At least it appears to be something that gets triggered. In theory, if a node is not under attack or heavy usage, this isn’t a consideration. Doesn’t seem to be a perfect solution as it still slows the traffic of legitimate users in the event of an attack. I don’t know the full details, but in the worse case it makes it easier to semi-DoS, maybe not by fully making a node unresponsive, but by making the service so painfully slow that users may give up on it.

I just tried it on Nobara. Just… application launcher (The start menu icon)->sleep. Waited, and then woke the machine back up and when the machine came back up, the game was still running. No idea if all games will play nice with that, but Satisfactory did.
