Le Mans Ultimate Competitions Paused as Version 1.4 Issues Persist

Le Mans Ultimate Competitions

Low Fuel Motorsport and Virtual Motorsport Series have postponed high-level competition while problems involving multiplayer contact and brake cooling remain under investigation.

Two Le Mans Ultimate competitions have been paused while technical issues introduced or exposed around Version 1.4 remain unresolved.

Low Fuel Motorsport announced on August 18 that its Simverse Pro Series has been suspended until further notice, while Virtual Motorsport Series has postponed the continuation of Season 5 of its Pro competition. Both organizers are waiting for the relevant problems to be addressed before racing resumes.

Low Fuel Motorsport suspends Simverse Pro Series

Low Fuel Motorsport has suspended the Simverse Pro Series, citing the current technical state of Le Mans Ultimate.

No new date has been announced for the championship to resume.

Virtual Motorsport Series has also postponed its Pro competition. The championship features seven splits and around 250 drivers, with paid entry and prize money across its top four divisions.

VMS is working with drivers and Studio 397 while the affected areas are investigated.

Multiplayer contact behavior is under scrutiny

One of the main problems reported since Le Mans Ultimate Version 1.4 launched on July 28 concerns some car-to-car contacts in multiplayer.

The update replaced the previous TCP-based connection system with Reliable UDP, or RUDP, as part of a broader overhaul of the game’s online infrastructure. Studio 397 had already indicated that problems could emerge as the new system was deployed more widely.

Since the update, some multiplayer incidents have involved relatively minor contact producing unusually severe reactions from one of the cars.

Studio 397 made RUDP-related adjustments in V1.4.0.3 on July 31, including changes intended to improve online stability.

Brake cooling issue can push temperatures towards 900°C

A separate issue affects brake cooling.

In some sessions, brake ducts can behave as though they are fully closed regardless of the selected setup, causing brake temperatures to rise excessively or preventing them from cooling as expected.

Reported cases have seen temperatures approach 900°C, with a direct effect on braking performance. The problem has been reported in both online and offline sessions.

Version 1.4 also introduced a reworked braking system, including changes to the thermal model and brake pad performance curves.

Studio 397 has released several hotfixes

Multiple updates have followed Version 1.4.

Patch V1.4.1.0, released on August 10, addressed server stability, AI pit behavior, RaceControl, online competitions, netcode and other areas. Another hotfix followed on August 11.

V1.4.1.2 arrived on August 17, bringing further fixes for online championships, hosted servers, protests, RaceControl, the interface and VR. Its release notes did not list a specific fix for the brake duct problem or the multiplayer contact behavior cited around the competition suspensions.

Motorsport Games is investigating

Motorsport Games President and CEO Stephen Hood has confirmed that the company is investigating the reported deterioration in the online experience.

Hood said the team does not necessarily believe RUDP itself is responsible and is examining whether other development changes could be contributing to the problems.

For now, neither Low Fuel Motorsport nor Virtual Motorsport Series has announced when its affected competition will resume.
