Occasionally some anti-virus protection needs to allow the game executable or folder to be excluded to run. For our guide on this for Windows Defender, please click here
Users may experience poor performance in UI menus please see Common Fixes
Users that have not yet validated their email address will get a prompt to do so and may be excluded from online racing unless this is completed
MSI Afterburner and RivaTuner Statistics (and possibly similar programs) have been reported to cause performance issues. We would recommend you disable these for now whilst investigations take place.
Running an instant replay tool such as Nvidia Geforce or the Xbox tool is causing issues
A VR headset, plugged in but not in use can cause severe graphical issues throughout the game UI and on track. This may also be caused by other devices but not known at this time.
Rarely, users may experience very frequent stutters in gameplay. If you experience this try this fix - visit the root folder C:\Program Files (x86)\Steam\steamapps\common\LeMansUltimate\UserData\player\settings.json and set "Record To Memory":true, (change from false to true). Users can also try disabling one or more opponent classes to reduce CPU overhead.
“Failed to allocated a section of memory” - Windows page file being too small can cause memory usage issue particularly for users with less RAM. Please see Common Fixes
Note: Le Mans Ultimate is only supported on Windows machines that meet the minimum requirements. Mac, Linux and Steamdeck are unsupported
Gsync is not working in borderless mode

General
Users may experience poor performance in UI menus please see Common Fixes
Page transitions may experience a slow-down during animations for some users
Tracks show a new asset icon marker, when there are no new tracks.
Some imperial measurements are not equivalent to metric across the game
Some text clips on lower resolution settings
Custom graphics presets are not saving
500 error - we are investigating this but seems to be related to slow loading for users with lower spec hardware and HDDs. This may be improved on second load or by running races with no (or fewer) AI as well as smaller circuits.
Race Weekend Configuration
Sebring race length is set to minutes, not laps
A user setting “RealRoad Wet” (to start with a wet track) in advanced options will find that this is not currently being applied

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 to change this
Your steam authentication has expired - try restarting the steam application (make sure you exit steam in the system try, not just close the window)
When loading into a session the UI is incorrectly displayed until all cars are loaded and a user is placed in the garage
Chat remains persistent between sessions and is not cleared
Race Monitor
Switching between tabs can cause a visual stutter
Setup
Degree symbol (°) displays as “??”
Save setup displays a list of tracks with incorrect naming conventions
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
On-track and AI
On-track
Ultra settings are performance heavy and may result in less than desirable frame-rate
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). It’s also worth checking the road temperatures as these are separate to ambient.
Being in watch mode while server transition between sessions gets the player stuck in watch mode
AI
AI may fail to wait for a gap coming out of the pits and crash into each other in practice and qualifying sessions
Time scaled races with AI may result in them pitting too often
Vehicles
General
Both front and rear lights flash when user uses “headlight pulse”
BoP is not final and will be iterated on in future with further, per track, applications
The highest in-car traction control settings significantly affect top-speed
GTE
Corvette C8.R GTE
Centre mirror is non-adjustable
Input Devices
Controllers are not able to navigate through menus, including the pause screen
Controller users are likely to experience higher tyre degradation
To adjust controller vibration, you need to adjust “Force Feedback”
Some manufacturer SDKs may need to be updated by the development team to be compatible with displays or LEDs
Some controllers are not being picked up by the game, please report these. Users can, in the meantime, assign controls themselves
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

UI
When loading into a session the UI is incorrectly displayed until all cars are loaded and a user is placed in the garage
Profile
A user’s flag does not update immediately if they are already registered for the next race
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)
Race Results
Disqualified users display as DNF in race results
Contacts
Some contacts with self are reported when it should state another player’s name
On-track
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 pitlane, 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
If a user sets their best qualifying lap time after the chequered flag this is not being written to the results file so the post-race feedback shows an incorrect despite actually starting in the correct position

Race Weekend Configuration
Default race weekend settings are not loaded when you start the game for the first time or restart the game (a user can click on a different race and it will load correctly). This can result in incorrect grip levels and unexpected session lengths.
Minimum race length is 5% of its real-life equivalent, for example, Spa Francorchamps minimum race length is 18 minutes
Sebring race length is set to minutes, not laps
A user setting “RealRoad Wet” (to start with a wet track) in advanced options will find that this is not currently being applied
The minimum length of a race session in quick configuration remains the same value as the user’s last race (this can be remedied by going to advanced options or clicking to increase the value before returning to the length you desire)
