I seem to be having a related, but slightly different issue-
When I play vintage story, I notice it absolutely peaks my wifi sometimes, and makes any videos I am playing on my 2nd moniter just lag out completely or stutter like crazy. I know it's a wifi issue because I can see it peaking on task manager, and it only happens when I'm playing VS. I thought it was a CPU issue at first, but it isn't, it says the wifi is the only thing peaking.
It's not game-breaking, and it doesnt actually affect my internet's speed, but it is just super annoying to deal with if I want to listen to any video while playing the game
