A suggestion:
A param to disable the threading for servers that was enforced a few patches ago.
100% cpu usage on high end boxes with low player count due to the threading introduced.
This is causing multiple issues within the game. FPS gains with the threading enabled are/were minimal and in my opinion not worth the CPU usage it costs.
7 server instances 181 players between. (highest pop server was 60)
