FGear Vehicle Physics (v1.4)

[Looking for help with a bug]
Hi there, I’m seeking assistance with a specific issue in my Unreal Engine 5.1 source build multiplayer game.

The game is running on a dedicated server and utilizes the fgear system. I’ve encountered a peculiar problem: once there are six players on the server with six or more cars actively driving around, all six cars experience sudden and severe performance degradation. It’s as if they’re affected by extreme packet loss and high ping, rendering them undriveable. Interestingly, other aspects of the server, such as player movement, remain unaffected, and network saturation doesn’t seem to be the cause.

any advise on things I should check and or could try would be greatly appreciated Im quite stuck and have tried emailing the plugin developer
