Troubleshooting Force Feedback (FFB)

Known Issue: FFB in Version 1.3

We are aware of an FFB filtering issue introduced in the 1.3 update causing excessive oscillation on certain cars. Our team is actively investigating.

A test build is available via Steam's pub-share beta with alternative input filtering that may help:

• Right-click Le Mans Ultimate in Steam > Properties
• Go to Game Versions and Betas
• Enter access code: rNZ553qE8gWd
• Click Check Code and opt in to the pub-share branch

Note: The Duqueine is the main known problem car on this build. Only opt in if experiencing FFB oscillation issues.

FFB Has Completely Stopped Working

1. Reset FFB button: Map a button to "Reset FFB" in Settings > Controls, press during session.
2. Restart fully: Exit to desktop (not just main menu) and relaunch.
3. Reinstall wheel software/firmware: Uninstall completely, reboot, reinstall latest version.
4. Check in-game settings: Settings > Controls > Force Feedback. Confirm multiplier is not zero.
5. Verify game files: Steam > Right-click LMU > Properties > Local Files > Verify integrity.

Temporary FFB Loss When Other Players Join

Known issue: brief FFB loss when another player joins your practice server. Temporary - restores automatically.

FFB Spikes or Random Jolts

• Reduce FFB Smoothing or Minimum Torque in Settings > Controls > Force Feedback.
• High-torque DD units: reduce in-game FFB to 50-70%, increase force via wheel software.
• Ensure wheel firmware is up to date.

Wheel-Specific Issues

• Thrustmaster: Full software and firmware reinstall typically resolves FFB loss.
• Fanatec GT DD Pro: Clear "Brake Migration Forward" / "Brake Bias Forward" bindings if FFB is erratic.
• Logitech: If wheel pulls to one side, enable "Constant Steering Force" in settings.
