Change and save vars of graphics etc

I like change the vars for example:


From BP i need to use the execute command but that don’t save the changed var for next run ?
I’m using the Rama’s Victory Plugin to load and save custom vars, and i got my custom vars but i need read my var for example myTextureQuality and then set throw the execute command the r.MaxAnisotropy when the game is running, i can change the var r.MaxAnisotropy permanently ?
