this is allready a lot in svencoop, so how many players should play it ? And what is the Epoly count ? Svencoop have big performance issues and with additional wpolys/epoly masses the game starts to kill the latency.
( Allways check the MS in the console if these go far beyound 10 ms, it starts to getting worse. )
If you are intrested in any further help let me know, i sure can help
