Property's for editing gmod startup options.

hi yes if you read my other post my gmod starts up for a plit second then shutsdown i know the issue can be solved by putting something in the launch thing. But 1 problem i dont have that launch thing. When i click property’s Theres no option saying start up options which means i cant get rid of window mode i need help on finding the startup options.

to sum it up. I cannot locate startup options in propertys.


Nevermind somone close this thread im such an idiot i have to open steam then right click gmod from there.
