SimSightline / LMU Settings
Best LMU Settings
Le Mans Ultimate needs two things set right: force feedback for your wheel, and graphics that hold a steady frame rate in a 60-car field at night. Start here, with every value linked to the wheel maker, a coaching site or Studio 397's own guide.
LMU force feedback settings explained
Settings → Controls → Force Feedback (in two blocks, Feedback Settings and Advanced). Steering range is on the Calibrate tab, and kerb rumble and tyre slip vibration are under Settings → Controls → Haptics.
- Use Steering Wheel Range from Vehicle: on. LMU then sets each car's real steering lock, as Studio 397 recommends.
- Force Feedback Strength: overall force. On strong direct drive bases, 50 to 70% avoids spikes; weaker wheels run higher.
- Force Feedback Smoothing: keep it low (0 to 5). It adds damping and a little delay.
- Minimum Steering Torque: 0% on direct drive; a little only on weak gear-driven wheels.
- Steering Torque Capability: your base's torque in Nm, where the setting is shown (for example 5 for a T598, 12 for a MOZA R12).
- Steering Torque Sensitivity: 100% to start; some guides go to 150% for more feel.
- Collision Strength: lower it if crashes and kerb strikes jolt the wheel.
- Invert Force Feedback: depends on the wheel. If the wheel pulls away from centre instead of towards it, switch it.
LMU FFB settings by wheel
| Wheel | Strength | Smoothing | Min torque | Torque capability | Sensitivity | Collision |
|---|---|---|---|---|---|---|
| Fanatec (CSL DD, GT DD Pro) | 85 to 90% | 0 to 5 | 0% | – | 100 to 150% | 50 to 100% |
| MOZA (R5 / R9 / R12) | 60 to 90% | 0 | 0% | 5 / 9 / 12 | 100 to 150% | 100% |
| Logitech RS50 / G PRO | 80% | 0 | 0% | – | 100% | 100% |
| Thrustmaster T598 | 125% | 0 | 0 | 5 | 100% | 100% |
| Thrustmaster T818 | 40% | 0 | 0 | 10 | 100% | 100% |
| Simagic (any EVO base) | To taste | 5+ if bumps are harsh | – | – | – | Lower if spiky |
| Simucube | 50 to 70% | Low | 0% | – | – | – |
| Asetek (any base) | 65 to 70% | 0 to 1 | 0% | – | 100% | 55 to 75% |
Ranges combine Coach Dave Academy (Fanatec, MOZA), Logitech, Thrustmaster, Simagic and Asetek guides and Studio 397's advice as compiled by SimRacingCockpit. Where sources differ, we show the range. Constant Steering Force Effect: off for direct drive (Logitech suggests turning it on only if the wheel pulls to one side with no detail).
Wheelbase software settings for LMU
- Fanatec (FanaLab / tuning menu): SEN 900 or Auto, FFB 100%, FFS Peak, natural damper, friction and inertia off, interpolation off or low, FEI 100. Turn off Dynamic Force Feedback (D-FFB) in FanaLab. CSL DD values for other sims: Fanatec CSL DD settings.
- MOZA (Pit House): steering angle 900°, game FFB intensity 100%, max output torque 100%, natural damping, friction and inertia 0, spring 0, linear curve. Studio 397 notes the default LMU preset can cause issues; try a Performance preset if so. R5 owners: see our MOZA R5 settings for every sim.
- Logitech (G HUB): compatibility mode RS or PRO, strength 8 Nm (RS50) or 11 Nm (G PRO), FFB filter 4, dampener off, TRUEFORCE audio 60, angle 900°.
- Thrustmaster T598 (on the base): master gain 100%, mode Extreme, inertia high, friction off, damper 0%, spring auto. T818: master gain 100%, damper 0%, mode Performance.
- Simagic (SimPro Manager): load the Le Mans Ultimate preset for your base, auto switch on, output 100%. Other sims: Simagic Alpha EVO settings.
- Simucube (Tuner): detects LMU automatically; set strength in Tuner.
- Asetek (RaceHub): import the LMU preset and save it to the wheelbase.
Map a button to Reset FFB in Settings → Controls in case the force feedback ever drops out.
LMU graphics and performance settings
From Studio 397's official Performance Optimization Guide:
| Setting | Recommendation | Why |
|---|---|---|
| Visible Vehicles | 10 to 15 (below 20; 10 or less in VR) | One of the biggest CPU savings, especially in big grids |
| Shadow quality | Lower if you need frames | Large GPU cost |
| Reflection quality | Medium | Good balance for most PCs |
| Ultra presets | Avoid when racing | Keep them for screenshots and video |
| Sound channels | 128, or 64/32 if you stutter | Reduces CPU load |
| Garage Car Detail (settings.json) | 0.01 | Only lowers detail of cars in the garage |
| Windows pagefile | Manual, 64 GB on an SSD | Reduces stutters in big sessions and VR |
- Presets by PC: entry level, everything low with 10 visible vehicles; mid-range (RTX 3060 / RX 6700 XT class), mostly medium with 15; high-end (RTX 4070 / RX 7800 XT class), mostly high, no Ultra.
- Find your limit: if the GPU sits near 99%, lower reflections, anti-aliasing, textures and draw distance. If the CPU is maxed and the GPU is not, lower visible vehicles, opponents and sound quality.
- Test on the hardest tracks: Le Mans, Fuji and Portimão, ideally at night in the rain with a full grid.
- First lap stutter on a new track is shader compilation and only happens once.

LMU VR settings
- Set supersampling in SteamVR or OpenXR, not in game: start at 100%.
- Turn on fixed foveated rendering if your headset supports it, and keep reprojection or ASW on as a safety net.
- Visible vehicles 10 or less, and motion blur off.
FOV and seat position
LMU's field of view is a vertical FOV slider in the graphics settings, and the correct value depends on your screen and distance. Use our LMU FOV calculator, then move the seat in the cockpit so the virtual wheel matches yours. Map seat adjustment to buttons so you can fine-tune it on track. Our seat position guide covers your real seat.
Racing other sims too? See our ACC settings, iRacing FFB settings and AMS2 FFB settings.
FAQ
What are the best LMU force feedback settings?
Use Steering Wheel Range from Vehicle on, Strength 85 to 90% on Fanatec and most mid-torque bases (50 to 70% on strong direct drive), Smoothing 0 to 5, Minimum Steering Torque 0%, Steering Torque Sensitivity 100%, and Steering Torque Capability set to your base's Nm where shown.
What are the best LMU graphics settings for FPS?
Visible vehicles 10 to 15, shadows lowered, reflections medium and no Ultra presets while racing. Lower sound channels to 64 or 32 if you stutter, and set a 64 GB pagefile on an SSD.
What are the best LMU settings for a Fanatec CSL DD?

What are the best LMU settings for a MOZA wheel?
Steering Torque Capability to your base's Nm (5, 9 or 12), Strength 60 to 90%, Smoothing 0, Minimum Torque 0%. In Pit House: 900°, game FFB intensity 100%, natural damping, friction and inertia 0, linear curve.
Why does my wheel pull the wrong way in LMU?
Switch Invert Force Feedback. Whether it should be on or off depends on the wheel and driver.
How do I set FOV in Le Mans Ultimate?
Use the vertical FOV slider in the graphics settings, with the value from our LMU FOV calculator for your screen size and distance.
