Esc and trench compute hang up

Hi all!
So anyone else got a problem with esc? When i reach a certain point like 10k (yes i play esc and trench) the computer have serious problem handling that mass of troopers.... it can even go so far that the script start to not respond, quiet frustrating!
I only have this problem at work:) not at home where my computer is a bit newer...
Is there anything i can do to keep playing at work?:) ANd i know other have the same problem...
Thx
