I've monitored the server all the time and write all the 9 missions.
No scripting at all.
Only the ingame trigger system and very simplified to avoid crash.
Only in the last big mission, i have drops in FPS (server) and minor lags (clients).
In the 8 other missions-> No problem at all.
The server is a Apple MBP 13" with 2,5Ghz Core I5 (3210M). 16Go. HD4000.
Autoexec.cfg with no render and 30FPS max.
In settings, the server with LAN but all clients with ADSL 2048.
2x100mbits switch.
Goz.
