Current Known issues and common fixes:

New in Version 1.2

  • You should launch the game from Steam or using start_protected_game.exe – failure to do so will mean online is not available. Some launchers from manufacturers or 3rd party developers may need to be updated to work.
  • Easy Anti-Cheat fails to launch or is not installed – reinstall EAC
  • Skipping a full formation lap breaks the race start (expected fix Patch 1 [w/c 15th Dec])
  • Occasionally, at the end of a race, pressing Esc does not return you to the results screen (expected fix Patch 1 [w/c 15th Dec])
  • Sometimes the AI is swapping to wet tyres inappropriately (expected fix Patch 1 [w/c 15th Dec])
  • OpenXR Toolkit does not function with EAC. We are awaiting Epic support (date TBC)
    • You may find that Virtual Desktop replicates some features you are using
    • If Epic is unable to support, we will implement important features directly (likely earliest date would be in January)
    • Custom runtimes are not available – you will need to remove them from the install folder
  • 0xc000007b – means a local file is incompatible with the game, usually reinstalling should be the fix (please delete any leftover files)
  • PluginsAdapter.exe is being flagged by some anti-viruses. Please allowlist this or delete this file and run the game without Plugins.
  • Wheels/pedals that are plugged into USB hubs may be significantly impacting performance – please test directly plugging into the PC
  • Logitech DFGT, G27, G29, and G923 can be impacting game performance – we are investigating, but you may be able to uninstall the Logitech software and reinstall it.
  • NVIDIA GeForce Now is not functioning – we have messaged them for guidance
  • Reshade is no longer supported

Very Important & General

  • Le Mans Ultimate is only supported on Windows machines that meet the minimum requirements. Mac, Linux, and Steam Deck are unsupported
  • Some plugins are causing crashes – to disable:
    • Navigate to Steam\steamapps\common\Le Mans Ultimate\UserData\player\CustomPluginVariables.JSON,
    • Open the file and set “Enabled” to 0 on all entries,
    • Save and re-open the game
  • “Failed to allocate a section of memory” – Windows page file being too small can cause a memory usage issue, particularly for users with less RAM. Please see Common Fixes. In general, you should have at least 32GB of virtual memory and close
  • Users who have their Windows region settings to have “decimal” as “,” and “digit group symbol” as “.” should invert this – the game may not be able to launch without being in this format.
  • Unfortunately, there is a known issue with Intel GPU cards. Here is a link to the GitHub thread where the Intel community team is feeding back to their community on the fix their side – https://github.com/IGCIT/Intel-GPU-Community-Issue-Tracker-IGCIT/issues/1038. There isn’t anything we can do to speed this up, unfortunately.

AI

  • The AI will occasionally come too close to you when lapping in some situations

Broadcast Overlay

  • FCY is displaying as “Code 80.”
    • NRG bar is displayed backwards on the Driver Overlay
    • Sometimes tyres are incorrectly displayed
    • Social media prompt occasionally is triggered and is unstyled

Co-op

  • The average lap time statistic is not always working
  • Score updates are not always displayed after receiving a handover
  • During a pitstop, the stint review menu can display your drive time as 0h 0m
  • Motor map and regen settings can be changed after loading into a session
  • Advice – the team creator can still reassign drivers through the drop-down menu after using the swap driver button
  • Advice – Handing a session back to the host after they have closed the session restores it

Hosted Servers

  • Hosted Servers currently do not offer a Full Rolling Lap start
  • When joining the Hosted Servers, the event screen may show an incorrect map for circuits with alternate layouts, but it will still load the correct track

Input Devices

  • Certain Thrustmaster devices can disconnect after multiple sessions (TMX, T818, T248, T150, T300RS) – advice is to completely re-install Thrustmaster software and firmware
  • Controllers are not able to navigate through menus, including the pause screen
  • Controller users are likely to experience higher tyre degradation due to generally more aggressive 
  • To adjust controller vibration, you need to adjust “Force Feedback.”
  • Fanatec GT DD Pro – Assigning “Brake migration Forward” and “Brake Bias Forward” to any button on the wheel will cause the setting to be repeatedly pressed
  • Logitech users who have their wheel stuck to one side should enable “constant steering force” in the settings

Online

  • Online is greyed out. This could be either:
    • You need to make an online account and/or accept the terms and competition rules – click on profile, then the pencil to change this
    • Your Steam authentication has expired – try restarting the Steam application (make sure you exit Steam in the system tray, not just close the window)
  • Unable to join servers
    • Ensure your time zone in Windows is set to “automatic.”
    • Verify the integrity of files in Steam – you may need to delete the “Installed” folder first
    • Users based in Russia are unable to connect to most servers due to restrictions either by Russia or some server providers
  • Profile
    • Users cannot change their name more than once in a 3 month period, but no warning is shown
    • If there is more than one user with the same name, the subsequent users are given a # with four random digits (e.g. Joe Bloggs#1234) – you can change your name to be unique (for example, include an initial)- this will remove the numbers
      • Please note: players can only update their name once every 3 months
  • On-track
    • If you join an online session once the timer has expired, you do not have control of the car and can not take control (nor should you, but it isn’t explained)
    • In practice and qualifying sessions, if a user joins after you, they will be displayed in a temporary car. This is currently a Porsche 911 GTE regardless of category. Returning to the pit lane, then going into the setup menu, should resolve this. Alternatively, a user may map a button to “load vehicles” to reload the skins. Important note: please do not do this whilst driving, as it may cause a screen freeze

On-track

  • General
    • Ultra settings are performance-heavy and may result in less-than-desirable frame rates
    • Low grip on track – check your “Real Road” is set to have some rubber (advanced session settings). There are no tyre warmers in WEC (except Le Mans) by default, but you can now apply a tyre warmer to help. It’s also worth checking the road temperatures, as these are separate from ambient temperatures
    • Losing Force Feedback (FFB) – map a “Reset FFB” button in Settings > Controls and use when appropriate
    • Cars stuttering

Save and Load

  • Motor map and regen settings can be changed after loading a save file

UI

  • Upon leaving a server, the UI can occasionally freeze in a “dead state” but not crash – you will need to manually close the application and re-open it
  • The UI will sometimes not disappear when pressing the drive. Simply hit escape twice in this situation.
  • Localisations
    • Translations may result in odd text placements or clipping in the UI
    • Some phrases, when translated, may need further review
    • Some words or phrases may be missing translations

Vehicles

  • General
    • BoP is not final and will be iterated on in the future with further per track.
      • ABS has been completely changed, which will affect handling in this category
    • The highest in-car traction control settings can significantly affect top speed

VR

  • Motion Blur is disabled completely in VR
  • When loading replays from the main menu in VR, the replay will only show on the VR mirror.
