Sporadic processor usage when upgrading from u4.6 to u5.3

My company deveoped a simulation game with a server-client system. A serverclient is hosted on a windows server as an instance for each group(party) that plays the game and controls the NPC GameObjects. Usually there are three clients that connects to this server instance.
With u4.6 RakNet networking system we got a fairy stabile connection and use of processing power. With a vanilla upgrade to U5.3 the processing power of the instance jumps all over the place and causes serious server instabillities. I am not shure that the networking is really the issue here but rather the software itself. It is running with: “-batchmode -nographic -nolog” arguments.

If anyone have any thoughts about what the issue could be it would be most appreciated. :slight_smile:

Judging from your symptoms and processor I would say it’s this one: Unity games consume 100% CPU on MANY titles. - Unity Engine - Unity Discussions

Ah… I see. Seems like this actually is a bug issue beeing dealt with. Thank you for your reply :slight_smile:
