Are changes made by commands executed once at the start of the game kept through the different levels, and saved when the game is closed?

Let me explain: I am using commands to change my graphics settings. Will these settings be saved from one level to another? And will they be saved after exiting the game? Same question for keyboard keys, with Save Key Mappings. Thx

If you use the specific save blueprint nodes, yes. For instance SaveUserSettings, because it gets written to the config file.

But commands from the console, no.

Thanks for your answer!
