I have tried this only in single player. Even tried running it with a dedicated server running on the same PC in another folder. Didn't work. Still got the constant pop-ups. Tried it with minimal settings. All sorts of different settings configurations actually. Even when the game is reporting over a 100fps I am still getting the server notices pop-ups in game. Task Manager was reporting less then 70% of the total CPU speeds being used the times I tried seeing what that might have to say.
No matter how I tried to reconfigure my computer and or starmade I get constant pop-up notices in game about "Server Under Heavy Load".
I did a reinstall and ran the game with all default settings. Except for memory and using a java.jar with ran by a bat limiting java memory to the same amount as the game is set to. I have tried this with the windows starmade exe. It doesn't made any difference.
The launcher is installed to "C:\000\Starmade\Game"
The game is installed to "C:\000\Starmade\Game\StarMade"
I have tried different install locations. Even installed it using steam. Nothing different.
