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.
2 server instances 6 players between. (highest pop was 3) (CPU usage goes to 100% with anything above 50 players)
2 server instances 17 players between. (highest pop was 14) (CPU usage goes to 100% with anything above 50 players)
