include:
-
Excessive Force Feedback Gain – When force feedback is set too high, the wheel becomes overly sensitive and exaggerates movements, leading to oscillation.
-
Damping and Friction Settings Too Low – These settings help stabilize the wheel and reduce oscillations, but when they are too low, the wheel reacts too freely, allowing oscillations to occur.
-
In-game Force Feedback Effects – Some racing sims have built-in force feedback effects that can contribute to unwanted oscillations if not properly adjusted.
-
Improper Steering Rotation or Soft Lock Settings – A mismatch between the in-game steering rotation and the hardware settings can result in unwanted wheel behavior, including oscillation.
-
Vehicle-Specific Factors – Certain cars in sim racing titles may be more prone to oscillation due to how their physics engines interpret force feedback.
How to Fix Oscillation in Sim Racing
Luckily, there are several ways to reduce or eliminate oscillation in your sim racing setup. Here are some key adjustments you can make:
1. Adjust Force Feedback Strength (Gain) & Filters
-
Lower the FFB gain in-game to prevent excessive force output.
-
Increase the damping and friction settings in your wheelbase software to add resistance and stability.
-
Some wheels also have a natural inertia setting—raising this can help smooth out force feedback response.
2. Enable Minimum Damping and Friction
-
Most wheelbases (e.g., Simucube, Simagic, Fanatec) have dedicated damping and friction sliders. Adjust these until the oscillations stop.
-
If your sim supports it, increase minimum force slightly to balance subtle force feedback details.
3. Match Steering Rotation in-Game & Wheel Software
-
Set your maximum steering rotation in both the game settings and your wheel software to avoid mismatched force feedback responses.
-
Use the soft lock feature if available, so your steering wheel stops at the correct limit based on the car you’re driving.
4. Adjust Deadzone & Linearization
-
Some games allow you to tweak the force feedback deadzone or linearization settings. These adjustments can help mitigate oscillation by smoothing out force transitions.
5. Update Firmware & Drivers
-
Ensure your wheelbase is running the latest firmware and software updates. Manufacturers often release patches to fix force feedback issues and improve overall stability.
6. Car-Specific Adjustments
-
Some sim racing titles allow for car-specific force feedback tuning. If a particular car has excessive oscillation, tweaking the settings for that car might be the best solution.
Conclusion: Eliminating Oscillation for a Smoother Sim Racing Experience
Oscillation in sim racing can be frustrating, but with proper tuning, it can be minimized or eliminated. By adjusting force feedback strength, increasing damping and friction, matching steering rotation, and ensuring your firmware is up to date, you can take full control of your sim racing setup and enjoy a more realistic, immersive experience.
