--- Comment #30 from jeppe winther jeppewinther@gmail.com --- Well. What you're trying to add to the execution of the program is called an Argument. Normally you append them after the instruction to execute said program, in order to give additional instructions on how the program should run and behave. The easiest way to see them in action is to open up a terminal and comparing the following commands invoking the ls program (no quotation marks): "ls" "ls -l" "ls --help"
With playonlinux, you have to Configure your shortcuts to add arguments to them. http://wiki.playonlinux.com/index.php/The_Configuration_Window#The_Main_Conf... Have a look at the second image on this page, the one with all the red boxes and numbers. You'll want to add the arguments in the "Arguments" box, here number 16. So, in there write "-gc 100", again no quotation marks. I still don't think -ns is necessary, but experiment away.
