Every time I open Garry’s Mod (v10), the only content available for use is the custom content I downloaded from GarrysMod.org and the content from Half-Life 2 and Garry’s Mod. But, I also have Counter Strike: Source and Portal installed on my system, as well as HL2: Episodes 1 and 2. Shouldn’t those maps and objects appear as well?
My Machine is an Athlon X2 DC 3800+ with an Nvidia Geforce 9600 GT
