Steam > Counter-Strike: Global Offensive > Properties > General > Set Launch Options:
-novid -tickrate 128 +exec bananagaming.cfg -language bananagaming -d3d9ex

Launch options explained:
-novid = Remove the Valve intro that normally plays at the beginning. A must-have launch option in my opinion.
-tickrate 128 = If you create an offline game with bots, the created server will run at tickrate 128 instead of 64.
+exec bananagaming.cfg = Makes sure my config runs every-time I start the game. Change “bananagaming” to your configs own name.
-language bananagaming = This launch option is to launch the “Text Color Mod".
-d3d9ex = Makes tabbing in and out from Fullscreen much faster.
