How To Reset Cvar To default

Greetings

I have some questions concerning the cvar ( used in config file) , well a while ago i used 3 cvars specifically : /Set M2faster 3 , SET gxTextureCacheSize '"value"(vram allocation ) and SET timingMethod "value" , i had gained some smootness in game with this but a week ago i changed my gpu ( new one with less memory) .
I'd like to know please , how can i revert back these cvars to default , are they saved within the server or in my pc ??
Thanks for reading , and i apologize for my poor english
Kind regards =)

They are saved in your PC, inside (Game folder)\WTF\Config.wtf. Quit the game, open the file with Notepad, delete those lines, save it, then launch the game again.

Thank you Shred92 , i just deleted them
Have a good day =)
