Studio 397 has released Le Mans Ultimate 1.4.1.3, temporarily rolling back several networking changes introduced with Version 1.4 while development of its Reliable UDP system continues. The update follows several weeks of work on Le Mans Ultimate’s online infrastructure after Version 1.4 launched on July 28. Studio 397 says some of the initial connection problems were addressed by subsequent patches, but certain connection types are still experiencing issues during online races. Le Mans Ultimate returns to its previous networking setup Version 1.4 replaced TCP game connections with Reliable UDP, or RUDP, as part of a wider overhaul of Le Mans Ultimate’s online infrastructure. With Version 1.4.1.3, Studio 397 has decided to temporarily return regular servers to the previous networking configuration while further work continues on RUDP. The problems do not appear to affect every player or every online session. Studio 397 is investigating how different connection types and network conditions interact with the newer system. The change is particularly relevant after recent discussion around Le Mans Ultimate’s netcode and car-to-car contact behaviour. RUDP has not been abandoned The rollback does not mean Studio 397 is dropping RUDP. The developer still believes the protocol can help reduce disconnects and address limitations in the previous networking system, but more testing is required before it returns to regular servers. Dedicated public RUDP test sessions are planned over the coming weeks. These sessions will allow Studio 397 to collect data from players using different internet providers, connection types and locations. Regular Le Mans Ultimate servers will use the previous networking configuration while those tests take place. Version 1.4.1.3 fixes a server lock-up problem The update also addresses a netcode-related issue that could cause servers to become stuck or lock up. Studio 397 will continue gathering connection data while working towards a more stable implementation
