Understanding Force Feedback Linearity (FFB LIN) in Fanatec’s Tuning Menu

Force Feedback Linearity (FFB LIN) is a setting in Fanatec’s tuning menu that adjusts how linearly the wheel base translates force feedback signals from the sim racing software into actual motor output. In simple terms, it controls whether the force feedback strength scales in a smooth, linear progression from light to heavy forces—or if it applies a more aggressive force curve where stronger feedback is prioritized.

With FFB LIN ON, the wheel base applies a fully linear force feedback curve, meaning small in-game forces produce small physical responses, and large in-game forces produce large responses in equal proportion. This ensures that what you feel in the wheel exactly matches the physics engine’s force output.

With FFB LIN OFF, the feedback is non-linear. The wheel exaggerates weaker forces slightly and compresses stronger ones. This can give the sensation of more road detail or sharpness at low torque levels, which may feel more engaging—especially on lower-torque wheel bases or in games where subtle forces are otherwise hard to feel.

Turning FFB LIN ON is generally recommended for professional or competitive sim racers who want the most accurate and predictable response—particularly useful in simulators like:

• iRacing – Known for precise physics and force feedback fidelity, where a linear response helps maintain consistency.
• rFactor 2 – Offers highly detailed and nuanced force feedback, making linearity essential for tire slip cues.
• Automobilista 2 – Delivers raw FFB output that benefits from linear scaling to avoid clipping or misleading weight transfer feedback.

However, FFB LIN OFF can be beneficial in:

• Assetto Corsa – Some users prefer a non-linear feel to enhance road texture and curb feedback, especially with lower torque settings.
• F1 25 – A slightly non-linear curve can help emphasize lighter forces for better control during quick direction changes.
• Forza Motorsport – Casual or semi-sim titles may feel “stronger” and more engaging with FFB LIN off.

FFB LIN isn’t a setting you “max out”—it’s binary: ON or OFF. There’s no right or wrong, but there is a best choice depending on your preferences, hardware, and sim title. For high-end wheel bases like the Podium DD1/DD2, keeping FFB LIN ON maximizes their capability to deliver ultra-accurate feedback. On mid-range systems like the CSL DD or ClubSport Wheel Base, OFF might enhance detail without overwhelming the motor.

• ON: If you want realism, play physics-heavy sims, and have a powerful direct drive wheel.
• OFF: If you prefer more exaggerated or tactile feedback, play more casual titles, or want a punchier feel at lower torque.

Ultimately, test both settings in your favorite sim and adjust based on how natural and responsive the wheel feels to you.
