Ok So I tried it on the dedicated server + 2 separate clients.
If the client window is focused it only updates (click on any of the clients and the other one doesn’t update then, not a bug probably just the way processes are run)
If I put the focus on the dedicated server (with -log command to show it’s console), both clients update in sync.
Here is the dedicated server version showing how it updates
Here is the c++ version with client and server target files
