FPS fluctuating significantly

Studio Operators Composer Unreal


Hi I'm getting this error repeatedly after opening UE4 scene in Aximmetry. Can some one tell me how to fix it.

LogUdpMessaging] StartTransport failed to create multicast socket on, joined to with TTL 1

[LogUdpMessaging] UDP messaging encountered an error. Auto repair routine started for reinitialization

If you are using VPN, this might be related to that. You could look up a solution on Unreal forums if it causes other problems than just the log messages.
Otherwise, if you are not using UDP network messages in Unreal, you can turn it off by going to Project Settings in Unreal, then under UDP Messaging uncheck the Enable Transport box.

Warmest regards,
